X AND Y INTERCEPTS
1st Answer:
x = 9
Step-by-step explanation:
first you want to substitute the y
0 = -2 √(25 - x + 8)
move the expression to the left
2 √(25 - x) = 8
divide both sides
√25 - x + 4
move the constant to the right
25 - x = 16
calculate
-x = -9
change the signs
x = 9
2nd Answer:
x = -65/9 OR x = - 7 2/9, x = - 7.2
Step-by-step explanation:
first you want to substitute the y
0 = -3 √(x + 9) = 4
move the expression to the left
3√(x+9) = 4
divide both sides
√(x+9) = 4/3
move the constant to the right
x = 16/9 - 9
calculate
x = -65/9
