You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
Answer:
f(-3) =16
Step-by-step explanation:
f(x) = -5x + 1
f(-3) means let x=-3
Substituting x=-3 into the equation
f(-3) = -5 (-3) +1
Multiplying -5 and -3
f(-3) = 15+1
f(-3) =16
Answer:
