<h2>Known : </h2>
y = -8x
4x - y = 3
<h2>Asked: </h2>
Use the substitution method to solve the system of equations ?
<h2>Answered:</h2>
<h3>Substitution y</h3>
4x - y = 3
4x - (-8x) = 3
4x + 8x = 3
12x = 3
x = 3/12
x = 1/4
<h3>
Substitution x</h3>
4x - y = 3
4(1/4) - y = 3
4/4 - y = 3
1 - y = 3
-y = 3 - 1
-y = 2
y = -2

Answer:
1660.75 square feet
Step-by-step explanation.
Width=<em>x</em>
Length =<em>x</em>+9
(<em>(</em><em>x</em><em>)</em><em>+</em><em>(</em><em>x</em><em>+</em><em>9</em><em>)</em>)×2=182 feet
(2x+9)×2=182
18+4x=164
x=36.5
Width=36.5 feet
Length=45.5 feet
Area=36.5×45.5
=1660.75 square feet
7.86*4.6=36.156

Answer:
275=27x+5
Step-by-step explanation:
10 people can go to the park
27(10)+5=275
The answer to that question will be 3
m = (y2-y1)/(x2-x1)
m = (6-4)/(4-0)
m = 2/4
y = mx + c
6 = (2/4)(4) + c
c = 4
Thus, the equation is y = (2/4)x +4
