-2x + 12 = 2y
Add 2x on both sides,
12 = 2y + 2x
Divide by 2 on both sides,
6 = y + x -> x + y = 6
The answer is D.
Answer:
b = 7
Step-by-step explanation:
- 4(2 - 5b) = 132
- 4 × 2 - 4 × (- 5b) = 132
-8 + 20b = 132
20b = 132 + 8
20b = 140
b = 140/20
b = 7
Thus, The value of b is 7

Given:
The equation of the parabola is:

To find:
The y-intercept of the parabola.
Solution:
We have,

Putting
in the given equation, we get



Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
Answer:
a = 9
Step-by-step explanation:
45 = 4(a + 3) – 3
Add 3 to both sides.
48 = 4(a + 3)
Divide both sides by 4.
12 = a + 3
Subtract 3 from both sides.
9 = a
a = 9
Answer: a = 9
