Answer:
for this you should use photomath all you do is take a picture of each problem and put the answer down
Answer:
B
Step-by-step explanation:
let f(x) = y and rearrange making x the subject
y = 
( multiply both sides by 7 to clear the fraction )
7y = x + 2 ( subtract 2 from both sides )
7y - 2 = x
Change y back into terms of x with x the inverse function, that is
p(x) = 7x - 2
Answer:
Step-by-step explanation: It's 34
Answer:x=2; second option
Step-by-step explanation:
120+10x=140
10x=20
X=2
You would multiply by -4/3. That's cuz to get to 1, you have to cancel out the negative, with another negative. You then have to multiply by the reciprocal.
Hope this helps!
