3x + 4y = -12
X - Intercept: 3x + 4y = -12
3x + 4(0) = -12
3x + 0 = -12
3x = -12
3 3
x = -4
(x, y) = (-4, 0)
Y - Intercept: 3x + 4y = 12
3(0) + 4y = 12
0 + 4y = 12
4y = 12
4 4
y = 3
(x, y) = (0, 3)

Step-by-step explanation:
Answer:
60
Step-by-Step Explanation:
(200-125):125*100 =
(200:125-1)*100 =
160-100 = 60
Now we have: What is the percentage increase/decrease from 125 to 200 = 60
Answer:
33cm
Step-by-step explanation:
385 / 35 = 11
11 times 3 = 33
Answer:
x = - 1 and x = 5
Step-by-step explanation:
Given
(x - 3)² + 2(x - 3) - 8 = 0
Let u = x - 3, then
u² + 2u - 8 = 0 ← solve for u
(u + 4)(u - 2) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 4 = 0 ⇒ u = - 4
u - 2 = 0 ⇒ u = 2
Convert back to x, that is
x - 3 = - 4 ( add 3 to both sides ) ⇒ x = - 1
x - 3 = 2 ( add 3 to both sides ) ⇒ x = 5
