Answer:
y intercept is -11
slope= -5/2
Step-by-step explanation:
slope is a negative one with points on x(-4.4) and x(-11)
4. 64/16 = 4. It drops 16 feet per second and 64 feet in total. It takes 4 seconds for a dropped object to fall 64 feet.
5. This one is a bit tricky, but the height would be 3. The formula would be 3 * 9 * 9. The width and length would both be 9. The height would be 3. 9 * 9 * 3 = 243. The volume of the rectangular prism would be 243 cubic centimeters.
6. Okay. Let’s see. 233 - 64 = 169. 169 squares is 13. The longest edge of the deck is 21 feet, because 13 + 8 = 21. Taylor will need 21 feet of railing for the longest edge of her deck.
First, figure out how many total cookies you need. You do this by multiplying the number of friends times the number of cookies each friend will get.
8 x 3 = 24
Then, you take the number of cookies and divide it by the number in each box to find the number of boxes you need.
24/6 = 4
Quan should get 4 boxes.
Answer:
Step-by-step explanation:
The number of months is our unknown, which we will call x. y is the amount she saves. Representing the fact that she puts $10 away per month is 10x. If she puts $300 down initially and then adds 10 per month to that, the first equation is
y = 10x + 300
The same goes for the second option. Putting $30 away every month is represented as 30x, and if she is starting with 100 and adding 30 a month to it, the second equation is
y = 30x + 100
We are being asked to find the number of months where the amount Tina saves is equal. Since y is the amount Tina has saved and we want to know when these amounts are equal, we will set the equations equal to each other and solve for x, the number of months.
10x + 300 = 30x + 100 and
200 = 20x so
x = 10. After 10 months, Tina will have saved the same amount of money regardless of which option she has chosen. This is only true for 10 months though. After that, one will show more of a savings than the other.
