The total to this would be $1,389.93 because $1,299 + 7% = $1,389.93
0.77 is the answer to your question
Answer:
y = -5/3x + 3
Step-by-step explanation:
First lets turn the equation from standard form to slope intercept form.
3x - 5y = 1
~Subtract 3x to both sides
-5y = 1 - 3x
~Divide -5 to everything
y = -1/5 + 3/5x
~Reorder
y = 3/5x - 1/5
Now that we have the equation in slope intercept form, we can find the new equation. A perpendicular line will have the opposite reciprocal of the original slope.
3/5x -> -5/3x
Now that we have the slope, we can use the given point to find the y-intercept.
y = -5/3x + b
8 = -5/3(-3) + b
8 = 5 + b
3 = b
Put all the information we solved for into a final equation.
y = -5/3x + 3
Best of Luck!
Answer:
y = 0.5x + 50.95
Step-by-step explanation:
Given y is total cost while x is total miles
Slope: m = (y2-y1)/(x2-x1)
m = (75.95-65.95)/(50-30) = 10/20 = 0.5
y = mx + b
y = 0.5x + b
75.95 = 0.5(50) + b
b = 50.95
Slope intercept form: y = 0.5x + 50.95
