Step-by-step explanation:

Answer:

y=1/5x-1

Step-by-step explanation:

SI form is Y=mx+b

Example: What is 3 squared?

3 Squared== 3 × 3 = 9

"Squared" is often written as a little 2 like this:



This says "4 Squared equals 16"

(the little 2 means the number appears twice in multiplying, so 4×4=16)

Square Root

A square root goes the other direction:



3 squared is 9, so a square root of 9 is 3

Answer:

21/5000

Step-by-step explanation:

0.0042 takes the form of 21/5000 as a fraction.

Answer:

21/500

Step-by-step explanation:

0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)

42 is an even number so, divide by 2 to simplify.

42/2 = 21 and 1000/2 = 500

21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.

Hope this helps! :)

Answer:

28.75

Step-by-step explanation:

We can do 15% of 25 which is 3.75. Add this on to 25, and get 28.75.

The amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

The raise = 15 % of 25 = 3.75

Total after raise = 25.00 + 3.75 = $28.7

Thus, the amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

After 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
To find the total cost of the songs,
= 12 songs × $0.80/song = $9.60

Then, the total cost of the subscription and the songs over 6 months:
= $9.99 + (6 × $9.60)
= $9.99 + $57.60
= $67.59.

So, after 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

Step-by-step explanation:

Answer:

5.5

Step-by-step explanation:

Add each side of the triangle.

3z+z+1+4z-3 = 8z - 2

8z - 2 is equivalent to the  perimeter.

Since you know the perimeter is 38 units, you can set 8z-2 to 38.

8z-2 = 38

Solve for z. Subtract 2 from each side.

8z = 36

Divide each side by 8.

z = 4.5

Now solve for side WX.

WX = z + 1

WX = 4.5 + 1

WX = 5.5

x= 4/3

Step-by-step explanation:

Answer:

Hope it helps

Step-by-step explanation:

So you want to get x by itself.

x3= [tex]\frac{64}{27}[/tex]

You could simplify

x3=2.37037037037

Then just divide 3 on both sides

x=0.79012345679

Or you can divide a fraction by a whole number and just divide the numerator and the denominator by 3.

x= [tex]\frac{21.3}{9}[/tex] or just 2.36666666667.

Answer:

A. x ≥ -3 and x < 2, or -3 ≤ x < 2

Step-by-step explanation:

Remember solid dot means include, open dot means not include.

x ≥ -3: this means x is greater and equal (includes) -3.

x < 2: this means x is less than 2 and does not include it.

Answer:

A

Step-by-step explanation:

So on the number line you see a closed circle at -3 and an open circle at 2.

Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.

So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].

The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].

To combine it together, it would get [tex]-3 \geq x < 2[/tex].

Since option A is [tex]x \geq -3[/tex] and  [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.
