Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = (2x - 4)² ( take the square root of both sides )
= 2x - 4 ( add 4 to both sides )
+ 4 = 2x ( divide terms on both sides by 2 )
+ 2 = x
x = + 2
Change y back into terms of x
(x) =
+ 2, x ≥ 0
Answer:
Step-by-step explanation:
3 hours is equivalent to 180 minutes (found by multiplying the number of hours, 3, by the number of minutes in an hour, 60).
Therefore, the fraction of 3 hours that 25 minutes represents is , which can further be simplified to
.
Answer:
Step-by-step explanation:
y=-3x+13
y = mx + b, where m is the slope and b is the y-intercept.
A line parallel to this line will have the same slope, -3. We can start by writing:
y = -3x + b
No matter what is chosen for the value of b, this line will be parallel. We do want the line to go through point (6,10), however. The way that can be done is to find a value of b that would shift the line to go through (6,10).
Find b by entering the point (6,10) into the equation, and then solve for b:
y = -3x + b
10 = -3(6) + b
10 = -18 + b
b = 28
The line becomes y = 3x + 28
