Which is a correct way of graphing the line y = –x – 2?

katen-ka-za [31]

Y = -x - 2.....in y = mx + b form, the m represents the slope and the b represents the y int. (and if u didnt already know, -x is the same as -1x)

so in ur equation, the slope is -1 and the y intercept is -2....or (0,-2)

so u would plot (0,-2) and use the slope of -1 to plot another point. Draw a line through the points.

My mom built a new sandbox that is 3 \text { m}3 m3, start text, space, m, end text long, 2 \text { m}2 m2, start text, space, m

erastovalidia [21]

Answer:

$27

Step-by-step explanation:

The dimensions of the sandbox (that is a rectangular prism) are 3m x 2m x 1m.

We need to first find the volume of the sandbox.

The volume of a rectangular prism is:

V = L * W * H

where L = length

W = Width

H = height

The volume of the sandbox is:

V = 3 * 2 * 1 = $6 m^3$

Sand for the sandbox costs $4.50 per cubic meter.

The cost to completely fill the sandbox is:

4.50 * 6 = $27

(PHOTO) Can you please find m

solmaris [256]

Here, 3x-70 = x [ corresponding angles ]

3x-x = 70
2x = 70
x = 35

So, ABC = 3x-70 = 3(35)-70 = 105-70 = 35 degrees

So, your final answer is 35
