Answer:
answer is the 2nd one
Step-by-step explanation:
y = 1/3(3) - 1 = 1 - 1 = 0 (3,0)
y = 1/3(0) - 1 = 0 - 1 = -1 (0, -1)
y= 1/3(6) - 1 = 2 - 1 = 1 (6, 1)
Answer:
(-6,8)
Step-by-step explanation:
2x + 9y = 60
-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->
2x+ 81x + 558 = 60 -->
83x + 558 = 60 -->
83x = -498 -->
x = -6 -->
y = 9(-6) + 62 -->
y = 8
Answer:
$7.40
Step-by-step explanation:
Since both purchases cannot be paid for with $30, we assume the question refers only to the second purchase.
The cost of the 4 hamburgers is ...
4 × $5.65 = $22.60
Then the change from $30 is ...
$30.00 -22.60 = $7.40
Allie will receive $7.40 in change from the purchase of 4 hamburgers.
