Answer:

$x=12$

Step-by-step explanation:

we know that

A linear pair is two angles that are adjacent and form a line. The angle measure of a line is 180 degrees

In this problem we have that

$(10x-20)^o+(6x+8)^o=180^o$ --- by supplementary angles (form a linear pair)

solve for x

$(16x-12)=180$

$16x=180+12$

$16x=192$

$x=12$

If (3, y) lies on the graph of y = -(2^x) then y=<br> 1/8<br> -6<br> -8

vazorg [7]

<h3>Answer is -8</h3>

Work Shown:

y = -(2^x)

y = -(2^3) ... replace x with 3

y = -(2*2*2) ... expand out 2 cubed

y = -8

Point R lies on the directed line segment from L (-8,-10) to M (4,-2) and partitions the segment in the ratio 3 to 5. What are t

Dvinal [7]

Answer:

R = (- 3.5, - 7 )

Step-by-step explanation:

Using the Section formula

$x_{R}$ = $\frac{3(4)+5(-8)}{3+5}$ = $\frac{12-40}{8}$ = $\frac{-28}{8}$ = - 3.5

$y_{R}$ = $\frac{3(-2)+5(-10)}{3+5}$ = $\frac{-6-50}{8}$ = $\frac{-56}{8}$ = - 7

Thus coordinates of R = (- 3.5, - 7 )
