-1

Step-by-step explanation:

2 - (-4) + (-y)

plug in 7 as y

2 - (-4) + (-7)

so you start with the first addition/subtraction (PEMDAS)

also the negative is distributed to the -4 make it positive, a negative and a negative equals a positive, therefore positive 4

2 - (-4) = 6

or

2 + 4 = 6

then... the equation reads

6 + (-7) = -1

*becareful -7 is "more than/ more negative than" 6 making the answer a negative

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
