Answer:
y=1/3x-3
Step-by-step explanation:
To find slope, use m=y1-y2/x2-x1. I did -4-(-3)/-3-0 to get 1/3. Then plug it and one of the points into y-y1=m(x-m1). y-(-4)=1/3(x-(9-3)). Simplify (isolate y) to get y=1/3x-3.
Answer:
-x^4y + x
Step-by-step explanation:
-2x^7y^2 + 2x^4y + 2x^3y
You can take out 2x^3y because there is enough of that in each part of the equation. Then you just divide the whole numbers and subtract the exponents.
-x^4y + x
Answer:
15x 12y=489
Step-by-step explanation:
In the problem it says that x is the number of adult shirts which 15 and y is the number for a youth shirt. So it would be 15x 12y. Hope this helped! :D

Answer:
2.85
Step-by-Step Explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
1.5% = 1.5 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
1.5% = 1.5/100 = 1.5 ÷ 100 = 0.015
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 1.5% of what number = 2.85?
1.5% of what number = 2.85
... is equivalent to:
1.5% × ? = 2.85
1.5% × ? = 2.85 =>
? =
2.85 ÷ 1.5% =
2.85 ÷ (1.5 ÷ 100) =
(100 × 2.85) ÷ 1.5 =
285 ÷ 1.5 =
190
1.5% of 190 = 2.85
If 1.5% × 190 = 2.85 =>
Divide 2.85 by 190...
... And see if we get as a result: 1.5%
Note:
Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.
Calculate the percent value:
2.85 ÷ 190 =
0.015 =
0.015 × 100/100 =
(0.015 × 100)/100 =
1.5/100 =
1.5%
So we have proven that the calculations are correct.
Answer:
1.5% of 190 = 2.85
