Answer:
B ($905)
Step-by-step explanation:
Plug in $17 for the h value in the equation, and you get this:
c = 50 (17) + 55
c = 850 + 55
c = 905
So the answer is $905 for 17 hours of work (plus the service fee)
I'm not completely sure but if you think your friend is 15 miles from it and you are four miles from your friend and you are actually closer to the store you would 15-4=11 then add 2 more miles because that is the distance from the grocery store so you should get 13 miles from home.
Answer: ![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
Step-by-step explanation:
Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.
Then, x= Grade 3 computers +Grade 4 computers.
![\Rightarrow\ x=58+57=115](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%3D58%2B57%3D115)
And y = Total computers - x
![\Rightarrow\ y=178-115=63](https://tex.z-dn.net/?f=%5CRightarrow%5C%20y%3D178-115%3D63)
Therefore, The equations can be used to find how many computers the rest of the school has.
![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
Answer:
B) Y-intercept: (0,3), X-intercept: (4,0)
Step-by-step explanation:
x = 0 12y = 36-9x
12y = 36
y = 3 y intercept: (0,3)
y = 0 9x = 36 x = 4
x intercept: (4,0)
y =x+10
y =6x+30
substitute x+10 into the 2nd equation anywhere you see y
x+10 = 6x+30
subtract x from each side
x-x+10 = 6x-x+30
10 = 5x+30
subtract 30 from each side
10-30=5x+30-30
-20 = 5x
divide by 5 on each side
-20/5 =5x/5
-4=x
now solve for y
y=x+10
y = -4 +10
y=6
Answer: x=-4
y=6
or (-4,6)
3. y = -3x-6
6x+5y=-30
6x+5(-3x-6) =-30
5x-15x-30=-30
-20x-30=-30
-20x=0
x=0
y = -3x-6
y=-6
