Answer 1
1. N= 16 because like the base are equal so you have to multiply the 8*2

2.N=16 because like the bases are identical but the 2*8 they multiply
Answer 2

Answer:

n = 10 and n = 16

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]

= [tex]4^{10}[/tex] , thus n = 10

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

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](3^2)^{8}[/tex]

= [tex]3^{2(8)}[/tex]

= [tex]3^{16}[/tex] , thus n = 16

How do you solve a y=mx+b equation if x is unkown?
example -
y = 1.29x+2
How do I solve that? Please make sure to explain :) thanks!

Answers

Answer

Y= 2 x= -0.645

Step-by-step explanation:

you basically plug 0 into x and y

y=1.29(0)+ 2

y=2

0=1.29x+ 2

Answer:

Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)

In y = 1.29x+2, 1.29 is equal to m, so that is your slope.

The 2 is equal to the b so your y-intercept is 2.

Here's a  graph to better understand it :)

Match the lines m and n to the statements they represent:

- A set of points where the coordinates of each point have a sum of 2

- A set of points where the y-coordinates of each point is 10 less than its x-coordinate

Match the labeled points on the graph to statements about their coordinates:

- Two numbers with the sum of 2

- Two numbers where the y-coordinate is 10 less than the x-coordinate

- Two numbers with a sum of 2 and where the y-coordinate is 10 less than the x-coordinate

Answers

Answer:

see explanation!

Step-by-step explanation:

Line N

A set of points where the coordinates of each point have a sum of 2

Line M

A set of points where the y-coordinates of each point is 10 less than its x-coordinate

Any coordinate on N has a sum of 2.

Any coordinate on M has a y that is 10 less than the x.

The matching is shown below.

What are Coordinates?

Coordinates are two integers (Cartesian coordinates) or a letter and a number that point to a specific place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).

First, A set of points where the coordinates of each point have a sum of 2

- Any coordinate on N has a sum of 2.

A set of points where the y-coordinates of each point is 10 less than its x-coordinate

- Any coordinate on M has a y that is 10 less than the x.

Two numbers with the sum of 2

- Pont A, B and C.

Two numbers where the y-coordinate is 10 less than the x-coordinate

- Point E and D.

Answer:

120πcm²

Step-by-step explanation:

Since we are keeping this in terms of pi, you do not necessarily need a calculator. I will be doing my calculations as simple as I can.

First we need to figure out the area of the top circle and bottom circle.

We know that the formula for the area of a circle is:

πr²

So we need both circles, our formula becomes:

2πr²

Let's substite our radius in.

2 × π × 4² = 32πcm²

Now we need to find the area of the sides itself. Our formula here is:

2 × π × r × h

Let's substitute our radius and height in:

2 × π × 4 × 11 = 88πcm²

Let's now add both of these together:

88πcm² + 32πcm² = 120cm²

Remember to add your measurements!

Emily had 30 cookies to bring to school for her birthday. Three students wanted two cookies each. Then, a new student came that day and he wanted three cookies. Then, one of the three kids gave their cookies back. Emily was still passing out cookies. How many cookies did Emily have Pass out After the Student gave their Cookies Back?

Answers

21

30-6=24-3=21+2=23

3x2=6

Não sei se é isso

Ok, let’s see here. Emily had a total of 30 cookies, and right off the bat 3 students wanted 2 cookies. 3 times 2 is 6, so that’s already 6 cookies taken away. 30 minus 6 is 24, so currently she has 24 cookies left. Then, one of those 3 kids gave only ONE cookie back, so we take 24, and add 1. Giving us 25. We are trying to see how many cookies Emily has passed out so far, so we take the original number, which is 30, and subtract that by our current number which is 25. Giving us 5, meaning she has passed a total of 5 cookies so far.
