Answer:

<h2>dimes = $2.41</h2><h2>nickels = $0.24</h2><h2></h2>

Step-by-step explanation:

given:

A piggy bank contains $2.65 in nickels and dimes.

If the number of nickels is 7 less than three times the number of dimes,

find:

how many of each kind of coin are there?

solution;

total = $2.65 = d + n

let d = dimes

    n = nickels

nickels = 3d - 7

plugin values into the formula:

2.65 = d + 3d - 7

2.65 + 7 = 4d

d =<u> 9.65 </u>

        4

d = $2.41

nickels = 3d - 7

            = 3(2.41) - 7

         n = $0.24

These tables represent an exponential function.Find the average rate of change for the interval from x=8 to x=9
GuDViN [60]

Answer:

Option D. 13122 is the answer.

Step-by-step explanation:

As we can see from the table having interval and average rate of change, figures under average rate of change are forming a geometric sequence.

Sequence is 2, 6, 18 , 54, 162, 486.

and we have to find the average rate of change from x = 8 to x = 9, means we have to find 9th term of the given sequence.

Now we know that explicit formula of the sequence can be written as T_{n}=ar^{n-1}

where Tn is the nth term of the sequence.

a = first term

r = common ratio

n = number of the term

Now from this explicit formula we can find the 9th term of the sequence.

From the given table

a = 2, r = 3, n = 9

T_{9}=2.3^{9-1}=2.3^{8}

T9 = 13122

Therefore Option D. 13122 will be the answer.

What is the equation of the line that passes through point (4, 12) and has a y-intercept of —2?
zmey [24]

Answer:

<h2>y = 3.5x - 2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<h3>y = mx + b</h3>

m - slope

b - y-intercept

We have y-intercept b = -2. Substitute:

<h3>y = mx - 2</h3>

We have the point (4, 12) → x = 4, y = 12. Put them in the equation:

12 = 4m - 2         <em>add 2 to both sides</em>

14 = 4m       <em>divide both sides by 4</em>

14/4 = m → m = 3.5
