Answer:
Step-by-step explanation:
Original cost = $32
Discount = 30% of 32
Selling price = 32 - 9.60 = $22.40
Tax = 6.75% of 22.40
= $ 1.51
Total cost with discount and tax = 22.40 - 1.51 = $ 20.89

Answer:
42+7xy=(7*6)+(7xy).......
If you begin with the basic equation of a vertical parabola: y-k=a(x-h)^2, where (h,k) is the vertex, then that equation, when the vertex is (-3,-2), is
y + 2 = a (x + 3)^2. If we solve this for y, we get
y = a(x+3)^2 - 2. Thus, eliminate answers A and D. That leaves B, since B correctly shows (x+3)^2.
Answer:
Step-by-step explanation:
divide by 2 and square it
y+axSQUARED +bx+ c ----->(b/2)squared +d
2 ) add and subtract d to the equation
y = (axSQUARED +bx +d ) + c -d
factor the first part of the equation to match the vertex form and simplify
y= a(x-h)SQUARED + c- d
Y = a ( x - h SQUARED + k
