10(7g-9h)-4h-8(-h+8g)
solve for g
7g + 8g since both are positive
15g
solve for h
9h+4h since both are negative
-14h
10-8 since the 8 is negative
12
12(15g-14h)
Since you typed the same equation twice I didn’t know if you meant to , so if it was meant to be doubled it would be
4(30g-28h)
Step-by-step explanation:
Given
f(x) = -5x - 1
and
g(x) = 2x + 2
Now
f(3) = - 5 * 3 - 1
= -15 -1
= -16
Also
g(-4) = 2 * (-4) + 2
= - 8 + 2
= - 6
To find the answer you must first make the equation which is
(5x)+85=150
subtract 85 from 150
(5x)=65
now divide 65 by 5
resulting in the answer
X=13
To check this
(5 x 13)+85=160
(5x)+85≤150
<h2><em>If you put and label the three points in a line, you will see that RS + ST = RT.
</em></h2><h2><em>
</em></h2><h2><em>Then you only need to substitue with the expressions given for RS and ST to find RT.
</em></h2><h2><em>
</em></h2><h2><em>RT = x +1 + 2x - 2 = 3x - 1
</em></h2><h2><em>
</em></h2><h2><em>Also, RT = 5x - 5
</em></h2><h2><em>
</em></h2><h2><em>Then, 3x - 1 = 5x - 5
</em></h2><h2><em>
</em></h2><h2><em>5x - 3x = 5 - 1
</em></h2><h2><em>
</em></h2><h2><em>2x = 4
</em></h2><h2><em>
</em></h2><h2><em>x = 4/2 = 2
