Which of the following is the correct algebraic representation for a translation 8 units right and 4 units down?
A. (x + 8, y - 4)
B. (x - 4, y + 8)
C. (x – 8, y + 4)
D. (8x, 4y)

Answers

A. (X + 8, y - 4) hope this helps pls make me brainlyest
The correct answer is A. (x + 8, y - 4)

This is the correct answer because when going right on the x axis, means that you are adding or that it is positive. When going left on the x axis, means you are subtracting, or it is negative.

On the y axis, when going up, you are adding or it is positive. So when you are going down, means you are subtracting or it is negative.

I hope that this helps.

Match each expression in column A with an equivalent expression from column B.



Column A

12r + t − 4r + 6t
(12r + 2t) − (4r + 10t)
12(r + t) − 6(r + t) + 4(r + t) − 2(r + t)


Column B

8(r − t)
8(r + t)
8r + 7t


12r + t − 4r + 6t

Answers

Answer:

see answers below to match them

Step-by-step explanation:

12r + t - 4r + 6t

=12r - 4r + t + 6t

=8r + 7t

(12r+2t) - (4r+10t)

=12r + 2t - 4r - 10t

=8r - 8t

=8(r-t)

12(r+t)-6(r+t)+4(r+t)-2(r+t)

=(12-6+4-2)(r+t)

=8(r+t)

An isosceles triangle has an angle that measures 126°. Which other angles could be in that isosceles triangle? Choose all that apply.

27°
69°
127°
17°

Answers

Answer:

27

Step-by-step explanation:

Since triangles have only 180 degrees in a triangle we can rule out the option that 126 degrees is another angle. So subtract 126 from 180 and you get 54. Then you divide 54 by 2 and get 27.

A storage box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches.

What is the height of the box?

Answers

The height of the box is 3.5in or 3 1/2in
Ok, so first we need the equation. So we know that v=b*w*h. We know that the base is 4 inches and the width is 4 inches as well. So we get the equation v=4*4*h. The volume is also given so the equation changes to 56=4*4*h. So first we multiply the numbers we have to get 56=16*h. Then we divide 16 on both sides. 56/16 is 3.5. We end up with 3.5=h. So the answer is 3.5 inches. You can also put this back in to make sure it is right. To 56=4*4*3.5 is true. So therefore, the answer is 3.5 inches.

Answer:

[tex]b=14.0524019299[/tex]

Step-by-step explanation:

Use the Pythagorean theorem to solve: [tex]a^2+b^2=c^2[/tex]

[tex](6.3)^2+b^2=(15.4)^2[/tex]                <-- plug in a and c values into equation

[tex]39.69+b^2=237.16[/tex]                <-- take out parentheses

[tex]b^2=197.47[/tex]                              <-- subtract 39.69 from both sides

[tex]b=14.0524019299[/tex]                  <-- take the square root of 197.47

for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)

for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)

for C take every x value and subtract 2. (-1,3) should become (-3,3)

for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)
