Answer:
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the equation in point slope form
From the graph, we have the following points;
[tex](x_1,y_1) = (-400,-400)[/tex]
[tex](x_2,y_2) = (100,-500)[/tex]
First, we calculate the slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-500 - (-400)}{100- (-400)}[/tex]
[tex]m = \frac{-500 +400}{100+400}[/tex]
[tex]m = \frac{-100}{500}[/tex]
[tex]m = -\frac{1}{5}[/tex]
The equation is then calculated using:
[tex]y - y_2 = m(x - x_2)[/tex]
Substitute x and y values
[tex]y - (-500) = -\frac{1}{5}(x - (100))[/tex]
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]

Answer:
I think x = 4
Step-by-step explanation:
x3 + -2x2 + -8x = 0
Reorder the terms:
-8x + -2x2 + x3 = 0
Solving
-8x + -2x2 + x3 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), 'x'.
x(-8 + -2x + x2) = 0
Factor a trinomial.
x((-2 + -1x)(4 + -1x)) = 0
Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:
Simplifying
x = 0
Solving
x = 0
Move all terms containing x to the left, all other terms to the right.
Simplifying
x = 0
Subproblem 2
Set the factor '(-2 + -1x)' equal to zero and attempt to solve:
Simplifying
-2 + -1x = 0
Solving
-2 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -1x = 0 + 2
Combine like terms: -2 + 2 = 0
0 + -1x = 0 + 2
-1x = 0 + 2
Combine like terms: 0 + 2 = 2
-1x = 2
Divide each side by '-1'.
x = -2
Simplifying
x = -2
Subproblem 3
Set the factor '(4 + -1x)' equal to zero and attempt to solve:
Simplifying
4 + -1x = 0
Solving
4 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + -1x = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -1x = 0 + -4
-1x = 0 + -4
Combine like terms: 0 + -4 = -4
-1x = -4
Divide each side by '-1'.
x = 4
Simplifying
x = 4

Match each function with the expression representing Its Inverse function.
1. g(x)= -0.5 x
2. h(x)= 4 x
3. y= x - 4
4. f(x)= x/2
5. k(x) = x
6. p(x) = x+4
Answers
Answer:
Step-by-step explanation:
1). g(x) = -0.5x
Equation form of the given function is,
y = -0.5x
Interchange x and y,
x = -0.5y
Solve for y,
y = [tex]-\frac{x}{0.5}[/tex]
y = -2x
Inverse function will be,
[tex]g^{-1}x=-2x[/tex]
2). h(x) = 4x
Equation form of the function will be,
y = 4x
Interchange x and y,
x = 4y
Solve for y,
y = [tex]\frac{x}{4}[/tex]
Inverse function will be,
[tex]h^{-1}(x)=0.25x[/tex]
3). y = x - 4
Interchange x and y,
x = y - 4
Solve for y,
y = x + 4
Therefore, inverse of the linear equation is,
y = x + 4
4). f(x) = [tex]\frac{x}{2}[/tex]
Equation form of the function will be,
y = [tex]\frac{x}{2}[/tex]= x
Interchange x and y,
x = [tex]\frac{y}{2}[/tex]
Solve for y,
y = 2x
Therefore, inverse function will be,
[tex]f^{-1}(x)=2x[/tex]
5). k(x) = x
Equation form of the function will be,
y = x
Interchange x and y,
x = y
Solve for y,
y = x
Inverse of the function 'f' will be,
[tex]k^{-1}(x) =x[/tex]
6). p(x) = x + 4
Equation form of the function will be,
y = x + 4
Interchange x and y,
x = y + 4
Solve for y,
y = x - 4
Inverse of the function 'p' will be,
[tex]p^{-1}(x)=x - 4[/tex]

Jess saved $500 working during the summer. He plans to buy school clothes with his money. He found jea
exactly twice as many shirts as jeans, how many pairs of jeans can Jess buy without exceeding $500?
Answers
Answer:
167 pairs
Step-by-step explanation:
Represent jeans with J and shirts with S
[tex]S = 2J[/tex]
[tex]Amount = \$500[/tex] --- Maximum
Required
Determine the number of pair of jeans he can buy
To represent as an inequality, we have:
[tex]S + J \leq Amount[/tex]
[tex]S + J \leq 500[/tex]
Substitute 2J for S
[tex]2J + J \leq 500[/tex]
[tex]3J \leq 500[/tex]
Divide through by 3
[tex]J \leq 500/3[/tex]
[tex]J \leq 167[/tex]
Hence, without exceeding $500, Jess can buy 167 pairs of jeans

The slope is the m in that form.
we will solve for y.
[tex]7x - 3y = 21 \\ \frac{- 7x \: \: \: \: \: \: = - 7x}{ - 3y = - 7x + 21} \\ \\ \frac{ - 3y}{ - 3} = \frac{ - 7x + 21}{ - 3} \\ y = \frac{7}{3} x - 7[/tex]
Answer:

-3y = -7x + 21
3y = 7x - 21

B. 5x2 - 6
C. 3x2 - 4
D. 5x2 - 4
Answers
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = (4x² + 1) + (x² - 5) = 5x² - 4. (D)
Answer:
D. 5x^2-4
Step-by-step explanation:
We are asked to find (f+g)(x), which is really just the sum of the two functions.
(f+g)(x)=f(x)+g(x)
We know the the functions are:
• f(x)= 4x^2+1
• g(x)=x^2-5
Substitute the functions in.
(f+g)(x)=(4x^2+1)+(x^2-5)
Add the functions by combining like terms. For this equation, the like terms are those with x^2 and the constants.
(f+g)(x)= (4x^2+x^2)+(1-5)
Add the terms with x^2
(f+g)(x)=(5x^2)+(1-5)
Add the constants or terms without variables.
(f+g)(x)=(5x^2)+(-4) = 5x^2-4
The sum of the functions is D. 5x^2-4
