Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?

irina1246 [14]

Answer:

$x=\frac{16}{5}$

Step-by-step explanation:

The given function is

$f(x) = -5x +1+3$

Which can be rewritten also as

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

We want to find the values of x for which

$f(x) = -12$

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

$-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}$

Write the equation of a line in slope-intercept form from the graph below. tytyty

Leya [2.2K]

Answer:

y = x.

Step-by-step explanation:

From the graph we see that the line passes through the origin (0, 0) and the point (8,8), so the slope is (8-0) / (8-0) = 1.

The y intercept is at (0.0).

y =- mx + c is the slope intercept form so m = 1 and c = 0 and the answer is

y = 1x + 0

y = x.

Eight equals r to the power of two

Tasya [4]

Answer:

r= $2\sqrt{2}$

r= - $2\sqrt{2}$

Step-by-step explanation:

8= $r^{2}$

Square root both sides of the equation.

r= $2\sqrt{2}$

r= - $2\sqrt{2}$
