Answer:
y = 5x + 18.......[1]
y = -6x - 15......[2]
equating equation 1&2 we get
5x+18=-6x-15
5x+6x=-15-18
11x=-33
x=-33/11=-3
x=-3
again
y=5×-3+18=-15+18=3
so,x=-3,y=3
Answer:
<u>The original price of the pants is US$ 19.oo</u>
Step-by-step explanation:
1. Let's check the information given to us to answer the question correctly:
Discount on pants = 20%
Price after the discount is applied and before taxes = $ 15.20
2. What is the original price of the pants?
For calculating the original price of the pants, we will use the Rule of Three Simple, this way:
x = original price of the pants
x * 0.8 = 15.20 * 1
x = 15.20/0.8
x = 19
<u>The original price of the pants is US$ 19.oo</u>
Answer: (-8, -80)
<u>Step-by-step explanation:</u>
y = 10x
y = -3x - 104
Substitute "y" with "10x" into the second equation, then solve for x:
10x = -3x - 104
13x = -104 <em>added 3x to both sides</em>
x = -8 <em>divided both sides by 13</em>
Next, substitute -8 for x into the first equation to solve for y:
y = 10(-8)
= -80
Answer:
Maximum of 14 Hours
Step-by-step explanation:
1500 + h(250) ≤ 5000
1500 + 250h ≤ 5000
250h ≤ 5000 - 1500
250h ≤ 3500
250h/250 ≤ 3500/250
h ≤ 14
