Answer:
<h2>A. y = 5</h2>
Step-by-step explanation:
A horizontal line has an equation: y = a (a - any real number).
Each point on a horizontal line y = a, has coordinates (x, a) (x - any real number).
We have the point (-7, 5) → y = 5
Answer:
45hours
Step-by-step explanation:
Given
Mary month earnings to be R(x)=13x+155
Josies monthly earning is given as Q(x)=9x+335
If Josie and Mary work to earn the same salary, then R(x) = Q(x)
13x+155 = 9x+335
subtract 155 from both sides
13x+155-155 = 9x+335-155
13x = 9x+180
subtract 9x from both sides
13x-9x = 9x+180-9x
4x = 180
x = 180/4
x = 45
Since x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
The area is 3.2
The scale factor is 2/5
We know that the length is 4 so 4x2/5=8/5
8/5x2=16/5. 16/5=3.2

Answer:
credit gain by retailer is $2257.39
Step-by-step explanation:
Given data:
Retaile price 83 4/3 c or 84.33c
Let Discount rate 6/7
Discount amount = (6/7)% of 84.33 c = 0.7228 C
Net credit received = 84.33c - 0.7228c = 83.607c
Net credit received = 83.607 c
Item required = 2700
Total discount = 2700 × 83.0607 = 225739.44c
Total discount = $2257.39
credit received by retailer is $2257.39
