Answer:

The answer is option 1.

Step-by-step explanation:

In order to simplify the expressions, you have to collect like terms :

3a² + 9ab + 5 - 4a² - 4ab + 3

= (3a² - 4a²) + (9ab - 4ab) + (5 + 3)

= -a² + 5ab + 8

Answer:

C. {-5,-4, -3, 1, 2, 5}

Step by step explanation:

We have been given a graph and we are asked to find the domain of the relation represented in graph.

We can see that our graph is a series of unconnected points. Our function represents integer values. So we can see that our graph represents a discrete function.    

Since we know that domain of a discrete function is set of inputs values consisting of only certain values in an interval. .

The set of first value from each of the given points would made domain of our function. Upon looking at our graph we can see that domain of our function is -5,-4, -3, 1, 2 and 5.  

Therefore, option C is the correct choice.

What is the answer of the problem; <br> 3x-4+2(x-5)=9x+8-2x
alexgriva [62]

Answer:

The answer to the given problem 3x-4+2(x-5)=9x+8-2x is x=-11

Step-by-step explanation:

Given problem is 3x-4+2(x-5)=9x+8-2x

To solve the equation:

3x-4+2(x-5)=9x+8-2x

3x-4+2x-10=9x+8-2x  (multiplying the term with factor)

5x-4-10=7x+8  (adding the like terms)

5x-14=7x+8  (adding the like terms)

Now taking the terms to one side

5x-14-7x-8=0

-2x-22=0 (adding the like terms)

-2x=22

-x=\frac{22}{2}

-x=11

x=-11

Therefore x=-11

The answer to the given problem 3x-4+2(x-5)=9x+8-2x is x=-11

Solve C = 2πr (solve for "r")<br> C = 15
Jobisdone [24]
C = 2 pi r

but c = 15

15 = 2 pi r
15 = 2 * (22/7) * r
r = (15*7) / 2 / 22
r = 2.386
