Answer:

[tex]m=-18[/tex]

Step-by-step explanation:

1. The line contains the points (34,12) and (32,48). Then, you need to use the slope formula, which is:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

2. When you substitute values into the formula, you obtain:

[tex]y_{2}=48\\y_{1}=12\\x_{2}=32\\x_{1}=34[/tex]

[tex]m=\frac{48-12}{32-34}\\m=\frac{36}{-2}\\m=-18[/tex]

Hello,

Question:

Keisha solved the following equation:

4x − 2x + 8 = 6(x + 4)

Which step has an incorrect justification? (Make sure to type only the number of the step into the blank: 1, 2, 3, 4 or 5)

Correct Solution:

x − 2x + 8 = 6(x + 4)

4x + −2x + 8 = (6) (x) + (6) (4) (Distribute)

4x + −2x + 8 = 6x + 24

(4x + −2x) + (8) = 6x + 24 (Combine Like Terms)

2x + 8 = 6x + 24

2x + 8 = 6x + 24

Subtract 6x from both sides.

2x + 8 − 6x = 6x + 24 − 6x

−4x + 8 = 24

Subtract 8 from both sides.

−4x + 8 − 8 = 24 − 8

−4x = 16

-4 x -4 = 16

x = -4

Answer:

Where keisha went wrong was forgeting to subtract 6x to both sides.

Incorrrect step is #3

The solution to the equation is correct.

on the line - 4x + 8 = 24 to the next line

Answer:

The correct answers are "After adding the 0 test score, the mean would be affected.", ad "Before the missed test, Eva’s median score was 91".

Step-by-step explanation:

We know that the mean and median scores would not be helpful in determining Eva's abilities since the 0 is not a representation of how much she knows. However, it will affect the average as adding a 0 to the numerator and a 1 to the denominator will lower the average.

Finally, we can tell the median is 91 before added as when we line up the scores in ascending order, the middle number is 91.

82, 90, 91, 96, 100

Answer:

Statements that are true based on the data:

-After adding the 0 test score, the mean would be affected.

-After adding the 0 test score, the median would be the most appropriate measure of center to describe the data.

-Before the missed test, Eva’s median score was 91.

-Before the missed test, Eva’s mean score was 91.8.

Step-by-step explanation:

-After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data: NO, it won't because the data now has an extreme value that shifts the mean value significantly.

-After adding the 0 test score, the mean would be affected: YES, The mean value would be greatly impacted by adding the 0, (mean=76.5 with the 0; 91.8 without the 0),

-After adding the 0 test score, the median would be the most appropriate measure of center to describe the data: YES, because the median won't be affected as much as the mean by the extreme value.

-Before the missed test, Eva’s median score was 96: NO, the median score was 91 at that point.

-Before the missed test, Eva’s median score was 91: YES, the median score was 91, the median is defined as the value where 50% of sorted values are below and 50% are above

-Before the missed test, Eva’s mean score was 91.8: YES, the mean is defined as the sum of all values divided by the total number of values

The formula for calculating the median is:

-odd number of values: [tex]$ x_m = x_\frac{n+1}{2}[/tex]

-even number of values: [tex]$ x_m = \frac{x_\frac{n}{2}+x_\frac{n+2}{2}}{2}[/tex]

MEDIAN BEFORE ADDING THE 0: 82,90,91,96,100

[tex]$ x_m = x_\frac{5+1}{2}[/tex]=3 (third value)

MEDIAN AFTER ADDING THE 0: 0,82,90,91,96,100,

[tex]$ x_m = \frac{x_\frac{6}{2}+x_\frac{6+2}{2}}{2}[/tex]=average between the 3 and 4 values

[tex]$ x_m = \frac{90+91}{2}[/tex]=90.5

The formula for calculating the mean is: [tex]mean ={\frac{1}{n} \sum_{i=1}^n (x_i) $[/tex]

MEAN BEFORE ADDING THE 0

[tex]mean ={\frac{1}{5} \sum_{i=1}^5 (x_i) $[/tex]=[tex]\frac{459}{5}[/tex]=91.8

MEAN AFTER ADDING THE 0

[tex]mean ={\frac{1}{6} \sum_{i=1}^6 (x_i) $[/tex]=[tex]\frac{459}{6}[/tex]=76.5

Answer:

[tex]m\angle c = 30^\circ[/tex]            

Step-by-step explanation:

We are given the following information in the question:

ΔABC and ΔDEF

[tex]\angle A \cong \angle D\\\angle B \cong \angle E\\m\angle c = x \\m\angle F = 2x-30[/tex]

According to angle sum property of the triangle the sum of all angles of triangle is equal to 180 degrees.

Since two corresponding angles of the two triangle are equal, therefore the third angle is also equal.

[tex]x = 2x - 30\\\Rightarrow x = 30[/tex]

Thus,

[tex]m\angle c = 30^\circ[/tex]

The measure of the angle from the given information is m∠C = 2x - 30°

Given the information, we have two separate triangles: ABC and DEF.

In triangle ABC, we are given that ∠A ≅ ∠D and ∠B ≅ ∠E.

In triangle DEF, we are given that m∠C = x and m∠F = 2x - 30°.

To find m∠C, we need to find the value of x.

Since ∠A ≅ ∠D, and ∠B ≅ ∠E, we can conclude that triangle ABC is congruent to triangle DEF by the Angle-Angle (AA) congruence criterion.

Using this congruence, we can determine that m∠C = m∠F.

Therefore, we have:

m∠C = m∠F

Since we know that m∠F = 2x - 30°, we can substitute this value into the equation:

m∠C = 2x - 30°

This gives us the measure of angle C in terms of x.

Hello there,

So you have two fractions 2/5 and 1/4, but none of them have the same denominator... However a LCD that you can get from both of these is 20, so if you multiplied 4 on the top and the bottom for 2/5, you would get 8/20, and for 1/4, multiply 5 on the top and the bottom, and soon you end up with 5/20. If you added these two fractions together, now knowing that they have the same denominator... you would end up with 13/20 which is the answer to your problem.

Hope this was helpful for you :)

Answer:

B. 0.075 in

Evan apparently divided by time. He might do that if he were not paying attention to units.

Step-by-step explanation:

The given rainfall rate is ...

... (1.5 in)/(60 s) = (1/40) in/s = 0.025 in/s

To find the rainfall in 3 s, you need to multiply rate by time:

... (0.025 in/s)×(3 s) = 0.075 in

If you keep the rate and time in terms of minutes, then you have:

... (1.5 in/min)×(0.05 min) = 0.075 in

_____

Evan apparently divided, instead. His number is not inches.

... (1.5 in/min)/(0.05 min) = 30 in/min² . . . . not the appropriate units for the problem

The correct amount of rain that fell in 3 seconds at Brasse Terre, Guadalupe, is 0.075 inches, as calculated by multiplying the rate of 1.5 inches per minute by 0.05 minutes. Evan made an error leading to answer D, which is incorrect.

In 1970, a record 1.5 inches of rain fell in one minute. To find out how much rain fell in 3 seconds, which is 0.05 of a minute, we need to multiply the rate of rainfall by the fraction of the minute we are interested in. The calculation is as follows:

1.5 inches/minute x 0.05 minute = 0.075 inches

Evan seems to have misunderstood the calculation, leading to answer D, but the correct amount of rain that fell in 3 seconds is 0.075 inches, which corresponds to option B.

Answer:

x = -2

Step-by-step explanation:

3x -8 =8x +4/2

the x-intercepts of cosx are

[tex]\frac{\pi }{2}[/tex] and [tex]\frac{3\pi }{2}[/tex] on [0, 2π )

The x-intercepts of the function f(x) = cos(x) on [0, 2π) are π/2 and 3π/2.

The x-intercepts of the function f(x) = cos(x) on the interval [0, 2π) can be found by setting f(x) equal to zero and solving for x.

cos(x) = 0

To find the values of x for which cos(x) equals zero, we need to determine when the cosine function equals zero on the given interval. The cosine function equals zero at every multiple of π/2. Therefore, the x-intercepts of f(x) are π/2 and 3π/2.

9g = 3(5g - 4)

3g = 5g - 4

3g - 5g = -4

-2g = -4

g = -4/-2 = 4/2

Answer: g = 2

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

9g=3(−4+5g)

9g=(3)(−4)+(3)(5g)(Distribute)

9g=−12+15g

9g=15g−12

Step 2: Subtract 15g from both sides.

Answer:

the answer is -7

Step-by-step explanation:

thxs person who answered before me :)

The straight line joining the points A(3,-5) and B(6,k) has a gradient of 4.

Gradient is the slope

So the slope of the line joining the points A(3,-5) and B(6,k) is 4

Slope of line joining two points = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

A(3,-5) and B(6,k) are (x1,y1)  and (x2,y2)

slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

slope = [tex]\frac{k-(-5)}{6-3}=\frac{k+5)}{3}[/tex]

We know slope =4

 [tex]\frac{k+5)}{3}=4[/tex]

Cross multiply  and solve for k

k + 5 = 12

k = 7

The value of k = 7

The future value (A) of a one-time investment of principal amount P at interest rate r compounded n times per year for t years is ...

... A = P(1 +r/n)^(nt)

Putting your given numbers into the formula, we have

... 876.34 = 300(1 +.06/4)^(4t)

Taking logarithms, this becomes the linear equation

... log(876.34) = log(300) + 4t·log(1.015)

Solving for t in the usual way, we get

... log(876.34) -log(300) = 4t·log(1.015) . . . . . . . subtract the constant term on the right

... (log(876.34) -log(300))/(4·log(1.015)) = t ≈ 18.00 . . . . divide by the coefficient of t

It will take 18 years for the $300 CD to reach a value of $876.34.

You found CD from the Pythagorean theorem to be ...

... CD = √(5² -2²) = √21

Since triangle ADC ~ triangle ACB, the ratios of corresponding sides are the same:

... AC/AD = AB/AC

... AB = AC²/AD

... AB = 5²/2 = 12.5 . . . . . . . the base of the overall triangle

_____

Then the area (A) is ...

... A = (1/2)bh

... A = (1/2)(12.5)(√21) ≈ 28.64 square units

_____

As you see here, the altitude of a right triangle divides it into three similar triangles. From smallest to largest, they are ...

... ADC ~ CDB ~ ACB

You can figure this using AAA similarity, since the smallest and largest triangles listed above share an acute angle vertex (∠A). That, together with the right angle, means all angles are congruent. After that, then you know ∠ACD ≅ ∠CBD, so you can show the middle sized triangle is similar to the other two.

if r perpendicular to s then angles 1,2,3,4=90 deg.

If two different lines intersect a third line at the same angle then they must be parallel.

r and t intersect s at the angle 2=90 deg  and 6 = 90 deg, therefore r and t are parallel.

Answer:

B) f(x) = -3/5x +5

Step-by-step explanation:

There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located.

The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.

The slope, the change in y divided by the change in x for two points, is ...

... (-1 -2)/(10 -5) = -3/5

This is the slope and the coefficient of x in the linear equation.

Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:

... y = mx + b

... y = (-3/5)x + 5

5.13 is larger. Because it is closer to a whole number. That’s what I believe it is at least. Forgive me if I am wrong

The function f(x) describes a parabola that opens downward. The only graph with that shape is the 2nd one.

_____

The degree of 2 on the x² term means there will be only 1 turning point (1 less than the degree). The bottom two choices have more turning points than that.

The minus sign on the coefficient of x² means the graph opens downward—that it tends toward -∞ when x gets very large in magnitude, either positive or negative.

The answer is 10 degrees since 90 - 80 = 10

the angle = 10°

Complementary angles sum to 90°

the complement of 80° is 90° - 80° = 10°
