Answer:
520% of 100 = 520
Step-by-step explanation:
here, let the number be x
x = (520/100) × 100 (since % means-divide by 100)
x = 520
hence 520% of 100 is 520
Answer:
The y intercept is 200
Step-by-step explanation:
Given
Base Cost = 200
Per person =8
Required
Determine the y intercept
First, we need to determine the equation.
The total amount (y) for x persons can be calculated using:
y = Base Cost + Amount per person * x.
This gives
y = 200 + 8 * x
y = 200 + 8x
The general expression of a linear equation is:
y = mx + b
Where b = y intercept
By comparison,
b = 200
Hence, the y intercept is 200
Answer:
y = 1/4x^2 - 4.
Step-by-step explanation:
Vertex for is:
y = a(x - 0)^2 - 4 where a is a constant.
The graph passes through ( -8, 12) so substituting:
12 = a(-8)^2 - 4
12 = 64a - 4
64a = 16
a = 16/64 = 1/4.
So the equation is y = 1/4x^2 - 4.
