Answer:
1st equation (-1,-2) 2nd equation y= -12 which goes straight through x
Answer: choice C) -15x^4y
-----------------------------------------
Explanation:
The coefficients are -3 and 5. They are the numbers to the left of the variable terms
Multiply the coefficients to get -3*5 = -15. So -15 is the coefficient in the answer
Multiply the x terms to get x^3 times x = x^(3+1) = x^4. Notice the exponents are being added
Do the same for the y terms as well: y^2 times y^(-1) = y^(2+(-1)) = y^(2-1) = y^1 = y
So we have a final coefficient of -15, the x terms simplify to x^4 and the y terms simplify to just y
Put this all together and we end up with -15x^4y which is what choice C is showing
Answer:
Yes, the graph is proportional
Step-by-step explanation:
This graph is proportional because the origin (where the line starts) is at
(0, 0)

Answer:
(a) greater
Step-by-step explanation:
When comparing numbers, it is helpful to have them in the same form. You could express them both as fractions with the same denominator, as percentages, as decimals, or any other form you like.
walk to school: 18%
close to school: 11/50 = 22/100 = 22% . . . (greater than 18%)
The portion of students who live within 1/2 mile of school is greater than the portion who walk to school.
_____
<em>Additional comment</em>
The % symbol essentially means /100.
Then 18% = 18/100 = 9/50. The fraction 11/50 is greater than this.
