<h3>
Answer: E. 7</h3>
=======================================================
Explanation:
Any point on the x axis always has its y coordinate equal to 0.
Plug in y = 0 and solve for x
y = 4x-28
0 = 4x-28
4x-28 = 0
4x = 28
x = 28/4
x = 7
Therefore, the point (7, 0) is on the line y = 4x-28 and also on the x axis. This is known as an x intercept.
Comparing (7, 0) this to (a, b) shows that a = 7 and b = 0.
as the exterior angle is known
sum of that angle and f angle = 180
142 + f = 180
f = 180 - 142
f = 38
Answer:
7
Step-by-step explanation:
x equals a certain number
3x - 2 = 19
add 2 both sides
3x=21
divide 3 both sides
x=7
It is 4 I believe sorry if I’m wrong
(2129-1727)/1727=0.232
The percentage of increase is 23%.
