Answer:
With all the lines, I may be wrong. But I'm confident that line B has a slope of 2.
This is because it rises up 2 up the y axis for every one unit on the x axis.
Answer: d1 is 50, c2 is 21/25
The answer is 272 + 102 which equals 374yd^2
Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11
Make the same denominator then Add which would be 4/12 + 1/12 which is 5/12
