Answer:
I think it always work out because they try to manipulate the equation such that you'll get 3
you can actually use other values apart from the ones used
Answer:
3x-2y=-28
Step-by-step explanation:
Answer:
y = (2/5)x + 2
Step-by-step explanation:
To find the inverse of a function, we simply exchange the variables x and y and solve for y.
For this function we will write it as such:
y = -5 + (5/2)x
So to find the inverse, we will swap the x and y and solve.
y = -5 + (5/2)x
x = -5 + (5/2)y
x + 5 = (5/2)y
(2/5) * (x + 5) = y
(2/5)x + (2/5)5 = y
(2/5)x + 2 = y
Thus the inverse of the function is:
y = (2/5)x + 2

(x-1)(x^3+x^2+x+7) is your answer.
Answer:
y=4x+40
Step-by-step explanation:
slope equals 4
x-intercept= -10
y=mx+b for the x-intercept the y equals zero so plugging zero the y and -10 to the x
0=4(-10)+b
0=-40+b now you isolate the variables
b=40 so the equation is y=4x+40 because you have the slope you just pluggin the numbers to the equation
