I hope this helps you
1)
y=1+5/3
y=8/3
2)
-21a+16a=5a
3)
7a-9b
4)
5.x+5.10+x=6x+50
5)
5.-4n+7+2n=1
-20n+2n=1-7
-18n= -8
n=4/9
Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
Answer:
Step-by-step explanation:
First, we write the rental cost with each company:
Company A 
Company B 
Where m: miles travelled
Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:
Solving the equation for m by taking 0.2m and 60 on both sides:
Finally, dividing 0.5 on both sides:
From the table of values you can see the each y value is 3 times the x value.
This would be the slope of the line of graphed.
The equation is y = 3x
Answer:
The solutions the equation 1 are -1.3 and 2. The solutions to equation 2 are -1 and 0.
Step-by-step explanation:
Isolate the absolute value for equation 1. Then, set two equations equal to 5 and -5.
3x - 1 = 5 and 3x - 1 = -5
Solve for x in both and you would get -1.3 and 2.
Do the same for equation 2.
2x + 1 = -1 and 2x + 1 = 1
Solve for x and you would get -1 and 0.
