Answer:
x - intercept = - 9
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x
- 2x +
(0) = 18
- 2x + 0 = 18
- 2x = 18 ( divide both sides by - 2 )
x = - 9 or (- 9, 0 ) in coordinate form
Answer:
AC = 21, AB = 19, and BC = 22
Step-by-step explanation:
If x is the length of AC, then:
AB = x − 2
BC = x + 1
The perimeter is the sum of all three sides:
62 = x + x − 2 + x + 1
62 = 3x − 1
63 = 3x
x = 21
Therefore:
AC = 21, AB = 19, and BC = 22
