Y = 5 - 4x
5 - 4x = x^2 - 2x - 19
0 = x^2 + 2x -24
0 = (x + 6)(x - 4)
Therefore x = -6 (Given) or 4
x = 4, y = -9
(4,-9) is the other solution
Answer:
1. 7
2. 13
Step-by-step explanation:
<u>1. x = 2 and y = 3</u>
y^2 - x
= 3^2 - 2
= 9 - 2
= 7
<u>2. x = 5 and z = 4</u>
z + x + z
= 4 + 5 + 4
= 9 + 4
= 13
Answer:
EF is parallel to HG or EH is parallel to FG. EF to HG is correct I think.
Step-by-step explanation:
Look at the markings on the lines.
So for this system I will be applying the substitution method. Since y = -5x - 17, replace the y variable in the first equation with -5x - 17 and solve for x as such:
Now that we have the value for x, substitute it into either equation to solve for y:
<u>In short, x = -4 and y = 3.</u>
