Answer:
d).2
Step-by-step explanation:
Use the following equation:
slope (m) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (1 , -3)
(x₂ , y₂) = (2 , -1)
Plug in the corresponding numbers to the corresponding variables:
m = (-1 - (-3))/(2 - 1)
Simplify. Combine like terms. Remember to follow PEMDAS. Remember that two negatives = one positive:
m = (-1 + 3)/(2 - 1)
m = (2)/(1)
m = 2
d).2 is your slope.

The Garcia family and the Lee family each used their sprinklers last summer. The Garcia family's sprinkler was used for 40 hours. The Lee family's sprinkler was used for 20 hours. There was a combined total output of 2000L of water. What was the water output rate for each sprinkler if the sum of the two rates was 60L per hour?
Answer:
Lee= 20 L per hour.
Garcia = 40L per hour
Step-by-step explanation:
This formula is:
40x + 20y = 2000L
with if being known that x + y = 60.
In this x is the rate for Garcia and y is the rate for Lee.
You can also say that x = 60 - y, which you can fill in.
40 * (60-y) + 20y = 2000
2400 - 40y + 20y = 2000
-20y = -400
y = 20 L per hour.
So x = 60 - 20 = 40L per hour

Y=8x-3/-4x-10 has a vertical asymptote with equation(enter equation of the vertical asymptote
Answer:
x=-2.5 if the function is [tex]f(x)=\frac{8x-3}{-4x-10}[/tex]
Step-by-step explanation:
[tex]y=\frac{8x-3}{-4x-10}[/tex] has discontinuities when the denominator is 0.
You will either have a hole or a vertical asymptote depending on what happens to the numerator after you find when the bottom is 0.
That is whatever you found that makes the bottom 0, if it makes the top also 0 then you will have a hole at x=the number that made the bottom 0.
If it makes the top anything other than 0, then it is a vertical asymptote at x=the number you found that made the bottom 0.
Let's do this now.
When is -4x-10 equal to 0?
We have to solve the equation:
-4x-10=0
Add 10 on both sides:
-4x=10
Divide both sides by -4:
x=10/-4
Reduce by dividing top and bottom by 2:
x=5/-2
x=-5/2
or
x=-2.5 (if you want decimal form)
Now does it make the top 0? This is the deciding factor on whether you have a hole at x=-2.5 or a vertical asymptote at x=-2.5.
Let's see.
8(-2.5)-3=-23
Since the top is not 0 at x=-2.5 then you have a vertical asymptote at x=-2.5.
If the top were 0, then you would have had a hole at x=-2.5.

How do you graph this and know if it is continuous or not?
Answer:
Continuous because there are no breaks.
The graph is included as an attachment.
Step-by-step explanation:
Alright we want to graph:
y=x-4 for x<2
y=-2x+2 for x=2 or x>2
So let's graph the first piece y=x-4 for x<2.
I'm going to plug in 2 for x: y=2-4=-2. So this one line is going to contain an open circle at (2,-2). I say open circle because we did not have that we could actually include x=2 here because it says for x less than 2.
Now we are going to enter in one more number less than 2....your choice.
Let's go with x=0. When you plug in 0 for x into y=x-4 you get y=0-4=-4. So our line is going to include (0,-4).
So we are going to graph the points (0,-4) and (2,-2) again where (2,-2) is an open circle. Connect these points. You may extend your line left because we have x<2, but do not extend it right of x=2.
Let's look at the other piece now: y=-2x+2 for x=2 or x>2.
I'm going to plug in 2 for x: y=-2(2)+2=-4+2=-2 so we are going to include the point (2,-2) on our line. This was actually a point we used from above that we didn't want to include. We do now want to include because of the x=2 in our inequality so the dot can now be filled in. We need one more point to graph this line. Let's plug in a number greater than 2 since our inequality say x=2 or x>2. You choose. How about x=3?
y=-2(3)+2=-6+2=-3. So we are going to include the point (3,-3). So starting at (2,-2) and going right to connect it to (3,-3), you could extend passed the (3,-3) to the right.
I will show you my graph.
There are no breaks in the "curve", so it is continuous for all real numbers.

m<3+m<4+m<5=180
m<5+m<6=180
m<2+m<3=m<6

Answer:
m∠5+m∠6=180°
m∠2+m∠3=m∠6
m∠2+m∠3+m∠5=180°
Step-by-step explanation:
Verify each option
case A) we have
m∠5+m∠3=m∠4 ----> equation A
we know that
m∠3+m∠4=180° -----> by supplementary angles
m∠4=180°-m∠3 ----> equation B
substitute equation B in equation A
m∠5+m∠3=180°-m∠3
m∠5+m∠3+m∠3=180°
This equation is true when m∠2=m∠3
therefore
Is not always true
case B) we have
m∠3+m∠4+m∠5=180° ----> equation A
we know that
m∠3+m∠4=180° -----> by supplementary angles
m∠4=180°-m∠3 ----> equation B
substitute equation B in equation A
m∠3+(180°-m∠3)+m∠5=180°
m∠5=0°
This option is not true
case C) we have
m∠5+m∠6=180°
we know that
m∠5 and +m∠6 are supplementary angles
so
Their sum is always 180 degrees
therefore
This option is always true
case D) we have
m∠2+m∠3=m∠6 -----> equation A
we know that
m∠5+m∠6=180° ----> by supplementary angles
m∠6=180°-m∠5 ----> equation B
substitute equation B in equation A
m∠2+m∠3=180°-m∠5
m∠2+m∠3+m∠5=180°
Remember that the sum of the interior angles of a triangle must be equal 180 degrees
therefore
This option is always true
case E) we have
m∠2+m∠3+m∠5=180°
Remember that the sum of the interior angles of a triangle must be equal 180 degrees

Estimate the value of \sqrt(14)+\sqrt(3) to the nearest hundredth.
A. 3.79
B. 5.47
C. 2.01
D. 4.12
Answer:
B.
Step-by-step explanation:
Let's figure out what two consecutive integers is 14 between.
We also need to do this for 3.
14 is between 9 and 16 which means [tex]\sqrt{14}[/tex] is between [tex]\sqrt{9}[/tex] and [tex]\sqrt{16}[/tex].
3 is between 1 and 4 which means [tex]\sqrt{3}[/tex] is between [tex]\sqrt{1}[/tex] and [tex]\sqrt{4}[/tex].
So 14 is closer to 16 which means [tex]\sqrt{14}[/tex] is closer to 4. Let's say [tex]\sqrt{14}\approx 3.7[/tex]
So 3 is closer to 4 which means [tex]\sqrt{3}[/tex] is closer to 2. Let's say [tex]\sqrt{3}\approx 1.8[/tex].
So now we do 3.7+1.8=5.5.
The answer that is closet to this is 5.47.
Now if we put [tex]\sqrt{14}+\sqrt{3}[/tex] in our calculator we get:
3.74+1.73=5.47

[tex]W=\begin{cases}9&\text{if the sum is odd}\\4&\text{if the sum is 4 or 8}\\49&\text{if the sum is 2 or 12}\\-1&\text{otherwise}\end{cases}[/tex]
First thing to do is determine the probability of each of the above events. You roll two dice, which offers 6 * 6 = 36 possible outcomes. You find the probability of the above events by dividing the number of ways those events can occur by 36.
The sum is odd if one die is even and the other is odd. This can happen 2 * 3 * 3 = 18 ways. (3 ways to roll even with the first die, 3 ways to roll odd for the die, then multiply by 2 to count odd/even rolls)The sum is 4 if you roll (1, 3), (2, 2), or (3, 1), and the sum is 8 if you roll (2, 6), (3, 5), (4, 4), (5, 3), or (6, 2). 8 ways.The sum is 2 if you roll (1, 1), and the sum is 12 if you roll (6, 6). 2 ways.There are 36 total possible rolls, from which you subtract the 18 that yield a sum that is odd and the other 10 listed above, leaving 8 ways to win nothing.So the probability mass function for this game is
[tex]P(W=w)=\begin{cases}\frac12&\text{for }w=9\\\frac29&\text{for }w=4\text{ or }w=-1\\\frac1{18}&\text{for }w=49\\0&\text{otherwise}\end{cases}[/tex]
The expected value of playing the game is then
[tex]E[W]=\displaystyle\sum_ww\,P(W=w)=\frac{71}9[/tex]
or about $7.89.
The expected value is positive, so a player can expect to earn money in the long run, and so should play the game.

Shane biked 1 mile than three times the number of miles lissette bike a total of 7 miles. Write an equation to determine how many miles lissette bike
To find the number of miles Lissette biked, the provided information leads to an algebraic equation where Lissette's distance is represented as 'x' and Shane's as '3x + 1', combining to equal 7 miles.
The subject of this question is mathematics, specifically algebra, where you need to write an equation based on a word problem.
The problem states that Shane biked 1 mile more than three times the number of miles Lissette biked, and their combined total is 7 miles. If we let x represent the number of miles Lissette biked, then Shane biked 3x + 1 miles. The equation to determine the number of miles Lissette biked is:
x + (3x + 1) = 7

Give the equation of the line passing through the point (20,2)that is perpendicular to y=−4x.
Answer:
y-2 = 1/4(x-20) point slope form
y = 1/4x -3 slope intercept form
Step-by-step explanation:
y = -4x
The slope is -4
The slope that is perpendicular is the negative reciprocal
- (1/-4) = 1/4
The slope of our new line is 1/4
We have a point and the slope, so we can use point slope form
y-y1 = m(x-x1)
y-2 = 1/4(x-20)
If we want the line in slope intercept form, distribute
y-2 = 1/4x -5
Add 2 to each side
y-2+2 = 1/4x -5+2
y = 1/4x -3

What is the factored form of 3x2 + 5x - 12?
Answer:
[x + 3][3x - 4]
Step-by-step explanation:
First off, we need to find two numbers that when differed to 5, they also multiply to -36 [3 × -12]. Those numbers are -4 and 9. Next, we find the Greatest Common Factor [GCF], which means the LEAST DEGREE TERM possible:
[3x² - 4x] + [9x - 12]
x[3x - 4] 3[3x - 4]
As you can see, whenever we have a leading coefficient greater than 1, we need to break up our B into our two numbers we found [in BOLD], and have to attach an x to them because it replaced Bx, according to the Quadratic Equation of y = Ax² + Bx + C. So, after we completed our factoring, you see two identical factors, which we use ONCE. The other factor comes from the terms outside the duplicates. So, you get the above answer after you completed the steps: [x + 3][3x - 4].

x/3 = 1/5 x 10
x/3 = 10/5
x = 10/5 x 3
x = 6
The number is 6.

What is the diameter of the circle whose center is at (6, 0) and that passes through the point (2, -3)?
A. (x+16)2+(y+30)2=1156
B. (x+16)2+(y+30)2=34
C. (x−16)2+(y−30)2=34
D. (x−16)2+(y−30)2=1156
Answer:
The diameter is 10 units.
The equation of the circle is [tex](x-6)^2+y^2=25[/tex].
Step-by-step explanation:
You ask for the diameter but the choices give you the equation of the circle?
I will do both.
So they actually tell us the radius is from (6,0) to (2,-3).
So the radius is whatever that length is. We can find the length by using the distance formula.
[tex]d=\sqrt{(6-2)^2+(0-(-3))^2}[/tex]
[tex]d=\sqrt{(4)^2+(3)^2}[/tex]
[tex]d=\sqrt{16+9}[/tex]
[tex]d=\sqrt{25}[/tex]
[tex]d=5[/tex]
So the radius is 5.
The diameter is twice the radius so the diameter is 2(5)=10.
Now the equation of our circle which doesn't match any of the choices is
[tex](x-6)^2+(y-0)^2=5^2[/tex].
You are probably wondering how I got that. I used the center-radius form for a circle which is [tex](x-h)^2+(y-k)^2=r^2[/tex].
The center is (h,k) and the radius is r.
We had the center for our circle was (6,0) and the radius was 5.
I'm going to simplifying our equation just a bit:
[tex](x-6)^2+y^2=25[/tex].
All I did was y-0 which is y and 5^2 which is 5(5) which equals 25.
In a triangle, the measure of the second angle is twice the measure of the first angle. the third angel is equal to the sum of the other angels
Answer:
So the angles have measurements 30,60, and 90 degrees.
Step-by-step explanation:
We have a triangle which means the interior angles of that triangle has sum 180 degrees.
Let's call the angle measurements: A, B, and C.
A+B+C=180
B=2A (The second angle is twice the first.)
C=A+B (The third angle is the sum of the other 2.)
If C=A+B, then C=A+2A (since B=2A).
So we have this system:
A+B+C=180
B=2A
C=3A (since C=A+2A=3a).
Now I'm going to use the first equation A+B+C=180 and plug in the other equations we have below it:
A+B+C=180 with B=2A and C=3A.
A+2A+3A=180
6A=180
Divide both sides by 6:
A=180/6
A=30
If B=2A and A=30, then B=2(30)=60.
If C=3A and A=30, then C=3(30)=90.
So the angles have measurements 30,60, and 90 degrees.

cos theta = -4/5.
sec theta = -5/4.
tan theta = 3/4.
cot theta = 4/3.
Step-by-step explanation:
sin^2 theta + cos^2 theta = 1
(-3/5)^2 + cos^2 theta = 1
cos^2 theta = 1 - 9/25
cos^2 theta = 16/25
cos theta = -4/5 (negative because it is in Quadrant 3).
sec theta = 1 / cos theta = -5/4.
tan theta = sin theta / cos theta = -3/5 / - 4/5
= -3/5 * -5/4
= 3/4.
cot theta = 1 / tan theta = 4/3.
The other trigonometric functions can be found using the Pythagorean Identity and the definitions of the trigonometric functions. The values are cos theta = -4/5, tan theta = 3/4, csc theta = -5/3, sec theta = -5/4, and cot theta = 4/3.
Explanation:The given values are sin theta = -3/5 and cos theta = -5/3, which are located in quadrant 3. In this quadrant, sine and cosine are both negative. To find the values of the other trigonometric functions, we will use the Pythagorean Identity and the definitions of the trigonometric functions.
We can find cosine through the Pythagorean Identity, sin² theta + cos² theta = 1. Solving for cos theta, we get cos theta = sqrt(1 - sin² theta) = sqrt(1 - (-3/5)²) = -4/5. Note the negative sign since we are in quadrant 3.
Next, we can find tan theta = sin theta/cos theta = (-3/5) / (-4/5) = 3/4.
For the reciprocal functions, we have csc theta = 1/sin theta = -5/3, sec theta = 1/cos theta = -5/4, and cot theta = 1/tan theta = 4/3.

Find the quadratic function that fits curve below. Select the correct answer.
The answer is:
The quadratic function that fits the given picture is:
[tex]y=-3x^{2}+13x-5[/tex]
Why?We can solve the problem and find the correct function that fits the curve below by finding which function intercepts the y-axis at -5 (we can see it from the picture), also, we need to look for a function that represents a parabola opening upwards. We need to remember that when a parabola is opening upwards, its quadratic term coefficient is negative.
So, we can see that from the given functions, the only function that represents a parabola opening upwards and its y-intercept is located at y equal to -5 is the second option:
[tex]y=-3x^{2}+13x-5[/tex]
We have that :
[tex]a=-3(negative)\\b=13\\c=-5(y-intercept)[/tex]
We can see that the quadratic term (a) is negative, and the quadratic function intercepts the y-axis at y equal to -5.
Hence, the answer is:
The quadratic function that fits the given picture is:
[tex]y=-3x^{2}+13x-5[/tex]

Samuel has 5 bags of almonds. A full bag weighs 3 pounds. How many pounds of almonds does Samuel have? (Multiply)
A.15 Pounds
B.12 pounds
C.8 pounds
Answer:
15 pounds
Step-by-step explanation:
5 bags @ 3 pounds
5 x 3 = 15 lbs.
Samuel has 5 bags of almonds, each weighing 3 pounds. By multiplying the number of bags by the weight of each bag (5 * 3), we find that Samuel has a total of 15 pounds of almonds.
The total weight of Samuel's 5 bags of almonds is:
Multiply the weight of a full bag (3 pounds) by the number of bags (5): 3 pounds/bag x 5 bags = 15 pounds
Therefore, Samuel has 15 pounds of almonds.
