Write the equation of the line that has a slope of m=3 and passes through (4 , 2)
mina [271]

Answer:

y=3x-10

Step-by-step explanation:

For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.

(y-y1)=m(x-x1)

(y-2)=3(x-4)

y-2=3x-12

y=3x-10

To check, you can plug the coordinates into the equation.

y=3x-10

(2)=3(4)-10

2=12-10

2=2

GUYS I NEED HELP ASAP
vovangra [49]

Answer:

A=2400ft

Step-by-step explanation:

A rectangle is a closed planer quadrilateral with four  right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:

Perimeter=w+h+w+h=2w+2h\\\\Where:\\\\w=Width\\h=Height

The ectangular playground is 40 feet wide, so:

w=40ft

Therefore:

Perimeter=2w+2h\\\\200=2(40)+2h\\\\200=80+2h

Solving for h:

2h=200-80\\\\2h=120\\\\h=\frac{120}{2} \\\\h=60ft

The area of a rectangle is equal to the product of two of its contiguous sides, hence:

A=wh\\\\A=(40)(60)=2400ft

I attached you a picture of the rectangle
