It really depends on how precise you're going to get.
You could get away with only two parts, but to be really precise, you should probably divide it into twelve (12) parts, because 5/12 means five out of twelve parts, so its would be right on the fifth subdividing marker line.
Answer:
h² - 10h + <u>25</u>
Step-by-step explanation:
h² - 10h + _ → (h - 5)² = h² - 10h + 25
Answer:
y=2x-3
Step-by-step explanation:
First, find slope of the line.
You can do this by: -5-(-3)/-1-0
This simplifies to 2. So, slope is equal to 2.
y-intercept is already given, (0,-3).
So, equation is y=2x-3
Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5
3x - 3x + y = 5 - 3x
y = 5 - 3x
--------------------------------------------------------
4x + 2y = 20
4x + 2(5 - 3x) = 20
4x + 2(5) + 2(-3x) = 20
4x + 10 - 6x = 20
10 - 2x = 20
10 - 10 - 2x = 20 - 10
-2x = 10
-2x ÷ -2 = 10 ÷ -2
x = -5
--------------------------------------------------------
y = 5 - 3x
y = 5 - 3(-5)
y = 5 + 15
y = 20
Your answer is x² + 4x - 4
