Answer:
so
slope is calculated this way:

let's calculate y init by:
3 = -3×2 + b
b = 9
so equation is:
y=-3x+9
Answer:
(-00, 00)
Step-by-step explanation:
(-infinity, infinity)
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
4x^2 + 16x-2= 5x
Minus 16x over
4x2-2= -11x
Add 11x over
4x^2 +11x -2
Use quadratic formula x= 2.9
I’m not sure here. I tried my best. Hope it helps!
I think that the answer is 45% because the sale started off with a 20% discount, but at the end they added another 25% to the sales. So since the sale already started off with 20%, you add 20%+25% which equals 45%.
