Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
Answer:
15% of $68 is $10.2
$68 + $10.2 = $78.2
The retail price is $78.20
The answer is F(x) = 900x + 600
Let x stands for the number of months
The apartment is rented for $900 a month, so every month it will be paid 900x (for example, for one month (x = 1), you will pay 900 · 1 = $900, for three months (x = 5), you will pay 900 · 5 = $4500, etc.)
A security deposit is paid only once and is not dependent on the number of months. So, its value is only 600.
These two values must be summed up because both must be paid, nothing is to subtract. Therefore, the function f(x) for apartments that rent for $900 a month and a security deposit of $600 is:
f(x) = 900x + 600
Answer:
I think it’s 24 oil changes
Step-by-step explanation:
If he can do 6 oil changes in 2 hours
8 divided by 2 is 4
And 4 x 6 is 24
