Answer:
See below
Step-by-step explanation:
Remember that y=mx+b:
1) y = -3x+7
2) y = 1/4x-5
Answer:
They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.
Starry Crown charges (138 dollars)/(4 hours) = (138/4 dollars)/hour = (34.50 dollars)/hour
Solar R Us charges (143 dollars)/(5 hours) = (143/5 dollars)/hour = (28.60 dollars)/hour
Lights On Us charged (157 dollars)/(6 hours) = (157/6 dollars)/hour = (27.17 dollars)/hour
Lights On Us has the best rate.
In order to figure this out, you are going to do the math backwards. If the perimeter of the entire field is 96 meters, you will want to remove 16, which will give you 80 meters. You will then divide this by 2, giving you 40 meters. The width of the field will be 40 meters. That means that the length of the field is going to be 56 meters.
