Step-by-step explanation:
Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
OA. $616
OB. $271
C. $332
D. $887
Answer:
Step-by-step explanation:
Payment per hour is $8
commission is 15%
Total number of hours worked for 2 weeks is 73 hours
Total sales=$2095
commission earned for 2 weeks:
15/100×2095
=$314.25
Total amount earned in 73 hours:
73×8=$584
Total amount earned in commission and wages:
584+314.25
=$898.25
Answer:
D

ANSWER: 15.5 units^2
Answer:
(4, 7 )
Step-by-step explanation:
given the 2 equations
3x - 8y + 44 = 0 → (1)
7x = 12y - 56 ( subtract 12y - 56 from bpth sides )
7x - 12y + 56 = 0 → (2)
multiplying (1) by 7 and (2) by - 3 and adding the result will eliminate x
21x - 56y + 308 = 0 → (3)
-21x + 36y - 168 = 0 → (4)
add (3) and (4) term by term to eliminate x
(21x - 21x) + (- 56y + 36y) + (308 - 168) = 0
0 - 20y + 140 = 0 ( subtract 140 from both sides )
- 20y = - 140 ( divide both sides by - 20 )
y = 7
substitute y = 7 into either of the 2 orinal equations and solve for x
substituting into (1)
3x - 8(7) + 44 = 0
3x - 56 + 44 = 0
3x - 12 = 0 ( add 12 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
solution is (4, 7 )
(5, 0)
(5, 0) and (–5, –80)
no solutions
Answer:
(5, 0 )
Step-by-step explanation:
Given the 2 equations
y = x² - 2x - 15 → (1)
y = 8x - 40 → (2)
Substitute y = x² - 2x - 15 into (2)
x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )
x² - 10x + 25 = 0 ← in standard form
(x - 5)² = 0 ← in factored form, thus
x - 5 = 0 ⇒ x = 5
Substitute x = 5 into (2) for corresponding value of y
y = 8(5) - 40 = 40 - 40 = 0
Solution is (5, 0 )
