Answer:
the answer of the complete equation is 0
Step-by-step explanation:
first you multiply by 2 all in the parenthesis, 2(15) and 2(3) you got a 30. Then you do the exponents 3(3) is 9
so you got like this= 30-6+9(4)
You multiply 9 and 4=
30-6+36
and the answer is 0
Answer:
x y
0 -1
-1 0
-8 7
Step-by-step explanation:
y = -x - 1
when x = 0, y = -1
when y = 0
0 = -x - 1
x = -1
when x = -8,
y = -(-8) - 1
y = 7

Answer:
15.5x - 300 >= 280
Step-by-step explanation:
Let x = the number of hours she works.
The amount of money she earns will be 15.50x
Her rent costs $300, so that value gets subtracted from the amount she earns. That makes our expression for how much money she earns:
15.5x - 300
This amount has to be over 280, so our inequality will be:
15.5x - 300 >= 280
So if 7 is the middle x-value, you calculate how far it is from the given endpoint in order to determine how far it is from the other endpoint. So,
7 -5 =2, so the other endpoint must be 2 away from 7 in the opposite direction, 7+2=9
Then repeat with y,
3-1/2=5/2, therefore 1/2 - 5/2 = -4/2= -2
So the point is (9, -2)
