Answer:

5 + 0.99s = d

Step-by-step explanation:

5 dollars is the initial price for the site and each song is 0.99, so if you multiply that by s, the number of songs, you'll get d.

Consider this quadratic equation:
zhenek [66]

Answer:

a=2

b=0

c=12

Step-by-step explanation:

The standard form of a quadratic equation is ax²+bx+c=0

Here's the given equation:

2x²+12=0

You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.

The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2

12 has no variable, so that means it'll be c in the equation.

Hope this helps!

What is the solution to the equation?
Lisa [10]
3q + 5 = -2q + 20

add 2q to both sides.

5q + 5 = 20

subtract 5 to both sides.

5q = 15

divide 5 to both sides.

q = \frac{15}{5}

the answer is: q = 3

Which function , A or B has a greater rate of change ? Be sure to include the values for the rates of change in your answer . Ex
arsen [322]
<h2>Answer:</h2>

A rate of change tells us  how one quantity changes in relation to another quantity. In a mathematical language, we can write this as follows:

Rate \ of \ Change=\frac{Change \ in \ y}{Change \ in \ x}

For linear functions. the rate of change is the slope of the line. Thus:

FOR THE TABLE:

By taking two points we can get the rate of change, so let's take (1,5) \ and \ (2,7):

ROC=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ ROC=\frac{7-5}{2-1} \\ \\ ROC=\frac{2}{1} \\ \\ \boxed{ROC=2}

FOR THE GRAPH:

Let's take (1,1) \ and \ (2,4):

ROC=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ ROC=\frac{4-1}{2-1} \\ \\ ROC=\frac{3}{1} \\ \\ \boxed{ROC=3}

As you can see, 3>2 so <em>the ROC of the function given by the graph is greater than the ROC of the function given by the table.</em>
