Answer:
4√5, -4√5
Step-by-step explanation:
x^2 = 80
√x^2 = √80
x = 8.9 or 4√5
Answer:
x = 9
Step-by-step explanation:
y = 2/3x - 6
If the y point is 0, then plug that number into the equation and solve for x.
0 = 2/3x - 6
Add 6 to both sides of the equation.
6 + 0 = 2/3x - 6 + 6 or 6 = 2/3x
Multiply both sides by 3.
3 x 6 = 2/3x x 3 or 18 = 2x
Divide both sides by 2
18/2 = 2x / 2 or 9 = x
To find z, you have to divide -3 and 10, which you would get an odd number. That will be your answer for z :)
