We know the rate for sales tax is:
This means Cindy has to pay for the bouquet of roses and the bouquet of daisies plus the 
of the value of each item.
So, we have to calculate the sales tax for both items:
Hence:
Answer:
f(x) = -
(x-40
+48
Step-by-step explanation:
Assuming you typed this out right
a= -1/32 is the only way it can have a point of (60,36); I just plugged in numbers for the rest
All to one side:
4x^2-32x+64 = 0,
divide by 4:
x^2 -8x + 16 = 0
apply formula or see that it is (x-4)^2!, so only x =4 is a root and it is double.
Answer:
y= 5x+20
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
The slope is 5 and a point on the line is (-4,0)
Substituting this information into the equation, we can solve for b
0 = 5(-4) +b
0 = -20+b
Add 20 to each side
0+20 = -20+20+b
20 = b
y = 5x+20
