Simplify

(2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)

Answers

Answer 1

Answer:

Answer:

3x^2 - 9x + 8

Step-by-step explanation:

To simplify:

Distribute the -1 into the second term.
Collect and combine like-terms (terms with the same variables or powers)

The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)

After distributing the -1, the equation becomes:

(2x^2 - 5x + 3) + (x^2 - 4x + 5)

The like-terms are:

2x^2 and x^2
-5x and -4x
3 and 5

Combine the like-terms:

2x^2 + x^2 = 3x^2
-5x - 4x = -9x
3 + 5 = 8

Substitute the simplified like-terms into the expression, in descending order:

3x^2 - 9x + 8

How do I Simplify 2i<6u

Answers

remember you can do anything to an eqyation as long as you do it to both sides (with inequalities, flip sign when multiply or divide by negative)

2i<6u
we see that 2 is a common facotr
divide both sides by 2
2/2i<6/2u
1i<3u
i<3u

just do 2x373v=u And that is how you do it

PLZ HELP ME IM VERY CONFUSED! BRAINLIEST TO THE FISRT PERSON WITH WORK!Consider the following relation: {(1,12),(3,8),(3,11),(6,9),(7,11)}. Which ordered pair could be removed so that the relation is a function?

Answers

Answer:

(3,11) or (7,11)

Step-by-step explanation:

A function cannot have the same second number repeated ( forgot the term for the second number) so removing either (3,11) or (7,11) would leave it being a function

Answer:

im just gonna answer so that other dude can get the brainliest

Byron placed bricks in a row to make a border that was 16.9 feet long. Each brick is 1.3 feet long. How many bricks are in the border? A. 13 B. 12 C. 1.3 D. 1.2

Answers

the answer is A. 13, because 16.9/1.3= 13

If each brick is exactly 1.3 feet, diving 16.9 by 1.3 will produce the exact amount of bricks used.

16.9 ÷1.3 = 13

There are 13 bricks in the border (the answer is A.)
