Determine the equation of the linear function that has a slope of -4 and passes through the point (2,-4). Write the equation in slope-intercept form and draw/graph the equation

Answers

Answer 1

Answer:

Answer:

Part 1) $y=-4x+4$

Part 2) The graph in the attached figure

Step-by-step explanation:

Part 1)

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-4\npoint\ (2,-4)$

substitute in the linear equation

$-4=-4(2)+b$

solve for b

$-4=-8+b\nb=8-4\nb=4$

substitute

$y=-4x+4$

Part 2) Draw the equation

we know that

To graph a line we need two points

we have the y-intercept (0,4) and (2,-4)

Plot the points, connect them and join to draw the line

see the attached figure

20 POINTS!A circle is cut out of a piece of plywood that is 10 in. square. The scrap is thrown away
What is the area of the circle.
How many square inches are thrown away?

Answers

The piece of plywood is a square, 10 inches on each side.
Its area is (10 x 10) = 100 square inches.

You can cut a circle out of it with any size you want, as long as
the diameter of the circle is not more than 10 inches. You didn't
tell us what size circle, so I'll assume that you cut out the biggest
possible circle.

Diameter = 10 inches
Radius = 5 inches

Area of any circle is (pi) x (radius)²

Area = (pi) x (5)²

Area = (pi) x (25) = 78.5 square inches .

The rest of the plywood is scrap.

You discard (100 - 78.5) = 21.5 square inches.

(By the way ... you cut out a disk, not a circle.)

Answer:x=10

Step-by-step explanation:

multiply both sides by 2, to get x=10

Answer:

x = 10

Step-by-step explanation:

x/2 = 5

x = 5 / 1/2

x = 5 * 2

x = 10

10/2 = 5
