For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>
Answer:
16 years
Step-by-step explanation:
Given that :
Earth's distance from sun = 93 million miles
Number of years to complete an orbit = 1 year
Average orbiting distance of new asteroid = 1488 million miles
Number of years to complete an orbit = x
93,000,000 Miles = 1
1488000000 miles = x
Cross multiply :
93000000x = 1488000000
x = 1488000000 / 93000000
x = 16 years
Period taken to orbit the sun = 16 years
Answer:Multiply the base area times the height to find the volume, which is the amount of packing material required
Step-by-step explanation: example :An empty box is shaped like a rectangular prism. The box has a base area of `9/10` square foot and a height of `1/3` foot. How much packing material is required to fill the box?
First, multiply the numerators, or the top numbers. 9 * 1 = 9
Then, multiply the denominators, or the bottom numbers. 10 * 3 = 30
So, the amount of packing material required is 9/30 cubic feet.
Answer:
y=-x+39
Step-by-step explanation:
to find the other factor you are going to need to divide the polynomial by the factor it gave
I do not have a pen and paper nearby to explain how to divide polynomials but if you leave a comment saying you don't know how I will explain it to you.
after dividing you get the answer x+2
