Okay -
So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on <em>one </em>side of the equation!
<em>* original equation </em>
<em>5x + 4 = 49.
</em><em>* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
</em><em>5x + 4 - 4 = 49 - 4.
* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.
* and our answer is...
x = 9. =)

Answer:
A.
The y-intercept of m is less than the y-intercept of n.
Step-by-step explanation:
y-intercept of a function:
The y-intercept of a function is the value of y when 
Function n represents a cubic function that passes through the points (-1,0) and (0,2).
When
, and thus, the y-intercept is y = 2.
Function m:
When
, and thus, the y-intercept is y = -6, which is a smaller number than 2, so the y-intercept of m is less than the y-intercept of n, and the correct answer is given by option A.

Hi there! :)
Answer:

m∠BGC = 16x - 4
m∠CGD = 2x + 13
m∠BGC + m∠CGD sums up to 90°, therefore:
(16x - 4) + (2x + 13) = 90
Combine like terms and simplify:
16x + 2x - 4 + 13 = 90
18x - 4 + 13 = 90
18x + 9 = 90
18x = 81
18x/18 = 81/8
x = 4.5
