Question

For f(x) = -5x + 4, what is the value of x for which f(x) = 29?

Your answer:

x = 1


x = -5


x = 5


x = -4

Answer 1

Answer:

x=-5

Step-by-step explanation:

f(-5)=-5(-5)+4

*negative multiplied by a neative is a positive*

f(-5)=25+4

f(-5)=29

Answer 2

You can just plug in every number in to the formula unit you get 29 like this
F(x)=-5(1)+4= -1.
F(x)=-5(-5)+4= 29. ANSWER
F(x)=-5(5)+4= -21.
F(x)=-5(-4)+4= 24.

B.-5 is the answer
