Answer 2

Answer:

Yes

Step-by-step explanation:

Because -5x and 5x both have the same things in it (a full base number and variable), they are like terms. It doesn't matter that one is a negative and the other is not. It's just matters that everything else is the same.

Over what interval is the graph of y=−2 +|x− 2| increasing?
a. (2, ∞)

b. (−2, ∞)

c. (−∞, −2)

d. (−∞, 2)

Answers

Answer:

(2, ∞)

Step-by-step explanation:

An absolute value graph at (0, 0) is an up facing V shape graph. After a few transformation, according to the equation y = −2 + |x− 2|, we have our vertex at (0, - 2). It remains at up facing V graph.

x - h,

x - 2,

x - (+ 2),

h = 2

Therefore our slope is 2, with out vertex at (0, - 2). If we plot our graph, you can see that on the interval (2, ∞) the graph increases...

Multiply.
(2x + 4)(x - 4)

Answers

Answer:

-2x-16

Step-by-step explanation:

so what you are going to do for this is use the distributive property. 2x will be multiplied by x and -4. then you will take 4 and multiply x and -4. then you combine your alike terms. 2x-8x+4x-16 you should get -2x-16

The equivalent expression after multiplying is 2(x² - 2x - 8).

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(2x + 4) (x - 4)

Remove the parenthesis.

2x² - 8x + 4x - 16

Add like terms.

2x² - 4x - 16

Taking out the common factor.

2 (x² - 2x - 8)

Thus,

The final expression is 2(x² - 2x - 8).

8x + 6y = 28

9x + 3y = 39

Set to equal y.

8x + 6y = 28

6y = -8x + 28

y = -8/6x + 28/6

y = -4/3x + 14/3

9x + 3y = 39

3y = -9x + 39

y = -9/3x + 39/3

y = -3x + 13

Set equal to each other.

-4/3x + 14/3 = -3x + 13

Combine like terms.

5/3x = 25/3

Multiply by 3/5

x = 5

Plug x in.

y = -3(5) + 13

y = -15 + 13

y = -2

What must be true about the average rate of change between any two points on the graph of an increasing function?

Answers

Answer:

If a function is increasing, the average rate of change between any 2 points must be positive.

If we have an increasing function, the average rate of change between any two points must always be positive.

What must be true about the average rate of change?

For an increasing function f(x), we have that if:

b > a

Then:

f(b) > f(a).

Now, we define the average rate of change on an interval (a, b) as:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, because:

b > a

f(b) > f(a)

Then:

b - a > 0

f(b) - f(a) > 0.

So both numerator and denominator are positive, which implies that the quotient must be positive.

Then, if we have an increasing function, the average rate of change between any two points must always be positive.

Step-by-step explanation:

If m∠SKL=31° and m∠JKS=52°, what is the measure of ∠JKL?

Answers

Answer:

the angle is 97 because in a triangle all the angles add up to 180 so if you add 52 + 31 it equals 83 then you subtract 83 from 180 and get 97

The value of JKL is 97°.

It should be noted that the total angles in a triangle are equal to 180°.

Therefore, SKL + JKS + JKL = 180°

31° + 52° + JKL = 180°

JKL = 180° - 31° - 52°

JKL = 180° - 83°

JKL = 97°

The value of JKL is 97°.

Step-by-step explanation:

because the straight line is 180 so if you add 35+55=90 and 90+90=180

Answer:

35°

Step-by-step explanation:

What I did was look at ∠ABC and know that collinear is a straight line, and that a straight line is equal to 180°. Then I saw that ∠ABD was a right angle or 90° and that ∠BCE was equal to 55°, so I added those 2 together and got 145°. then I subtracted that from the 180°. because that is what a straight line equals and I got 35°. So, I would say ∠DBE is equal to 35°.
