Which property applies only to addition and multiplication?

2 answers:

C. Because if you have 2+6 and 3×4. Inverse property can inverse 2+6 into 6+2. With 3×4, you can change it into 4×3 and the solution/answer won't change. But if you have division or subtraction, then it won't work. Example:
5-4=1 but 4-5 doesn't equal 1. 14÷7=2, but 7÷14 doesn't equal 2. So that is why C. Inverse Property is the answer

Explain why f(x) = x^2+4x+3/x^2-x-2 is not continuous at x = -1.

liberstina [14]

Answer:

The value of x = -1 makes the denominator of the function equal to zero. That is why this value is not included in the domain of f(x)

Step-by-step explanation:

We have the following expression

$f(x) = \frac{x^2+4x+3}{x^2-x-2}$

Since the division between zero is not defined then the function f(x) can not include the values of x that make the denominator of the function zero.

Now we search that values of x make 0 the denominator factoring the polynomial $x^2-x-2$

We need two numbers that when adding them get as a result -1 and when multiplying those numbers, obtain -2 as a result.

These numbers are -2 and 1

Then the factors are:

$(x-2) (x + 1)$

We do the same with the numerator

$x^2+4x+3$

We need two numbers that when adding them get as a result 4 and when multiplying those numbers, obtain 3 as a result.

These numbers are 3 and 1

Then the factors are:

$(x+3)(x + 1)$

Therefore

$f(x) = \frac{(x+3)(x+1)}{(x-2)(x+1)}$

Note that $\frac{(x+1)}{(x+1)}=1$ only if $x \neq -1$

So since $x = -1$ is not included in the domain the function has a discontinuity in $x = -1$

Directions: Follow the instructions for the following inequalities. 1. 4<7 Multiply both sides by 7 , then by 6, then by 3, t

worty [1.4K]

In the given question, we have to perform this experiment and test if the inequality is true or not.

Adding the same value to both sides of the inequality will not change the inequality sign

<h3>Inequality</h3>

data;

4 < 7
11 > - 2
-4 < - 2
-8 < 8

In the first case, we would do follow the process

$6 * 7 * 4 < 7 * 7 * 6\\168 < 294$

In the second case;

$11 > - 2\\\\5 + 11 > -2 + 5\\3 + 16 > 3 + 3\\4+ 19 > 6 + 4\\23 > 10$

In all the scenarios, the operations did not affect the inequality sign because we are doing it equally to all side and at the end of the day nullifies each other.

Please help!!!! 2 questions 50 points!!!!

Zielflug [23.3K]

Answer:

See below ~

Step-by-step explanation:

Question 1

The missing angles

Both the unknown angles have the same value as the other two angles in the triangles are the same
∠(missing) = 180 - (72 x 2)
∠(missing) = 180 - 144
∠(missing) = 36°

⇒ The sides are equal

⇒ Angles are not 90°

⇒ It is a rhombus

Question 2

The diagonals of the shape bisect other (Statement 1)
NY = NW (given)
XN = NZ (given)
∠XNY = ∠WXZ (vertically opposite angles)
ΔXNY ≅ ΔWXZ (SAS)
They form two congruent triangles (Statement 2)
From these two statements, it is evident the figure is a parallelogram

(111²) how to solve it

ivolga24 [154]

Answer:

12,321

Step-by-step explanation:

111 to the second power (basically 111 x 111) is 12,321. Multiply 111 by 111 since the exponent is 2. I hope this helps!
