Answer: a) y=0.50x+15
b) The graph of this equation form on a coordinate plane is a line.
c) Slope =0.50 and y-intercept = 15
Step-by-step explanation:
Let x = Number of miles driven by car
Given: The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.
a) Total cost = 0.50x+15
If y =total cost of renting the car, then y=0.50x+15 (i)
b) Above equation is similar to y= mx+c (ii) [m = slope , xc=y-intercept] which a linear equation .
So the graph of this equation form on a coordinate plane is a line.
c) Comparing (i) and (ii)
m=0.50 , c=15
Slope =0.50 and y-intercept = 15
Circumference: 12 π
2 r π = 12 π
r = 12 π : 2 π
r = 6 cm, h = 6 : 2 = 3 cm
The total surface area of the cylinder:
S A = 2 · r² π + 2 r h π =
= 2 · 6² π + 2 · 6 · 3 π = 72 π + 36 π = 108 π cm²
Answer: The total surface is 108 π cm².
Sub in 2x + 3 for y in the first equation
2x - (2x + 3) = 7...now distribute the - through the parenthesis
2x - 2x - 3 = 7 ...add 7 to both sides
2x - 2x = 7 + 3
0 = 10 (incorrect)
This system has no solution....that is because the lines are parallel and will never intersect
