Answer:
read below
Step-by-step explanation:
so a proportional relationship does not have y-intercepts (ex.: starting price...)
<em>"a small pizza costs $9 and each additional topping costs $.75"</em> is not proportional because it does not start at 0.
<em>"a student earns $12 for each hour she tutors"</em> for example, is proportional because it does start at 0 and does not have anything added to it.
<u>proportional: y = mx</u>
<u>not proportional: y = mx + b</u>
299.99 * 0.35 = 104.9965
round to 105.00
299.99 - 105.00 = $194.99 sale price
Answer:
15.63 cm
literally all you need to do is substitute s for 2.5 which then is 2.5^3 which that simplified is 15.63 rounded to the nearest hundreth
Answer: No Solution
Step-by-step explanation:
y=2x+1 and 2x-y=3
Substitute y=2x+1 into 2x-y=3
So you will have: 2x-2x+1=3
Then,
2x-2x=0
0+1=3
1=3
1 doesn't equal 3 so there is no solution.
