We are given the following relation:

y = 4.302 x – 3.293

To solve for the mean value of y when x = 20, what we have to do is to find for the value of y at x = 20 and the value of y at x = 0. Then we get the average of the two values.

when x = 0

y(0) = 4.302 (0) – 3.293

y(0) = - 3.293

 

when x = 20

y(20) = 4.302 (20) – 3.293

y(20) = 82.747

 

The mean value would be:

mean y = [y(20) + y(0)] / [20 + 0]

mean y = [82.747 + (-3.293)] / 20

<span>mean y = 3.9727 = 3.97</span>

22/d = -2 what is d
Natasha_Volkova [10]

Answer:

-11 =d

Step-by-step explanation:

22/d = -2

Multiply each side by d

22/d *d = -2*d

22 = -2d

Divide each side by -2

22/-2 = -2d/2

-11 =d

The graph of relation r is shown. Which of the following graphs represents the relation and it’s inverse
elena55 [62]

Answer:

I attach the missing image from your question.

To easily solve this question, we must realize that the graph of the relation is very similar to that of the expression

y = √(x-a) , where a>0

If we take a look at the image attached, we have plotted the graph of

y = √(x-1) , and its correspondent inverse function.

This means that the answer is the first option

Examine the system of equations.
MakcuM [25]

Answer:

\boxed{\boxed{\sf x=-3}}

Step-by-step explanation:

\sf y = -3x - 2

\sf y=7

We'll substitute y into the equation:

\sf 7 = -3x - 2

Switch sides:

\sf -3x-2=7

Add 2 to both sides

\sf -3x-2+2=7+2

\sf -3x=9

Divide both sides by -3:

\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}

\sf x=-3

Therefore, the value of x/solution is -3
