Answer 1

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. ... We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same

Answer 2

Answer:

A)x^2-x-6

B)2x^2-12x+12

C)x^2-4

Step-by-step explanation:

A) Lets break this problem into portions the first part we trying to distribute is x(x-3)

X times X is X^2 and X times 3 is 3x so x^2-3x

Lets work on the second part

2(x-3)

2 times x =2x and 2 times -3 = -6 so 2x-6

And since you are supposed to add them its 2x-6+x^2-3x

x^2 can't be combined so that is seperate but 2x(+)-3x (negative overpowers positiveis) so we have -x and then -6 cant be joined with anything so

x^2-x-6

B) I'm going to go a little faster but it's essentially the same

2x(x-4)-3(x-4)

Multiply2x*x= 2x^2

2x*-4=-8x

combinde these two (2x^2-8x)

Pt.2

-3*x= -3x

-3*-4(negative and negative cancels out and it becomes positive)=12

join (-3x+12)

and then 2x^2-8x-3x+12

you can only combine -8x-3x so -12x

2x^2-12x+12

C) this is level 3

x(x-2) + 2(x-2)

(x^2-2x) +(2x-4)

only like terms is 2x and-2x so combine and its 0

x^2-4

What is the linear relationship?

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

The rule is given in the question, as follows:

y is 3 less than x

For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.

For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).

Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).

The table for the given rule can be completed as follows:

X Y

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?

Answers

Answer:

Step-by-step explanation:

Answer:

Is Mary a guy? :|

Step-by-step explanation:

I did this by just a good guess , not really the right way

2000*.45=900 ( 900 is the old savings)

2000*.2 =400 ( how much her salary went down by )

2000-400=1600 ( new salary )

1600*.45 = 720 ( 45% of new salary is new savings

900-720=180 ( change in savings is 180 , the amount the question asks for)

Mary's old salary was 2,000

A prediction based on the data is reliable, because the means of the samples are close together.

Step-by-step explanation:

Test approved

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given three data sets.

All the samples have 10 data points.

Number of data points = 10

Mean of sample 1 = 9.1

Mean of sample 2 = 9.4

Mean of sample 3 = 8.9

We can see that the mean of the three samples is so close to each other.

So the data is reliable.

Hence the option is A.

An artist mixes paint to make new colors.

If the artist has 2 cups of red paint available and 3 cups of yellow paint available,
how many batches of orange paint can she make?
Enter your answer in the box.

Answers

Answer:

The artist can make six batches of orange paint and it remains one cup of yellow paint

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of red paint for one batch of orange paint = 1/3 of a cup

Amount of yellow paint for one batch of orange paint= 1/3 of a cup

Amount of red paint available = 2 cups

Amount of yellow paint available = 3 cups

2. How many batches of orange paint can she make?

2 cups of red paint = 6/3 = 6 batches of orange paint

3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint

The artist can make six batches of orange paint and it remains one cup of yellow paint
