Identify the first step to find the equation below.

Answer:

8.4*10^-3

Step-by-step explanation:

Move the decimal point 3 places in order to get a number in the one's place.

Answer:

irrational

are the numbers like 7.55782902..where the numbers aren't repeated

To find the midpoint, we just have to add the x values and divide by two then add the y values and divide by two

x-value = (7 + 3) / 2 = 5

y-value = (2 + 4) / 2 = 3

The midpoint = (5, 3)

Hey there! I'm happy to help!

When multiplying numbers with exponents, all you do is add the exponent numbers, so 5^12×5^8=5^20.

A is not equal to this.

B is also not equal to this. B is 25^20.

C is  wrong as well. It is 5^5.

This leaves us with D, which does evaluate to 5^20. If you raise a power to a power you multiply the exponent numbers, and 5(4)=20.

The answer is D. (5^5)^4.

Have a wonderful day! :D

5^12 * 5^8

5^12+8

5^20

The only option that is equal to that is D.

(5^5)^4

5^5*4

5^20

Best of Luck!

5y 4 to the power

Answer:

about 6 boxes for each

Step-by-step explanation:

both numbers have a common factor of 6, so 8 plates in each box, and 9 bowls in each box. She would need 12 boxes in total.

Answer:

I hope C

Step-by-step explanation:

if I'm wrong please let me know

Answer: C

Step-by-step explanation:

The domain is all real values of x such that x is less than or equal to zero.

If x is greater than  zero then all the positive numbers  will make the number in the square root negative and that will  become an imaginary number.

If x is zero  then the number in the number will be 0 and find the square root of 0 is possible.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ x - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{6(x + 1) - 5(x + 2)}[/tex]

Distribute 6 through the parentheses

Similarly, distribute 5 through the parentheses

[tex] \longrightarrow{ \sf{6x + 6 - 5x - 10}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{ x + 6 - 10}}[/tex]

The negative and positive integers are always subtracted but posses the sign of bigger integer

[tex] \longrightarrow{ \sf{ x - 4}}[/tex]

Hope I helped!

Best regards! :D

Answer:

14.

Step-by-step explanation:

For these types of questions, we will have to work backwards.

I have attached an image with this answer and I will explain it.

------------------------------------------------------------------------------------

She starts off with ?, and we divide 2, because she sold half of her comic books. Then, she buys 7 and she has 14.

---------------------------------------------------------

So, ? [tex]\div2[/tex]+7=14

We can work backwards,

so we will first subtract [tex]14-7=7[/tex] (Opposite of addition is subtraction)

And then [tex]7\times2=14[/tex] (Opposite of division is multiplication)

Answer: 14

Step-by-step explanation: 14 yes correct :)

Answer:

Step-by-step explanation:

the product of odd numbers is always odd

the product of even numbers is always even  

the product of odd number and even one is always even

the sum of two odd numbers is always even

and the sum of two even numbers is always even

so if x is even number we have:

x²=x•x   - even number

x⁴=x²•x²  - even number

3x²=3•x²  - even number

y = x⁴+3x²   - even number

and if x is odd number we have:

x²=x•x   - odd number

x⁴=x²•x²  - odd number

3x²=3•x²  - odd number

y = x⁴+3x²   - even number

Answer:

Step-by-step explanation:

Slope = -1.8

(-0.5,1.9)

[tex]m =-1.8\\(-0.5 , 1.9) = (x_1 ,y_1)[/tex]

Substitute values into point slope form

[tex]y-y_1=m(x-x_1)\\\\y -1.9=-1.8(x -(-0.5))\\\\y -1.9 =-1.8(x+0.5)[/tex]

Answer:

y − 1.9 = −1.8 (x + 0.5)

230 - 125 = 105

If she saves 15 every week

Then

105 ÷ 15 = 7 weeks

It will take her 7 weeks

The Triangle Angle Sum Theorem states that the sum of all interior angles of a triangle add up to 180 degrees.

Only Amy proved the theorem because she used postulates and theorems to construct a logical argument to show that the interior angles in a triangle add up to 180 degrees.

Answer:

-2

Step-by-step explanation:

60/2=6-2n

10=6-2n

6-2n=10

-2n=10-6

-2n=4

n=4/-2

n=-2

(p, q) are on a ratio table which makes them proportional to each other. This means that each point on the graph can be found by multiplying p and q by this proportion.

(p, q), (2p, 2q), (3p, 3q).... (np, nq)

n = any number.  

Answer:

Number of books Zoe read is Bri - 6. Thats as simplified I could get B - 6

Step-by-step explanation:

Answer:

  (a) 412 +A -B

  (b) 412 +A -B + (A-20) -(B+14)

  (c) 378 +2A -2B

Step-by-step explanation:

Water flowing in adds to the amount in the reservoir. Water flowing out subtracts from the amount in the reservoir.

__

(a) 412 + A - B . . . . at the end of January

__

(b) Flowing in was (A -20), flowing out was (B +14). In February, we start with the amount at the end of January.

  (412 +A -B) +(A-20) -(B +14)

__

(c) Simplifying the above, we have ...

  412 -20 -14 +2A -2B = 378 +2A -2B

The answer is the product of their slope is -1.

First, let's break this down. Perpendicular lines are line with opposite reciprocal slopes. Opposite meaning the inverse sign and reciprocal meaning flipped.

For instance,

If a line had the slope of 5, its inverse would have a slope of -1/5.

Now, if we multiply these numbers together,

5 * -1/5 = -1

The 5's cancel out.

This works for any two perpendicular lines

Answer:

The answer is the product of their slopes is -1.

Answer:

A. the total number of hours used to make tables and chairs each month

Step-by-step explanation:

x = number of tables made each month

y = number of chairs made each month

It takes 4 hours to make a table and 2 hours to make a chair.

4x + 2y

The total number of hours used to make tables and chairs each month = 4x + 2y

The correct answer is A

A. the total number of hours used to make tables and chairs each month

Answer:

If you're asking what the cost would be for all 5 friends to buy the supplies it would be $750 because $150(cost of supplies) multiplied by 5(number of people) equals 750.

Step-by-step explanation:

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3.

Step-by-step explanation:

Let the Zach's age be Z years.

6 times older than Zach = 6Z

Zach added 8 to his age and multiplied this sum by 3 = 3(Z+8)

Now,

[tex]6Z=3(Z+8)[/tex]

[tex]6Z=3Z+24[/tex]

[tex]6Z-3Z=24[/tex]

[tex]3Z=24[/tex]

Divide both sides by 3.

[tex]Z=\dfrac{24}{3}[/tex]

[tex]Z=8[/tex]

Therefore, the required equation is [tex]6Z=3(Z+8)[/tex] and Zach's age is 8 years.

Answer:

[tex]d=5[/tex]

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the formula to find distance d:

[tex]d=\sqrt{(4-1)^2+(-1-3)^2}[/tex]

[tex]d=\sqrt{(3)^2+(-4)^2}[/tex]

[tex]d=\sqrt{9+16}[/tex]

[tex]d=\sqrt{25}[/tex]

[tex]d=5[/tex]
