Answer:
A. {4,3}
Step-by-step explanation:
x -2y = -2
y = - 3x +15
x - 2(-3x+15) = -2
x +6x - 30 = -2
7x = 28
x = 4
y = - 3x +15 = - 3*4 + 15 = -12 + 15 = 3
{4,3}
Okay okay okay
Answer:
r = 
Step-by-step explanation:
12 -
= 5
6 × 12 × r × 6 -
= 5 × 6
72r - r = 30
71r = 30
r = 30 ÷ 71
r = 
Hi, there.
For this question, we can apply the Pythagorean theorem
.
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in
is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c: 
Plug in the value for s:

Do the innermost exponents first:

The square root symbol and the power of 2 cancel each other out, so we are left with:
s =
, so the hypotenuse is 4608 inches.
Not proportional hope that helps
