Answer:
y = -1/2x + (-1)
Step-by-step explanation:
Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
x^2-2x-13
Step-by-step explanation:
f(x) = 2x-5
g(x) = x^2 -4x-8
f(x) +g(x) = 2x-5 + x^2 -4x-8
Combine like terms
= x^2+2x-4x-5-8
=x^2-2x-13
Answer: x = -3 y = 2 So (-3,2)
Step-by-step explanation:
- x + 3y = 9 Multiply everything by 2 then add to the second equation.
2x + 5y = 4
<u>-2x +6y =18 </u> then 2x-2x=0 Add the other terms and solve for y.
11y = 22 divide both sides by 11 yo get y = 2 Substitute that into either one and solve for x.
2x + 5y = 4
2x + 5(2) = 4
2x + 10 = 4 subtract 10 from both sides 2x = 4 -10
2x = -6 so divide both sides by 2 to get x = -3
