Answer:

Yes for 1st and 4th, No for the 2nd, 3rd and 5th.

Step-by-step explanation:

You need to plug the first number in each set of brackets into x and the second number into y. The first equation asks if y is the greater than -x. The only ones this is true for are the 1st, 3rd, and 4th answers, so the 2nd and 5th are no. Now check the 1st, 3rd and 4th to see if the answer is less than or equal to 2 when plugging in x and y. This is true for the 1st and 4th answers, so move those to yes and the 3rd to no.

Answer: Yes for 1st and 4th, No for the 2nd, 3rd and 5th.

Which of the following shows that ABCD is a parallelogram for x=6 and y =8? (20 points)

Answers

Answer:

AB = CD = 44 and BC = AD = 31 ; so ABCD is a parallelogram

Step-by-step explanation:

A parallelogram should have two pairs of parallel sides meaning the length of side AB should be the same as the length of side CD and the length of side AD should be the same as the length of side BC.

First, lets see if line AB is parallel to line CD.

Let's start by finding out the length of line AB.

Since we know x = 6 we will replace x with 6 in the expression:

7(6) + 2 = 42 + 2 = 44

Now that we know the length of line AB is 44, lets find the length of line CD by replacing x with its value of 6:

9(6) - 10 = 54 - 10 = 44

Now that we know the length of line CD is 44, we can see that line AB is parallel to line CD since they both have the same length of 44.

Now, lets see if line BC is parallel to line AD.

Let's start by finding out the length of line BC.

Since we know y = 8 we will replace y with 8 in the expression:

3(8) + 7 = 24 + 7 = 31

Now that we know the length of line BC is 31, lets find the length of line AD by replacing y with its value of 8:

5(8) - 9 = 40 - 9 = 31

Now that we know the length of line AD is 31, we can see that line BC is parallel to line AD since they both have the same length of 31.

Conclusion

ABCD is a parallelogram because it contains two parallel sides.

Julio says, "If you subtract 12 from my number and multiply the difference by -5, the result is -40." What is Julio's number?

Answers

Answer:

Julio's number is 212

Step-by-step explanation:

(x - 12) ÷ -5 = -40

x - 12 = -40 times -5

x - 12 = 200

x = 200 + 12

x = 212

Check:

(x - 12) ÷ -5 = -40

((212 - 12)) ÷ -5 = -40

200 ÷ -5 = -40

-40 = -40

Which representations have the same rate of change of y with respect to x as the equation x + 2y = 6

Answers

I think that it is D all of the above

The slope of all the given options are equal and it is equal to slope of given equation .

So, All of the above

Given

Equation of a given line is [tex]x+2y=6[/tex]

Lets find out slope m by writing the equation in y=mx+b form

[tex]x+2y=6\\2y=-x+6\\y=\frac{-1}{2}x+6[/tex]

The slope of the line is [tex]\frac{-1}{2}[/tex]

Now we find slope of each option using formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Lets pick two points from the graph to find out slope

Pick (0,3) and (6,0)

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-3}{6-0} =\frac{-1}{2}[/tex]

Now pick two points from option B to find slope

(-10,-3) and (0,-8)

[tex]m=\frac{-8+3}{0+10} =\frac{-1}{2}[/tex]

Now we consider the third option

[tex]y=\frac{-1}{2}x+2\\slope = \frac{-1}{2}[/tex]

Slope of all the options are same and it is equal to the slope of given equation

So, all the above
