Answer:

Its y=_x+35

Step-by-step explanation:

Sorry I cant help with the slope bc i cant see the bottom numbers so just look at the example

(10,2) (20,4)

4-2/20-10=2/10

2/10=1/5

so the answer would be y=1/5x+35

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?

stira [4]

Answer:

3.5 cubic units

Step-by-step explanation:

First, find the volume of one cube

Use the cube volume formula, V = s³, where s is the side length

V = (1/2)³

V = 1/8 cubic units

Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes

28(1/8)

= 3.5

So, the volume of the prism is 3.5 cubic units

Which statement explains why △ABC is congruent to △A′B′C′ ? You can map △ABC onto △A′B′C′ reflecting it across the line y = x an

Vikentia [17]

The <u>correct answer</u> is:

You can map ABC to A'B'C' by translating it 6 units left and reflecting it across the x-axis, which is a series of rigid motions.

Explanation:

In ABC, the coordinates are:
A(1, -3)
B(5, 3)
C(4, -1).

In A'B'C', the coordinates are:
A'(-5, 3)
B'(-1, -3)
C'(-2, 1)

Each point is mapped to its image:
A(1, -3)→A'(-5, 3)
B(5, 3)→B'(-1, -3)
C(4, -1)→C'(-2, 1)

Comparing the x-coordinates in the pre-image and image, we notice that the image has an x-coordinate that is 6 less than that of the pre-image:
1-6 = -5
5-6 = -1
4-6 = -2

This means that the figure must be translated 6 units left; that is the only way to have this change on the pre-image to form the image.

Comparing the y-coordinates of the pre-image with those of the image, we notice that they are negated:
-(-3) = 3
-(3) = -3
-(-1) = 1

This means the pre-image was reflected across the x-axis; this is the only way to negate the y-coordinate and not change the x-coordinate.

These are rigid motions because they do not change the shape or size, they simply move it and change its orientation.

I think of a number, n. ALex think of a number. that is 11 more than twice my number. If the sum of our numbers is 5, find Alex'

aliina [53]

Let your number be X. Alex's number will be your number, plus 2x, plus 11. (x+2x+11) = 5.

From there we will have x+2x, which is 3x. So now we have 3x+11 = 5.

Subtract 11 from both sides, leaving us with 3x = -6.

From there we need to divide both sides by 3. Leaving us with x = -2.

Now that we know your number (-2), we can find Alex's number.

So from the word problem, we know that Alex's number is 11 more than twice your number. (2*-2+11) = 5.

So we have 2 times -2, which is -4. -4 plus 11 is 7.

To check our answer we need to add both of these two numbers together and see if they equal 5.

So 7-2 (or -2+7) will be 5. Confirming Alex's number to be 7.
