Answer:(f*g)(x)= 21x^2 -29x -10
Step-by-step explanation:
(3x-5)(7x+2)
21x^2-35x+6x-10
21x^2-29x-10
<em>Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.</em>
<em>Thus, I am solving based on it. It would still clear your concept. </em>
Answer:
The inverse of f(x)=9x+7
Step-by-step explanation:
Given the function

A function g is the inverse of function f if for y=f(x), x=g(y)
Replace x with y

solve for y


Therefore,
The inverse of f(x)=9x+7 is:
i.e.

A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
Answer:
Y= -3/5x - 3
Step-by-step explanation:
3x+5y=-15
-3x. -3x
5y=-3x-15 then you would divide 5 from all the numbers to get : y=-3/5x-3.
