Hello from MrBillDoesMath!

Answer: domain restriction: x <> 3, x <> -3

Discussion:

To determine the domain restriction focus on the denominator of the expression, It is x^2 - 9. The expression is valid for all x except where x^2 - 9 = 0 as we can't dive a quantity by 0.

x^2 - 9 = 0 =>

x^2 = 9 =>

x + 3, -3

Thank you,

MrB

Find the zeros (x-3)(x+5)=0

maxonik [38]

The product is equal zero if one of the factors is equal zero.Therefore:
$(x-3)(x+5)=0\iff x-3=0\ \vee\ x+5=0\\\\\boxed{x=3\ \vee\ x=-5}$

Ryan played in 3 basketball games. He scored 18 points in the first game and 12 points in the second game. If he scored 42 point

stealth61 [152]

The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12

X=6 is a solution to the inequality x−5≤ 10 True or False?

vekshin1

Answer:

$\boxed{\sf{FALSE}}$

$\boxed{\sf{x\leq 15}}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

$\sf{x-5+5\leq10+5}$

Solve.

Add the numbers from left to right.

$\sf{10+5=15}$

$\Longrightarrow: \boxed{\sf{x\leq 15}}$

Therefore, the solution is x≤15, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.

Which of the following is algebraically equivalent to the sum of 4x^2 -8x +7 And 3x^2-2x-5

VARVARA [1.3K]

All you have to do, is combine like terms. Let's go through it:

$(4x^2-8x+7)+(3x^2-2x-5)$

Arrange it so you can easily combine like terms:

$4x^2+3x^2-8x-2x+7-5 = 7x^2-10x+2$

So, your answer for the sum is 1) 7x² - 10x + 2
