Vilka [71]

Answer:

x = -3

Step-by-step explanation:

4x - 5 + 2(x - 3) = 12x + 7

4x - 5 + 2x - 6 = 12x + 7

6x - 11 = 12x +7

6x - 12x = 7 + 11

-6x = 18

What is the area of the fire pit? (Use 3.14 for pi.)

laila [671]

Answer:

$Area = 65.94$

Step-by-step explanation:

I will assume that the shaded region is the fire pit

Given

$R = 5$

$r = 2$

Required

Determine the area of the fire pit

First, calculate the area of the big circle.

$A_2 = \pi R^2$

Area of the small is:

$A_1 = \pi r^2$

The area of the pit is:

$Area = A_2 - A_1$

$Area = \pi R^2 - \pi r^2$

$Area = \pi (R^2 - r^2)$

$Area = 3.14 (5^2 - 2^2)$

$Area = 3.14 (25 - 4)$

$Area = 3.14 * 21$

$Area = 65.94$

What is the slope of the line in the graph?

Sedbober [7]

<h3>Answer: 1</h3>

========================================================

Explanation:

Pick any two points you want from the blue line. I'll pick (0,1) and (1,2)

Apply the slope formula to those points

m = (y2-y1)/(x2-x1)

m = (2-1)/(1-0)

m = 1/1

m = 1

The slope is 1.

Notice how if we're at (0,1), then we move up 1 and over to the right 1 to arrive at (1,2).

slope = rise/run = 1/1

rise = 1, run = 1
