HELP PLEASE: 40 POINTS Match the following items by evaluating the expression for x = -3.

x^ -2

x ^-1

x^0

x^ 1

x^2
AND THE OPTIONS FOR EACH ONE IS -1/3, 1, 9,1/9,-3

Answers

Answer 1

Answer:

Answer: The required match is

$\left(x^(-2),(1)/(9)\right);~\left(x^(-1),-(1)/(3)\right);~(x^0,1);~(x^1,-3),~(x^2,9).$

Step-by-step explanation: We are given to match the following items with the given options by evaluating the expression for x = -3.

$x^(-2),~~x^(-1),~~x^0,~~x^1,~~x^2.$

We will be using the following property of exponents :

$a^(-b)=(1)/(a^b).$

we have

$x^(-2)=(1)/(x^2)=(1)/((-3)^2)=(1)/(9),\n\n\nx^(-1)=(1)/(x)=(1)/((-3))=-(1)/(3),\n\n\nx^0=1,\n\n\nx^1=x=-3,\n\n\nx^2=(-3)^2=9.$

Thus, the required match is

$\left(x^(-2),(1)/(9)\right);~\left(x^(-1),-(1)/(3)\right);~(x^0,1);~(x^1,-3),~(x^2,9).$

Answer 2

Answer: x^ -2: 1/9

x^ -1: -1/3

x^0: 1

x^1: -3

x^2: 9

Really hope this helped have a good day ;)

For the area of a square or rectangle you multiply the sides. So 2 times 9 is 18. And then for the other it would be 3 times 7, which is 21.

Turner's scores for nine video games are 140, 180, 200, 170, 180, 150, 160, 130, and 121. The mean, median, and mode of his scores are given below.mean = 159
median = 160
mode = 180
Which value gives Turner's game average?

Answers

Answer:

The mean gives Turner’s game average.

Step-by-step explanation:

The median describes the number in the middle from lowest to greatest. The mode describes the number that appears the most. The mean describes the average of the data set.

What number should both sides of the following equation be divided by to solve for x?(6.4) x = 32

A.4
B.6.4
C.6
D.5

Answers

In order to solve the equation (6.4)x = 32 divided by 6.4 on both sides option (B) is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have an equation in one variable:

(6.4)x = 32

Divide by 6.4 on both sides in order to find the value of x:

[(6.4)x]/6.4 = 32/6.4

x = 5

Thus, in order to solve the equation (6.4)x = 32 divided by 6.4 on both sides option (B) is correct.

Answer:
PLEASE HELP THANKS , NEED THIS IN TIME

Answers

Answer:

Step-by-step explanation:

Given that Ian factored

$12x^3y^3 - 24x^2y^3$

$6xy(2x^2y^2 - 4xy^2).$

We find that inside still there are common factors for the two terms.

We can find 2 as common factor and for x, the term x and for y it is y^2

So correct factorisation would be

$12x^2y^3(x-2)$

a. 6xy(2x^2y^2-4xy^2)If you need to multiply 6xy and 2x^2y^2 & 6xy and 4xy^2.You will get 12x^3y^3-24x^2y^3.b. Factorization is not complete because 6xy is not the greatest common factor.c. Complete factor: 12x^2y^3(x-2y).

angel has a total of 97 dimes and nickels. if the total value of the coins is $8.35, how many dimes does he have

Answers

dime=10 cents
nickles=5 cents

835=10d+5n
divide both sides by 5
167=2d+n

total number of coins is 97
97=d+n

we have

2d+n=167
d+n=97
multiply 2nd equation by -1 and add them

2d+n=167
-d-n=97 +
1d+0n=70

d=70

sub back

d+n=97
70+n=97
minus 70 both sides
n=27

70 dimes

He would have $1.35 left
