Numbers that are 10 units from 0 have an absolute value of 10.

Let
x
represent the numbers. This implies that:

|x| = 10

Now let us solve this equation for x.

x = 10 \: or \: - x = 10
\Rightarrow \: x=10 \: or \: x=-10

Therefore there are two numbers that are 10 units away from zero

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

2

Explanation:

There are two directions from 0 on a number line, to the left and to the right.

Numbers to the left of 0 on a number line are negative numbers; numbers to the right of 0 on a number line are positive numbers.

The number 10 units to the left of 0 on a number line is -10, and the number 10 units to the right of 0 on a number line is 10; there are two answers.

What is the equation of a line that has a slope of 2, and contains the point (4,6)?
Tems11 [23]

Answer:

y= 2x -2

Step-by-step explanation:

You would use point- slope formula. y-y = m(x-x). With your numbers it would end up looking like this ---->  y-6 = 2(x-4), then do the distributive property which then gives you ----> y-6 = 2x - 8, then subtract 6 on both sides and you get --->  y = 2x - 2. Hope this helped!!!!

Find the volume of each question in the picture:
Kisachek [45]

Answer:

21.V=1746.1

22.V=1922.7

23.V=54.4

Step-by-step explanation:

V=h*w*l                V=pir^2*h

V=12*8*14 .           V=pi*4^2*8

V=1344 .               V=402.1

V1+V2=1344+402.1=1746.1

V=pi*r^2*h             V=2/3*pi*r^3

V=pi*6^2*13           V=2/3*pi*6^3

V=pi*36*13             V=2/3*pi*216

V=1470.3                V=452.4

V1+V2=1470.3+452.4=1922.7

V=1/3pi*r^2*h           V=1/3pi*r^2*h

V=1/3pi*2^2*6          V=1/3pi*2^2*7

V=8pi                       V=28/3pi

V=25.1 .                    V=29.3

V1+V2=25.1+29.3=54.4

Triangle ABC is similar to Triangle DEF. What is the measure of angle DEF? Refer to image, please show work :)
Ne4ueva [31]
Remember, all the interior angles of a triangle equals 180.
So in triangle ABC, it already gives us two out of the three angles. 

First, we add 52 and 36 and that gives us 88.

Now we subtract 88 from 180.

180 - 88 = 92

So that means that ∠ABC is 92°

Now we have to look at triangle DEF. 
The equation says that triangle DEF is similar to triangle ABC.

Looking at the picture, triangle DEF is smaller and is flipped upside down.

So that means that ∠ABC ≈ ∠DEF

In similar triangles, the measurements of angles does NOT change. Just the side length.

So since ∠ABC = 92° that means that ∠DEF = 92°
