Answer:
4.00
Step-by-step explanation:
Given
x: 2 , 5 , 8 , 12
y: 8.50, 15.25, 22.00. 31.00
Required
Determine the y intercept
First, we calculate the slope:

Where





Next, we calculate the equation:

Where:

The equation becomes:


Make y the subject


Take
; to get the y intercept


<em>Hence, the y intercept is 4.00</em>
3x-5=x+55 (corr angle //line)
3x-x=55+5
2x=60
x=30
Answer:
f(x) = 7
Step-by-step explanation:
In an even function of x, all powers of x are even (2, 4, 6, etc.).
In this case we have f(x) = 7, or 7x^0, which is an even function because the power (0) of x is even.
Answer:
yes your eqation is correct...
