To find the x-intercept what you do is you plug in zero for Y:
0=4x-8
Then you would add 8 to the left side and x =2
Answer:
See a solution process below:
Explanation:
Let's call the number of miles driven we are looking for
m
.
The the total cost of ownership for the first car model is:
12000
+
0.1
m
The the total cost of ownership for the second car model is:
14000
+
0.08
m
We can equate these two expressions and solve for
m
to find after how many miles the total cost of ownership is the same:
12000
+
0.1
m
=
14000
+
0.08
m
Next, we can subtract
12000
and
0.08
m
from each side of the equation to isolate the
m
term while keeping the equation balanced:
−
12000
+
12000
+
0.1
m
−
0.08
m
=
−
12000
+
14000
+
0.08
m
−
0.08
m
0
+
(
0.1
−
0.08
)
m
=
2000
+
0
0.02
m
=
2000
Now, we can divide each side of the equation by
0.02
to solve for
m
while keeping the equation balanced:
0.02
m
0.02
=
2000
0.02
0.02
m
0.02
=
100000
After 100,000 miles the total cost of ownership of the two cars would be the same.
Answer:
(2 , 72) and (5 , 180)
Step-by-step explanation:
when x = 2 , y = 36× 2 = 72 (2,72)
when x = 4 , y = 36×4 = 180 (4,180)
Answer:
no
Step-by-step explanation:
the FIRST 82 RUNNERS does not accurately represent the last or the middle placed runners to finish
Answer:
The second blank, which is the exponent on the y there, is -3.
Step-by-step explanation:
implies 
since 3(4)=12.
implies 
.
can be solved by subtracting 5 on both sides. This gives you:
Let's put it altogether:
So the first blank is 4.
The second blank, which is the exponent on the y there, is -3.
