8.5 hours
T = 9 • h (hours worked)
$76.50 = 9 • h
76.50/9 = h
h = 8.5 hours
Answer:
A general line is written as:
y = a*x + b
where:
a is the slope
b is the y-intercept.
a) y-intercept = 2 and slope = 7.
This line is:
y = 7*x + 2
b) y-intercept = -1 and is parallel to y= 5x - 7.
Now, if two linear equations are parallel if they have the same slope and different y-intercept. Then if we want a line parallel to y= 5x - 7, this means that the slope of this line must also be equal to 5.
y = 5*x + (-1)
c) y-intercept 2 and is inclined at 45° to the x- axis.
When we have an inclination of A degrees from the x-axis, the slope of the equation is given by: a = Tan(A)
In this case, we have A = 45°
Then the slope is a = Tan(45°) = 1
Then the equation of this line is:
y = 1*x + 2
Basically, we need to find the lowest common multiple of 10 and 15.
that multiply would be 30. That means that the bells will ring together in 30 minutes.
So 30 minutes from 6 p.m. is 6:30 p.m. <==
It’s c
8 squared is 64
If you multiply that by 4 you will get 256 pi
You will not have to approximate it.
50. Slope- -1
Y intercept- (0,7)
51. Slope- -1/3
Y intercept- (0,-3)
