Answer:
Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:
#Subtracting equation 2 from 1:
Hence the fixed cost per mile driven,
is $0.20
To find the constant,
we substitute in any of the equations:
Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
Answer:
3 hours
Step-by-step explanation:
43-16=27
27/9=3
Answer:
The second and the third one
Step-by-step explanation:
Answer:
Step-by-step explanation:
81
=
3
4
and
27
=
3
3
, so this equation can also be written as
3
4
x
=
3
3
(
x
+
2
)
=
3
3
x
+
6
.
Since the bases are now the same, we can equate exponents to get
4
x
=
3
x
+
6
so that
x
=
6
(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).

Answer:
So is there are 10 cats for every 4 dogs,
If there are 5 cats that is half of 10 so half of 4 is 2
Now there are 32 dogs that is 8 times more than 4 so 10 x 4 is 40 so the answers are
Cats 10 5 8
Dogs 4 2 32
