Answer:
3
Step-by-step explanation:
company g is charging 10 per hour and in the graph when it is zero hours it shows the base charge which is 25 but in addition when you add an hour if you subtract that amount minus the flat amount 25 you will get 7 and will continue to do so as you continue across the graph 10-7 equals 3

Answer:
x/4+3
Step-by-step explanation:
Answer:
x=3 y=1
Step-by-step explanation:
x+y=4
y=-x+4
plug in the y
2x-(-x+4)=5
2x+x-4=5
3x=9
x=3
plug in x=3 into first equation to find y
y=-(3)+4
y=-3+4
y=1
Answer:
<h2><em>
a) inverse property</em></h2><h2><em>
b) commutative property</em></h2>
Step-by-step explanation:
Property for Addition:
a + b = b + a - <em>commutative</em>
(a + b) + c = a + (b + c) - <em>associative</em>
a + (-a) = 0 - <em>inverse</em>
a + 0 = a - <em>identity</em>
<em></em>
We have:
a) 13 + (-13) = 0 → <em>inverse property</em>
b) (-12) + 16 = 16 + (-12) - <em>commutative property</em>
