<u>The system of equation</u>
First equation
x = 2y + 7
Second equation
3x - 2y = 3
<u>Substitute x with (2y + 7) in the second equation</u>
3x - 2y = 3
3(2y + 7) - 2y = 3
use distributive property
3(2y) + 3(7) - 2y = 3
6y + 21 - 2y = 3
add like terms
6y - 2y + 21 = 3
4y = 3 - 21
4y = -18
y = -18/4
y = -4.5
<u>Substitute y with its value, which is -4.5, in the first equation</u>
x = 2y + 7
x = 2(-4.5) + 7
x = -9 + 7
x = -2
<u>The solution is</u>
<u />(x,y) = (-2, -4.5)
3.30 x 5 = 16.50
4.30 x 7 = 30.10
30.10 + 16.50 = $46.60
Period For Interest = 9 months
Period taken = 54 months
Investment = 2000
Quarters for payment = 54 ÷ 9
=6 periods
2000×2 = 4000
4000×2 = 8000
8000×2 = 16000
16000×2 = 32000
32000×2 = 64000
64000×2 = 128000
Answer = 128000
Answer:
48 degrees
Step-by-step explanation:
A triangle has three angles that add up to 180 degrees. In a right triangle, one of the angles in 90 degress, and the other 2 add up to 90. In this case, we have 2 given angles, 90 degree angle and 42 degree angle. If we do 90+42 it gives us 132. We then subtract that from 180 to give us 48 degrees.
A binomial is an expression that has two terms.
(1) Has a single term
(2) Has two terms
(3) Has three terms
(4) Has a single term
So the only binomial out of the answers is (3)
