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}

If a town starts with population of 63,500 that declines by 700 people each year, construct an equation to model its population
ankoles [38]

The equation would be 63500-700x=P, where 63500 is the original population, -700 is the amount the population decreases each year, x is the number of years, and P is the total population.


To answer the second part of the question, plug in 53000 for P and solve for x:

63500-700x=53000

<em>*Subtract 63500 from both sides*</em>

-700x=-10500

<em>*Divide both sides by -700*</em>

x=15


It would take 15 years for the population to drop to 53000.


Hope this helps!!

Mr. Douglas drove 2,482 miles. He spent 42.5 hours in the car driving. What was his average speed for the trip?
riadik2000 [5.3K]

I think you just divide the number of miles by the number of hours he spent driving.

2,482/42.5= 58.4

58mph
