1) For any one input there is only one output,

So because there are 2 x's with 4 and they both have different outputs ( y values are different) it cannot be a function.

The answer is D.

2) There are two x's using -3 and each Y value is different, one is 2 and the other is 0, so it is not a function.

The answer is D.

Answer:

y = 3 | x + 2 | - 5

Step-by-step explanation:

The absolute value function is:

y = | x |

Step 1. Function is vertically stretched by a factor of 3:

y = 3 * | x |

Step 2. Shifted two units left:

y = 3 | x + 2 |

Step 3. Shifted 5 units down:

y = 3 | x + 2 | - 5

(7x²+8+5)+(3x²-2x-2) add polynomials

eimsori [14]

Answer:

10x²+11-2x

Step-by-step explanation:

I hope you mean 7x²+8+5, not 7x²+8x+5.

We need to combine like terms. Anything with squared should be added together, et cetera.

(7x²+8+5)+(3x²-2x-2)

You can take out the parenthesis, because they don't matter in addition.

7x²+8+5+3x²-2x-2

Add the terms, step by step. Each bold pair needs to be added together.

7x²+8+5+3x²-2x-2

10x²+8+5-2x-2

10x²+11-2x

Now there's no more we can add together.

Can someone please help me with this question?

liq [111]

To get the solution we are looking for we need to point out what we know.
1. We assume that 55 is 100% because its the output value of the task.
2. We assume that the x is the value we are looking for.
3. If 100% = 55 so we can write it down as 100%=55
4. We know that x% = 44 of the output value so we can write it as x%=44.
5. Now we have two simple equations: 1) 100%=55 2) x%=44 where left sides of both of them have the same units and both right sides have the same units so we can do something like that 100%/x%=55/44.
6. Now we just have to solve the simple equation and we will get the answer.
7. Solution for 44 is what percent of 55 100%/x%=55/44 (100/x)*x=(55/44)*x we multiply both sides of the equation by x 100= 1.25*x we divide both sides of the equation by (1.25) to get x 100/1.25=x 80=x now we have: 44 is 80% of 55!

Quick answer = 44 is 80% of 55
Hope this helps! ;D
