How do i do 3=4(x-2)+5-3x

SashulF [63]

Answer:

6 = x

Step-by-step explanation:

first, we simplify the parenthesis by distributing the 4

3 = 4(x - 2) + 5 - 3x

3 = 4x - 8 + 5 - 3x

then, you add like terms

3 = x - 3

then add 3 to both sides to isolate x

6 = x

Does anyone know what f(x)=-5x-1 when f(-7) i need help with this please.

vodomira [7]

Answer:

f(-7) = 34

Step-by-step explanation:

If f(x) = -5x - 1, then . . .

f(x) = -5x - 1

f(-7) = -5(-7) - 1

= 35 - 1

= 34

. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.
