Answer:
The inverse is -1/7(x+4)
Step-by-step explanation:
We have the function
y = -7x-4
To find the inverse, exchange x and y
x = -7y -4
Solve for y
Add 4 to each side
x+4 = -7y -4+4
x+4 = -7y
Divide each side by -7
-1/7(x+4) = -7y/-7
-1/7(x+4) = y
The inverse is -1/7(x+4)
The answer is B. Points F, C and D are collinear
Answer:f(3)=26,f(6)=215
Step-by-step explanation:
f(x)=3^x-1
f(3)=3^3-1
f(3)=3x3x3-1
f(3)=27-1
f(3)=26
f(6)=6^3-1
f(6)=6x6x6-1
f(6)=216-1
f(6)=215
