Answer:
Option 3.
Step-by-step explanation:
The given function is
where, x is number of coupon books.
We have to find the practical domain for the given function.
Domain : The set of input values is called domain.
It is given that Raul is selling coupon books. He started with 50 coupon books and has already won a prize for selling at least 10 coupon books.
The number of coupon books can not be a decimal or fraction value. It means the values of x are integers.
The value x is all integers from 10 to 50.
Hence, the correct option is 3.
Answer:
y = -2x + 16.
Step-by-step explanation:
We are given the slope and a point on the line, so
we use the point-slope form of a straight line:
y - y1 = m(x - x1)
Here gradient m = -2, x1 = 4 and y1 = 8 , so we have:
y - 8 = -2(x - 4)
y - 8 = -2x + 8
y = -2x + 16.
Answer:
Parallel
Step-by-step explanation:
Parallel lines have the same slope but different y-intercepts. If you multiply the top equation by 2, you get:
2(12x + 4y = 16)
24x + 8y = 32
This shows that both lines have the same slope, but then you find the y-intercepts, they are different:
1st equation y-int = 4
2nd equation y-int = 9/2 or 4.5
Answer: top right
Step-by-step explanation: in order to seperate p, we need to multiply each side by 6, as this will make the right side just p. Then, since we mutiplied by 6 on the right side, we multiply by 6 on the left side too, so we get 5.5*6
Answer:
for Lena
C = 3x C + 5x
for Patrick
C = 9x C = 10x
for total C = 12x + 15x
