What is the equation of a line passing through (-3,7) and having a slip of -1/5
MrRa [10]

Answer:

\large\boxed{D.\ y=-\dfrac{1}{5}x+\dfrac{32}{5}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the slope m = -1/5. Substitute:

y=-\dfrac{1}{5}x+b

Put the coordinates of the given point (-3, 7) to the equation:

7=-\dfrac{1}{5}(-3)+b

7=\dfrac{3}{5}+b            <em>subtract 3/5 from both sides</em>

6\dfrac{2}{5}=b\to b=\dfrac{6\cdot5+2}{5}=\dfrac{32}{5}

A family has two cars during one particular week the first car consume 25 gallons of gas and the second consumed 15 gallons of g
d1i1m1o1n [39]

Answer: the efficiency of the first car is 25 miles per gallon.

the efficiency of the second car is 30 miles per gallon.

Step-by-step explanation:

Let x represent the efficiency of the first car.

Let y represent the efficiency of the second car.

Distance = car efficiency × number of gallons.

The first car consume 25 gallons of gas and the second consumed 15 gallons of gas. The two cars Drove a combined total of 1075 miles. It means that

25x + 15y = 1075- - - - - - - - - - -1

The sum of the fuel efficiencies was 55 miles per gallon. It means that

x + y = 55

Substituting x = 55 - y into equation 1, it becomes

25(55 - y) + 15y = 1075

1375 - 25y + 15y = 1075

- 25y + 15y = 1075 - 1375

- 10y = - 300

y = - 300/-10

y = 30

x = 55 - y = 55 - 30

x = 25
