What the answer for this ? :/
goblinko [34]
Hello there! I can help you! In order to answer those questions, we need to plug in the values, based off of the variable.

g. Okay. We are solving b - 10. b = -8. When you subtract something from a negative number, the number is even lower. Let's add the numbers first and then put in the negative symbol. 8 + 10 is 18. Put the negative sign and you get -18. The difference is -18.

h. Now, we solve a - b. a = 5 and b = -8. Because we are subtracting a negative number from a positive, we have to add both numbers, which means the number gets bigger. Ignore the negative sign and add. 5 + 8 is 13. There. The sum is 13.

i. The problem is c - a. c = -9 and a = 5. So as explained on problem G, for this problem, ignore the negative symbol and add. 9 + 5 is 14. Plug in the negative sign to get -14. There. The difference is -14.

PLEASE HELP ASAP! i don't get it
Natali5045456 [20]

Answer:

0 - 20

1 -22

5 - 30

10 - 40

15 - 50

20 - 60

Step-by-step explanation:

The initial amount this equation is 20 so that is why at 0 shirts its still 20 dollars for the set up fee and 2 dollars per shirt. Now that we have this information we can actually make a linear equation

y = 2x + 20

y = the total cost

x = the number of shirts

All you have to do next is plug in the number of shirts to get the total cost

Example:   2(1) + 20 = y

2 + 20 = y

22 = y

Meaning for 1 shirt it would be 22 dollars in total
