Answer:

y = -4x + 2

Step-by-step explanation:

The equation of a line is written in y = mx + b form, where m is the slope and when finding the slope, it is relatively easy finding the y - intercept. To find the slope of a line perpendicular to a line that you already know the slope of, the slope of a perpendicular line is the negative reciprocal. The negative reciprocal of the slope of y = 1/4 x + 5 is -4, which is the slope of the line we are trying to find. Since we have our slope, we can rewrite our equation as y = -4x + b. Now since we already have a point that it passes through, we have our y-intercept. Our y - intercept is the y coordinate when the x coordinate is 0. Since we have our point (0, 2) we have our y - intercept, which is two. Thus, our answer is y = -4x + 2.

Answer:

y = -4x + 2

Step-by-step explanation:

Well first we have the equation y = 1/4x + 5.

And we have to find the line that is perpendicular to that line that also passes through the point (0,2) so first we have to graph it. Look at the image below.

So we have to find a line that is perpendicular meaning it crosses y = 1/4x + 5 and makes 4 90° angles.

So to start off we know that 2 is the y intercept.

so our equation looks like this y = ?x + 2

We can keep trying x values till we get it.

But we do know that the x value has to be negative.

So the equation is y = -4x +2. Look at the other image below.

A gym charges a monthly fee and an additional cost for each class. Consider the graph that represents the relationship between t
bija089 [108]
For this problem you need to understand that a linear graph is a straight line (Remember Rise/Run). 
A continous function is <span>a </span>continuous function<span> is a </span>function <span>for which sufficiently small changes in the input result in arbitrarily small changes in the output, so we can already cross off that as an answer.
The Y-Intercept is the cost (in dollars), so this would be to monthly fee. 
Now, onto the rate of change. T</span>he rate of change is <span>represented by the slope of a line. So the more classes you take the more it will increase. Therefore the cost for  one class is the rate of change. 
Lastly, the cost for one class is $10. It's not, since $10 is the intial fee to belong to a gym, so this is false. 

Recap:
True
-The relationship is linear
-The y-intercept represents the monthly fee.
-The rate of change represents the cost for one class.
False
-The relationship represents a continuous function. 
-The cost for one class is $10.

I have the first part but I don't know how to do the second part<br><br> h e l p
Debora [2.8K]

\bf \begin{array}{cll} \stackrel{ordinal}{position}&\stackrel{term}{value}\\ \cline{1-2} 1&12\\ 2&12+d\\ 3&12+d+d\\ 4&12+d+d+d\\ &12+3d \end{array}\qquad \implies ~\hfill \begin{array}{llll} \stackrel{\textit{4th term}}{12+3d}~~=~~\stackrel{\textit{4th value}}{3}\\\\ 3d=-9\implies d = \cfrac{-9}{3}\\\\ \stackrel{\textit{common difference}}{d = -3} \end{array}

well, we know the common difference is -3, to go from the 4th term to the 8th term, we need to add "d" 4 times or namely 3+4(-3), likewise to go from the 13th term to the 19th term we have to add "d" 6 times, or namely -24 + 6(-3).

\bf \stackrel{\textit{8th term}}{3+4(-3)}\implies 3-12\implies -9 \\\\\\ \stackrel{\textit{19th term}}{-24 + 6(-3)}\implies -24-18\implies -42

Samantha, Nyla, and Jerry own shares of stock in the Triumph Hotels company. The shares of stock that they own have a combined v
Serjik [45]

Answer:

The value of the shares Samantha owns is $3,010

Step-by-step explanation:

Step 1

We add all the shares together and find out the cost of each share per dollar

Samantha owns 70 shares, Nyla owns 50 shares, and Jerry owns 40 shares.

Total amount of shares = (70 + 50 + 40) shares

= 160 shares

Step 2

The cost of share per dollar =

Values of shares/ Total number of shares

= $6,880/160 shares

= $43

1 share = $43

Step 3

The value of the shares Samantha owns is calculated as:

Number of shares Samantha owns × cost of share per dollar

Samantha owns 70 shares

Hence:

= 70 × $43

= $3010

The value of the shares Samantha owns is $3,010
