Answer:
Part A: $21 Part B: $30.21
Step-by-step explanation:
Part A: First, just multiply 15 to 40 divided by 100. 15 x 40/100
40/100= 0.4. 15 x 0.4=6. 15+6=$21
Part B: Discount the book by 25% and then add the sales tax which is 6% and then the answer would be $30.21.

Answer:
8
Step-by-step explanation:
y = (-3/4)x + c
Sub (11,-1) into the equtaion
-1 = (-3/4)(11) + c
c = 29/4
y = (-3/4)x + 29/4
when x = -1,
y = (-3/4)(-1) + 29/4
y = 8
r = 8
Answer:
correct
Step-by-step explanation:
H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4
