Answer:
- $70
- y = 25 + 0.9x
- $250
Step-by-step explanation:
1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be
$45 +25 = $70
2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...
y = 25 + 0.90x
3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.
If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.
x = 25 +0.9x . . . . . x is the spending level at which there is no advantage
0.1x = 25 . . . . . . . . subtract 0.9x
25/0.1 = x = 250 . . . divide by 0.1
Answer:
B
Step-by-step explanation:
y = 6(x^2-6x+9)-2
y = 6x^2-36x+54-2
y = 6x^2-36x+52
An equivalent exponent will produce the same result as the other exponent.
5^3 is equal to 125. The power can be rewritten to any equation that equals 3. One example is as follows:
The operation in parentheses is worked out first, so the exponent will stay equivalent to 5^3.
Answer:
triangle SAT is congruent to triangle SAO, because of SAS congruence criterion
given angle AST = angle ASO
ST = SO
SA = SA (common side)
therefore using the two sides and the angle included, triangle SAT congruent to triangle SAO.
