Write the equation of the line in slope-intercept form passing through the points (-4,2) and (1,12)
alexira [117]

Answer:

y = 2x + 10

Step-by-step explanation:

Find the slope:

12 - 2 / 1 - (-4)

10 / 5 = 2

Write in point-slope form:

y - 12 = 2(x - 1)

rearrange:

y - 12 = 2x - 2

y = 2x + 10

If 4/5 of the population of a certain town is
kkurt [141]

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600

1,600 of the people are middle class.

I hope this was helpful, keep learning! :D

You will use 220ft of fencing to fence a rectangular plot of land. The length is 20 more than the width. What are the dimensions
PSYCHO15rus [73]
Set up the following equations:

L + W = 110
L - W = 20

110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.

We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

2L = 130

Divide both sides by 2 to get L by itself:

L = 65

The length of the rectangle is 65 feet.

Plug this value into the second equation:

65 - W = 20

Add W to both sides:

65 = 20 + W

Subtract 20 from both sides:

45 = W

The width of the rectangle is 45 feet.
