Answer:
i dont understand it
Step-by-step explanation:
Multiply by 100, as per cent means per 100.
30+x=42 I think because it's has to equal 42 and he already has 30
Answer:
line a and b are parallel
line c is not perpendicular because it is not 3
step-by-step explanation:
if the slope is the same it is parallel
if the slope is the complete opposite it is perpendicular
lines a and b are parallel with a slope of -1/3
(0, 5) (3, 4)
m = 4 - 5 / 3 - 0
m = -1 / 3
m = -1/3
(-1, 1) (2, 0)
m = 0 - 1 / 2 + 1
m = -1 / 3
m = -1/3
line c is perpendicular to lines a and b the slope is
(0, 0) (2, 5)
m = 5 - 0 / 2 - 0
m = 5/2
2.5

▹ Answer
<em>y = 15, -15</em>
▹ Step-by-Step Explanation
This is considered a 'square root' since we have to find y^2.
15 * 15 = 225
-15 * -15 = 225
Both of these values work for y, so the answer is 15, -15.
Hope this helps!
