Answer:

$n=-20$

Step-by-step explanation:

1) Subtract 2 from both sides.

$\frac{n}{2} =-8-2$

2) Simplify −8−2 to −10.

$\frac{n}{2} =-10$

3) Multiply both sides by 2.

$n=-10*2$

4) Simplify 10 * 2 to 20.

$n=-20$

Therefor, the answer is n = - 20.

Step-by-step explanation:

This question is an example of scientific notation.

To solve this you must

Get it to standard form. If the exponent is negative, you move the decimal to the left. If the exponent is positive, you move the decimal to the right. Do it to the top and bottom.
Now that you have it is standard form, simplify.

The graph of a function f(x) is shown below: plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3

JulijaS [17]

we have the points

$A(-1,-3)\\B(0,1)\\C(1,2.2)\\D(2,3)$

Using a graphing tool

see the attached figure

the domain is the interval---------> $[-1,2]$

$-1 \leq x\leq 2$

the range is the interval--------> $[-3,3]$

$-3 \leq y\leq 3$

therefore

the answer is the option D

integers from $-1 \leq x\leq 2$

A bulletin board measuring 28 dm long was divided among three subject areas in the ratio 2:2:3. How much space was alothed for e

Sphinxa [80]

Answer: Space was alloted for each subject is 8 dm, 8 dm, 12 dm.

Explanation:

Since we have given the length of bulletin board =28 dm

Let the share of three subject areas be 2x,2x,3x

According to question,

$2x+2x+3x=28\\7x=28\\x=\frac{28}{7}\\x=4dm$

so x=4 dm

Now,

Space was alloted for each subject is given as below:

First subject = $2x=2\times 4=8 dm$

Second subject = $2x=2\times 4=8 dm$

Third subject = $3x=3\times 4=12 dm$

Find the unit rate. 48 cupcakes in 6 boxes=cupcakes per box

natka813 [3]

Answer: 8 cupcakes per box

Step-by-step explanation: "Per box" means in 1 box, so we can rewrite the given statement using fractions as

48 cupcakes/6 boxes = __ cupcakes/1 box.

To find out what goes in the blank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 48/6 that has a 1 in the denominator.

If we divide the numerator and denominator of 48/6 by 6,

we get the equivalent fraction 8/1 or 8 cupcakes/1 box.

So now we have 8 cupcakes/1 box = __cupcakes/1 box.

So an 8 must go in the blank which means that the unit rate

for 48 cupcakes in 6 boxes is 8 cupcakes per box.
