Answer and Step-by-step explanation:

Alot of these can be solved with the table up above the problems.

According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.

According to the table, when we have a negative exponent, the number gets turned into a fraction of [tex]\frac{1}{x^x}[/tex]

Since our value is 9^-2, do as followed :

[tex]\frac{1}{9^2}[/tex]

Solve what is 9^2 :

[tex][\frac{1}{81} ][/tex]

[tex]\frac{1}{x^{-5} }[/tex]

This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.

[tex]x^5[/tex]

[tex]5a^3b^{-2}[/tex]

Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.

[tex]\frac{5a^3}{b^{2}}[/tex]

[tex]-3^4 = -3*-3*-3*-3=-81[/tex]

Since -3 is in parenthesis, we can rid the negative along with the parenthesis :

[tex](-3)^4=3^4=3*3*3=81[/tex]

Follow the negative exponent rule :

[tex](-3)^{-4}=\frac{1}{(-3)^4} =\frac{1}{3^4} =\frac{1}{3*3*3*3}= \frac{1}{81}[/tex]

Follow the negative exponent rule yet again :

[tex]-3^{-4}=-\frac{1}{3^4} =-\frac{1}{3*3*3*3} =-\frac{1}{81}[/tex]

Answer:

2/5

Step-by-step explanation:

you want to start with the point on the left and then count 2 up to the line that the other point is on than you count over 5 to the point on the right

then you put rise over run which makes it 2/5

Answer:

2/5

Step-by-step explanation:

Step-by-step explanation:

Formula of area

AREA = LENGTH (multiply) BREATH

Answer:

The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.

In this case, 4 is the base, and 7 is the height.

So we have: Area = 1/2(4)(7)

Simplifying: Area = 2(7), Area = 14.

The area of the triangle is 14 meters squared.

Answer:

-2x - 6 = 2 - 4x - (x - 1)

-2x - 6 = 2 - 4x - x + 1

-2x - 6 = 3 - 5x

3x = 9

That is the furthest it can be simplified without solving it.

Answer is x=3 if needed.

Please brainliest if this helped.

Answer:

x = 6

Step-by-step explanation:

(x + 2) + (2x + 3) = 23

Combine like terms

3x +5 = 23

Subtract 5 from each side

3x+5-5 = 23-5

3x = 18

Divide each side by 3

3x/3 = 18/3

x = 6

Answer:

x = 6

Step-by-step explanation:

1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23

2. Add constants. x + 5 + 2x = 23

3. Combine like terms. 3x + 5 = 23

4. Subtract "5" from the constants on both sides of the equation. 3x = 18

5. Divide both sides by 3. 3x/3 = 18/3

6. Simplify. x = 6

Answer:

x = 7

angle (7x + 8) = 57 degrees

Step-by-step explanation:

all triangles interior angles add up to 180 degrees.

(7x+8) + 90 + 33 = 180

7x+8 = 57

7x = 49

x = 7

(7x + 8) = 57

Answer:

57 degrees

Step-by-step explanation:

7x+8+33=90

7x=90-8-33

=90-41

7x=49

x=7

Answer:

(D)

Step-by-step explanation:

I dont know tis for sure and so i hope im right :)

Step-by-step explanation:

5x+6+6x-25=180

We move all terms to the left:

5x+6+6x-25-(180)=0

We add all the numbers together, and all the variables

11x-199=0

We move all terms containing x to the left, all other terms to the right

11x=199

x=199/11

x=18+1/11

Answer:

the answer is below :)

Step-by-step explanation:

BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  ($120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x to find where the gigabytes are the same.

100 + 10x = 120 + 5x

Subtract 100 from both sides:  10x = 20 + 5x

Subtract 5x from both sides:  5x = 20.

Divide both sides by 5:  x = 4.  4 gigabytes is the answer.

a brainliest would be appreciated :)

The total amount you will pay for phone service is 4 gigabytes.

An equation is an expression that shows the relationship between two or more numbers and variables.

BigBytes will be 100 +10x = y

Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  

We have $120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x;

100 + 10x = 120 + 5x

Now Subtract 100 from both sides:  

10x = 20 + 5x

Then Subtract 5x from both sides:

5x = 20.

Now Divide both sides by 5:  

x = 4.  

Hence, the total amount you will pay for phone service is 4 gigabytes.

x=10

Step-by-step explanation:

THis is isosceles triangle

180-90-45=45

used pyagorous therum thingy

10over2= square root of 200

so c2=asquare X b squared in this case x=y

so 200/2 = 100

x=100square

y=100 square

simplify = 10
