Answer:

slope = \frac{1}{5}

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )

m = \frac{5-6}{4-9} = \frac{-1}{-5} = \frac{1}{5}

PLEASE HELP! is slope = undefined the same as y = 0?

An undefined slope is NOT the same as y= 0, since it is a vertical line. The x-coordinate never changes even if the y-coordinate is different. There is no run.

Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total o
xxTIMURxx [149]

Answer:

the volume of the gas used for city driving is 17 gallons

Step-by-step explanation:

Given;

average speed for city driving, v₁ = 17.1 miles per gallon

average speed for highway driving, v₂ = 24.7 miles per gallon

total distance traveled, d = 513 miles

total gallon of gas used, t = 26 gallons

Let the volume of gas used for city driving = x

Also, let the volume used for highway driving = y

x + y = 26 -------- (1)

17.1x + 24.7y = 513   ------------(2)

From equation (1); y = 26 - x

Substitute the value of y in equation (2)

17.1x   +   24.7(26-x)   =  513

17.1x   +   642.2   -    24.7x       =    513

17.1x  -  24.7x  =  513   -   642.2

-7.6x   = -129.2

x = 129.2/7.6

x = 17 gallons

Therefore, the volume of the gas used for city driving is 17 gallons
