Y=6x (1)
y=5x-7 (2)
Substitute y into (2)
(6x)=5x-7 -- subtract 5x from both sides
x=-7
Sub x into 1
y=6(-7)
y=-42
x=-7
y=-42
Answer:
c
Step-by-step explanation:
i just looked up the question
Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
= 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
= (25v - 2v)/25 dollars
= 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.
Answer:
The answer is: -0.5198
Step-by-step explanation:
CUBERT(8) – CUBERT(16) is the cube root of 8 - cube root of 16:
CubeRT(8) - CubeRT(16) =
2 - 2.5198 = -0.5198
Hope this helps! Have an Awesome day!! :-)
