Answer:
The integers are 4 and 7 or -2 and 1.
Step-by-step explanation:
You can make a system of equations with the description of the two integers.
1. x = y + 3
2. 2x + 2 = y^2
The simplest and the fastest way to solve this system in this case is substitution. You can substitute x for y + 3 in the second equation.
1. x = y + 3
2. 2(y + 3) + 2 = y^2
Now simplify and solve the second one. For convenience, I will just disregard the first equation for now.
2y + 6 + 2 = y^2
y^2 - 2y - 8 = 0
You can factor this equation to solve for y.
(y - 4) (y + 2) = 0
y = 4, y = -2
Now we can substitute the value of y for x in the first equation.
x = 7, x = 1
16 yards will cost $199.84 assuming there is no tax. We know this because
12.49 X 16 = 199.84
2x - 3y = 6
-3y = 6 - 2x
y = -2 + 2/3x
2/3 times x-4 = 6
thats the answer :)
2x^2+7x-5+(-8x^2-3x+5)=-6x^2+4x.
