I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:

2(3x + 1) = 11 Divide by 2 on both sides

3x + 1 = $\frac{11}{2}$ [11/2 or 5.5] Subtract by 1 on both sides

$3x=\frac{11}{2}-\frac{2}{2}$ [make the denominator the same to combine fractions]

3x = $\frac{9}{2}$ Divide by 3 on both sides

x = $\frac{9}{6}=\frac{3}{2}$

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.
