Answer:

D. 10 3/8

Step-by-step explanation:

First make them into a improper fraction

\frac{29}{8} +\frac{27}{4}

Find the lowest common denominator:

\frac{29}{8} +\frac{27*2}{4*2}

Multiply the denominators:

\frac{29}{8} +\frac{27*2}{8}

Multiply the numerators:

\frac{29}{8} +\frac{54}{8}

Combine the fractions:

\frac{(29+54)}{8}

Combine the numerators:

\frac{83}{8}

=

10\frac{3}{8}

Hence, D. 10 3/8 is the Correct answer.

By how much does the dependent variable change in response to a change of 1 unit of the independent variable?
dalvyx [7]

Answer: C) 5

--------------

x = independent variable, y = dependent variable

Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.

-------------------

An alternative is to use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (25 - 15)/(4 - 2)

m = 10/2 <--- this expression shows up again

m = 5 <---- leading to the same answer as before

So we see that the slope formula is a more drawn out method to finding the answer.

Describe what is being done in each step while solving the equation -2x + 6 +6x = 6 ( 2x -3 )
Serggg [28]

-2x + 6 + 6x = 6 (2x - 3) <em>this is the equation</em>

-2x + 6 + 6x = 12x - 18 <em>distributive property has been applied</em>

4x + 6 = 12x - 18 <em>like terms have been added</em>

6 = 8x -18 <em>4x has been</em><em> </em><em>subtracted from both sides</em>

24 = 8x <em>-18 has been added to both sides</em>

3 = x <em>8 has been divided from both sides</em>

<em></em>

I hope this helps! Let me know if I need to explain more or if I got something wrong. Have a nice day!

What key features are necessary and how they can be used to create the sketch of a polynomial function?
Tomtit [17]

The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.

 

<span>1.    </span>The degree will help you find the end behavior.

<span>2.     </span>The vertex shows you where it changes concavity.

<span>3.     </span>X and y intercepts give you a couple of points of reference.

<span>4.     </span>Axis of symmetry is only applicable to even degree polynomials.

 

I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

11 because -7 subtracted by 4 add kore to the 7 so think of it this way -7 is a bad guy and 4 is a bad guy to because its a subtraction so if both bad guys combine you get 11 because a negative with negative makes a positive so its 11
