Answer:
The First one
Step-by-step explanation:
Just divide r/s and substitute x by 6.
A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
Express the line in slope intercept form
this is done by making y the subject.
y = 3x/2 + 4
slope is 3/2
product of perpendicular lines is negative one
let me slope of the other line
m * 3/2 = - 1
m = - 2/3
All you have to do is combine like terms here...all the x's and then all the constants. 2.3x + 2x -.2x = 4.1x; 14 + 15 = 29, so the perimeter is 4.1x + 29, A above.
