First is to make equations for both sides.
Let x be the number of the miles.
a be the charge of the first company
b be the charge of the second
a=$35+$0.25(x), b=$40+$0.20(x) .
then a=b
Substitute the equations
$35+$0.25(x)=$40+$0.20(x)
$0.25x - $0.20x = $40 - $35
$0.05x = $5
x= $5/$0.05 , cancel out the unit.
x= 100
To justify substitute x to both the equations a and b.
a= 35 + 0.25(x)
a= 35 + 0.25(100)
a= 35 + 25
a= $60
b= 40 + 0.20(x)
b= 40 + 0.20(100)
b= 40 + 20
b= 60
a=b
60=60.
Answer:
y=-x+1
Step-by-step explanation:
The slope is -1. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y--1)=-1(x-2)
y+1=-x+2
y=-x+1
Answer:
j(x) = 36 x - 60
Step-by-step explanation:
Here, the given functions are:
k(x) = 12
and m(x) = 3x - 3
Now, we need to find the expression for j(x) = k(x) * m(x)
By DISTRIBUTIVE PROPERTY:
A(B-C) = AB - AC
or, k(x) * m(x) = 36x - 60
Hence, j(x) = 36 x - 60
