Answer:

line r: y=-2x-2

line s: -2x+1

lime t: -2x+3

Step-by-step explanation:

every slope must be -2 since that's stated in the question

to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)

basically, b is the y component when x is 0

Question 19 Only, Please show your work.<br><br> Solve the problem.

ankoles [38]

Answer:

$5\sqrt{2}$

Step-by-step explanation:

Draw a diagonal (line segment from one corner to the opposite corner). You'll form two right triangles with the diagonal being the hypotenuse of both triangles.

Use the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2.

Let h represent the length of the hypotenuse.

$h^2 = 5^2+5^2\\h^2=25 + 25\\h^2 =50\\h=\sqrt{50}\\h=5\sqrt{2}$

The question is just a bit vague. It should say opposite corners. I'm assuming the question does not mean the length of one side!

What does the point (2,24) represent?

almond37 [142]

Answer:

not sure what you mean here but..... 2 represents your x value which will go on the x intercept. And 24 represents your y value. When you have both of these values, you can plot it on a coordinate graph.

Emma uses a 250 meters roll of crepe paper to make steamers how many dekameters of crepe paper does Emma use

Ksivusya [100]

The dekameter (or decameter) first needs to be a translated into how many the meters. deka means 10, so a dekameter it must be 10 meters. So we have to divide 250 by 10, and then we will come up with 25 dekameters.
hope that helps!!
