Step-by-step explanation:
X-intercept, y = 0
0 = -x² + 10x - 25
-x² + 10x - 25 = 0
-(x² - 10x + 25) = 0
x² - 10x + 25 = 0
(x - 5)(x - 5) = 0
x = 5
(5,0)
Answer:
Yellow: 50
Red: 25
Step-by-step explanation:
5:10
5 times 5 = 25
10 times 5 = 50
Answer:
Point slope form
Step-by-step explanation:
Given

Required
Determine the form of linear equation
A linear has just three forms:
1. The slope intercept form.: This is always in form of 
2. The point slope form: This is always in form of 
2. The standard form: This is always in form of 
<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>
Y = -(-2)^2 + 4(-2) + 1
y = -4 - 8 + 1
y = -11
