Answer:
y>=2x-2
Step-by-step explanation:
You're gonna want to make one side equal to zero so subtract 8 from both sides
8x-4y-8 ≤0
Then you want to move the x and the constant back over by adding (-8x+8)
-4y ≤-8x+8
Then you'd flip the inequality sign and divide both sides by 4
y>=(8/4)x-(8/4)
Then you'd break the big numbers and make them exponents
y>=(2^3/2^2)x-(2^3/2^2)
Then you reduce the fraction by removing what appears in the numerator and denominator which in this case is 2^2
So your answer is: y>=2x-2
X = −19.30434782608696

Answer:
A the system has no solution
Step-by-step explanation:
Simplifying 2x + -5y = -8
Solving 2x + -5y = -8
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation. 2x + -5y + 5y = -8 + 5y
Combine like terms: -5y + 5y = 0 2x + 0 = -8 + 5y 2x = -8 + 5y
Divide each side by '2'. x = -4 + 2.5y Simplifying x = -4 + 2.5y
Solution for 2x-5=12 equation:
2x - 5 = 12
2x = 12 + 5
2x = 17 (divide both sides by 2 to get x)
2x/2 = 17/2
x = 8.5
This is a parabola by the looks of the equation and the fact that it's a satellite dish. The vertex of the equation is (-6,0) and the focus is 2/4, 1/2. 1/2 plus -6 is -5.5. the focus is (-5.5,0).
This answer is only true if the actual equation is y^2 not 2y
