Answer:
Step-by-step explanation:
The cost of each plan (y) is the sum of the initial fee and the product of the mileage charge and the number of miles (x).
First Plan: y = 40 +0.13x
Second Plan: y = 53 +0.08x
__
We can find when the costs are the same by solving this system of equations. A way to do that is to subtract the second equation from the first:
(y) -(y) = (40 +0.13x) -(53 +0.08x)
0 = -13 +0.05x
Multiplying by 20 gives ...
0 = -260 +x
Adding 260, we have ...
x = 260
The plans cost the same for 260 miles of driving.
__
The cost of the plans for that distance is ...
y = 40 +0.13x = 40 +0.13(260) = 40 +33.80
y = 73.80
The cost when the two plans cost the same is $73.80.
Answer:
They must meet at least three requirements like those in the explanation.
Step-by-step explanation:
-The other angles are also corresponding for example: B is congruent to E and C to F.
-
Its sides are proportional to each other
-These two triangles can have the same shape no matter what size each one is
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
