Draw a dot at -8 on the graph
Then draw a dotted line across the graph, going through the -8 dot
Then highlight the part on top of the line
^^Reason: Y is GREATER than -8, so all y possibilities are going to be greater than -8
The number of cars that have passed through the intersection after 7 wrecks is 1/5 cars
<h3>Direct variation</h3><h3 />
- Number of wrecks = w
- Number of cars = c
w = k × c
31 = k × 1,085
31 = 1,085k
k = 1085/31
k = 35
If w = 7
w = k × c
7 = 35 × c
7 = 35c
c = 7/35
c = 1/5 car

The two numbers are 709 and 28,360
X + x + 2 = 90
2x + 2 = 90
-2. -2
to combine like terms
2x = 88
Divide both sides by 2 to isolate x
x = 44
Answer
A is x+2 = 46
B is x = 44
Total 90 degrees = complementary angle
