Its just simple
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
#12. When x = 4, y = 5(4) - 1 = 20 - 1 = 19
when x = 12, y = 5(12) - 1 = 60 - 1 = 59
when x = 0, y = 5(0) - 1 = 0 - 1 = -1
when x = 0.5, y = 5(0.5) - 1 = 2.5 - 1 = 1.5
First multiply both sides by 7
Your equation now looks like this:
x-28=0
Now move the constant to the other side causing it to change signs
The negative now becomes a positive
x=28
Now you are left with your answer:
x=28
Hope this helps! :3
The answer is 9x - 90y = 20.
Explanation:
y = 1/10 x - 2/9
First eliminate the fractions by multiplying through by the LCM which is 90:-
90y = 9x - 20
Standard form is ax + by = c, so rearranging we get:
0 = 9x - 90y - 20
9x - 90y = 20 .
