60 word 60second
? word 630 second
?=630
Answer:
The answer is y=4x+14 or C)
Step-by-step explanation:
m=slope To find equation of the line you need to do m=1+3/-3+4 m=4 y-y1=m(x-x1) y+3=4(x+4) y+3=4x+16 y=4x+13
A.
Cars Amount
0 cars $-117.50
1 car $-113.50
2 cars $-109.50
3 cars $-106.50
4 cars $-102.50
10 cars $-77.50
50 cars $82.50
100 cars $282.50
I do not know what graph you have but, you can see how much money you will make because it will form a straight line on the graph. As long as you continue the line, you will be able to see how many cars you have to clean to make a certain amount of money. Same is for the table.
B.
The change in the amount of money earned with each car is $4.00
The change on the graph is shown by the increasing slope.
C.
The number of cars that need to be washed can be seen by using the formula y=4x-117.5
The information from part a and b is used to show that there is a constant change (slope) and that more money is made by washing more cars.
3. The members need to wash 30 cars (rounded up from 29.375) to break even.
4. The members would have to wash 249 cars (rounded from 248.125) to fund their Washington trip.
The members would have to wash 117 cars (116.875) to fund their Valentine's Day Dance.
5. They would have to wash 366 cars.
Realistic
This can be realistic if there are a lot of members in the Math Club and if they set up in a good location. It will be successful.
Not Realistic
This is not realistic because there are many other factors that need to be taken into consideration. There might not be enough cars or people that are willing to get their car cleaned by these students. There are other supplies that they might need to buy and more.
Answer:
4.5
Step-by-step explanation:
3^2=9
1/2*9=4.5
What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
