Write the slope-intercept form equation of the line that passes through (-2, 3) and (1,-4).
Answers
Answer:
y = -7/3 x -5/3
Step-by-step explanation:
We first need to find the slope
m = (y2-y1)/(x2-x1)
=(-4-3)/(1--2)
= (-4-3)/(1+2)
=-7/3
Slope intercept form of a line is
y=mx+b
y = -7/3x +b
Using the point (-2,3)
3 = -7/3(-2)+b
3 = 14/3 +b
Subtract 14/3 from each side
9/3 -14/3 =b

Twice one number added to another
number is 18. If the second number is equal
to 12 less than 4 times the first number, find
the two numbers.
First complete the equations below, where x stands for
the first number and y stands for the second number.
2x + y = 18; y = [?]x-[]
Answers
Answer:
The Answer is: The first number is 5 and the second one is 8.
please give me brainliest!! :)
Step-by-step explanation:
Let f = first number and s = second number
Twice the first number added to the second number is 18:
2f + s = 18
The second number is equal to 4 times the first number minus 12:
s = 4f - 12
Substitute:
2f + (4f - 12) = 18
6f - 12 = 18
6f = 18 + 12
6f = 30
f = 5, is the first number.
Solve for the 2nd number:
s = 4(5) - 12 = 20 - 12 = 8, is the second number.
Proof:
2f + s = 18
2(5) + 8 = 18
18 = 18
Hope this helps! Have an Awesome Day! :-)
Answer:
y = 8
x = 5
Step-by-step explanation:
This is a system of equations problem
Set up your two conditions:
2x + y = 18
y = 4x - 12
rearrange them to match
y = -2x + 18
y = 4x - 12
combine them by subtracting one equation from the other in such a way that it eliminates one variable. In this case I choose to subtract each value from the second equation from the first one
0 = -6x + 30
solve
6x = 30
x = 5
plug in the x value to solve for y
2(5) + y = 18
10 + y = 18
y = 8
Wilson is 6 years older than Mary. Wilson's age is 10 years less than five times Mary's age. The equations below model the relationship between Wilson's age (w) and Mary's age (m):
w = m + 6
w = 5m - 10
Which is a possible correct method to find Wilson's and Mary's ages?
Solve W + 6 = 5w - 10 to find the value of w.
Write the points where the graphs of the equations intersect the x axis.
Solve m + 6 = 5m - 10 to find the value of m.
Write the points where the graphs of the equations intersect the y axis.
Answers
Final answer:
The correct method to find Wilson's and Mary's ages with the given equations is to solve the equation m + 6 = 5m - 10 by substitution, which will give you the value of Mary's age (m). After finding m, you can then solve for Wilson's age (w).
Explanation:
Among the provided methods to find Wilson's and Mary's ages based on the given equations w = m + 6 and w = 5m - 10, the correct approach is to solve m + 6 = 5m - 10 to find the value of m, Mary's age. This is due to the fact that by substituting the expression for w from the first equation into the second, we isolate m and solve for it directly. Here is how you'd solve it step by step:
First, substitute w from the first equation into the second equation, resulting in m + 6 = 5m - 10.
Next, rearrange the terms to get all the m terms on one side: 5m - m = 10 + 6.
Then, simplify to find that 4m = 16.
Last, divide both sides by 4 to get m = 4.
Once you have m, substitute it back into either of the original equations to find w. In this case, w = 4 + 6 = 10.
Graphical solutions involving the x or y axis do not apply directly to solving the system of equations and are therefore not correct methods for this particular problem.
There are 18 offensive players on the hockey team. How many ways can the coach choose a left wing, center, and right wing to start the game?
Answers
Answer:
4896 ways
Step-by-step explanation:
We have a total of 18 players, and we want to form groups of three, where the order matters, because there are different roles for each player, so this is a permutation problem.
We solve this problem calculating a permutation of 18 choose 3:
P(18,3) = 18! / (18-3)! = 18! / 15! = 18 * 17 * 16 = 4896
So the coach has 4896 ways to choose the left wing, center and right wing.
Answer: There are 4,896 possible ways
Step-by-step explanation: If there are 18 offensive players on the hockey team, and there is a need to make a selection of three players for three different positions, that means each time you choose one player there is an 18 times 17 (18 x 17) other possibilities for the remaining players. If you choose the next player, there would now be a 17 times 16 (17 x 16) other possibilities for the remaining players, hence we need a formula for the arrangement of 3 players to be chosen from a total of 18.
From the first explanation, if we were to make an arrangement to choose all 18 players the permutation would be given as;
P = 18! (18 factorial)
Which is 18 x 17 x 16 x 15 x 14 x... x 1
However the permutation for selecting just 3 out of the 18 players is given as;
P = 18! ÷ 15!
And this results in;
P = 18 x 17 x 16
P= 4896
Therefore there are 4,896 possible ways
**Note that 18! divided by 15! leaves you with the possible arrangement for 3 persons which is explained as 18 x 17 x 16**

How long is ACACA, C?
Answer exactly, using a radical if needed.
Answers
The length of the side AC for the right triangle is 12√3 and the measure of angle C is equal to 30°.
The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.
The basic trigonometric ratios includes;
sine, cosine and tangent.
Considering angle 60 for the right triangle with side AC opposite it we get;
tan 60 = AC/12 {opposite side/adjacent side}
√3 = AC/12
AC = 12 × √3 {cross multiplication}
AC = 12√3
angle C = 180 - (60 + 90) {sum of interior angles of a triangle}
angle C = 180 - 150
angle C = 30°.
Therefore, using the tangent of angles 60 we have the side length AC to be 12√3 and the measure of angle C is 30°.

Suppose y varies directly with x. Write an equation if y=75when x=25
Answers
Answer:
y = 3x
Step-by-step explanation:
The standard format of a directly proportional equation goes by the format of y = k × x. The question asks us to write an equation if y = 75 when x = 25 and y varies directly with x.
So we substitute the values y = 75 and x = 25 in the equation y = k × x
K = constant, we have to work this out
75 = k × 25
75 ÷ 25 = k
k = 75 ÷ 25
k = 3
k = 3 So then we put this back into the original y = k × x to find our final equation which is y = 3x

Lance bought 12 quarts of lemonade so that everyone who came to his party could have exactly 1/3 quart. How many people did Lance invite to his party?
Answers
Lance invited 36 people to his party.
Step-by-step explanation:
It is given that,
Lance bought 12 quarts of lemonade.Everyone who came to his party could have exactly 1/3 quart.We know that,
The total quarts of lemonade available for the party = 12
Each person in the party consumes = 1/3 quart.
We need to find out how many people did Lance invited to his party.
To find the number of people :
Let us consider 'x' be the number of people invited to the party.
Total lemonade = number of people × lemonade for each person.
⇒ 12 = x × 1/3
⇒ 12×3 = x
⇒ x = 36 people
Therefore, Lance invited 36 people to his party.

A town has a population of 20000 and grows at 4% every year. To the nearest
year, how long will it be until the population will reach 39400?
Answers
Answer:
The population will reach 39,400 after 17 years.
Step-by-step explanation:
Given that, The population grows at a rate 4%. The population of the town is 20,000 at a certain time.
Exponential function:
[tex]y(t)=y_0(1+r)^t[/tex]
y(t) = The population after t years
[tex]y_0[/tex] = Initial population.
r = Rate of grow
t = Time.
y(t)= 39400, [tex]y_0[/tex] = 20,000, r= 4%=0.04, t=?
[tex]39400=20000(1+0.04)^t[/tex]
[tex]\Rightarrow \frac{39400}{20000}=(1.04)^t[/tex]
[tex]\Rightarrow \frac{197}{100}=(1.04)^t[/tex]
Taking ln both sides
[tex]\Rightarrow ln|\frac{197}{100}|=ln|(1.04)^t|[/tex]
[tex]\Rightarrow ln|\frac{197}{100}|=t\ ln|(1.04)|[/tex]
[tex]\Rightarrow t= \frac{ln|\frac{197}{100}|}{ln|(1.04)|}[/tex]
[tex]\Rightarrow t\approx 17[/tex]
The population will reach 39,400 after 17 years.
Final answer:
To find the time it takes for a town's population to grow from 20,000 to 39,400 at a 4% annual growth rate, the exponential growth formula is used. After rearranging the equation and taking natural logarithms, it's found that it will take approximately 18 years for the population to reach 39,400.
Explanation:
Population Growth Calculation
To calculate how long it will take for a town's population of 20,000 to grow to 39,400 with an annual growth rate of 4%, we can use the formula for exponential growth:
P(t) = P_0 × (1 + r)^t
where:
P(t) is the future population
P_0 is the initial population
r is the growth rate (expressed as a decimal)
t is the time period in years
Starting with 20,000 people and wanting to get to 39,400:
39400 = 20000 × (1 + 0.04)^t
To solve for t, we need to:
Rewrite the equation as: (1 + 0.04)^t = 39400 / 20000
Take the natural logarithm of both sides: ln((1 + 0.04)^t) = ln(39400 / 20000)
Simplify: t × ln(1 + 0.04) = ln(1.97)
Divide by ln(1 + 0.04) to isolate t: t = ln(1.97) / ln(1.04)
Use a calculator to find the numerical value for t.
When calculated, t is approximately 18 years. Therefore, it will take roughly 18 years for the town's population to grow from 20,000 to 39,400.
