9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?

$f(x) = 5x - 4$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(2a) = 5(2a) - 4$

$f(2a) = 10a - 4$

$156 = 10a - 4$

$10a - 4 = 156$

Add sides 4

$10a - 4 + 4 = 156 + 4$

$10a = 160$

Divide sides by 10

$\frac{10a}{10} = \frac{160}{10} \\$

$a = 16$

Complete the equation of the graphed linear function in point-slope form.

vazorg [7]

The point-slope form:
$y-y_1=m(x-x_1)$
m - slope
x₁, y₁ - the coordinates of a point

It passes through the points (1,-2) and (2,2).
$(1,-2) \\
x_1=1 \\ y_1=-2 \\ \\
(2,2) \\
x_2=2 \\ y_2=2 \\ \\
m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-1}=\frac{2+2}{1}=4$

$\boxed{y-(-2)=4(x-1)}$

From the given slopes of the lines, identify whether the two lines are parallel, perpendicular, or neither.

vivado [14]

Answer:

Neither

Step-by-step explanation:

To be parallel the lines have to have the same slope. In this case the slopes are not the same.

To be perpendicular, the lines have to have negative reciprocal slopes.

For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.

So, the lines are no parallel and no perpendicular.
