Answer:

See graph attached

Step-by-step explanation:

Our life is simple because the equation [tex]y=2x+2[/tex] is already put in slope-intercept form.

This form is called slope-intercept because it states exactly what it's called: The number multiplied by [tex]x[/tex] (the constant of proportionality, in this case, 2) is the slope - and the y-intercept is what is being added to the equation (in this case, also 2, since there is a +2 at the end.)

With this info, we can start graphing.

We know that the y-intercept is 2, meaning one point will be (0,2).

We also know that the slope is 2, meaning every time x increases by 1, y will increase by 2. So the next point is (1, 4), the next is (2, 6), and so on.

Answer:

the reciprocal of the slope of f(x) is the same as the slope of f⁻¹(x)

Step-by-step explanation:

To find the equation of a line given two points, we use the formula:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

The standard equation of a line is given by:

y = mx + c; where m is the slope of the line and c is the intercept on the y axis

For the function f(x), we have to select two points, let us select (-6, 9) and (0, 27)

Hence the equation of the line f(x) is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-9=\frac{27-9}{0-(-6)}(x-(-6))\\ \\y-9=\frac{18}{6} (x+6)\\\\y-9=3(x+6)\\\\y-9=3x+18\\\\y=3x+18+9\\\\y=3x+27\\[/tex]

Comparing y = 3x + 27 with y = mx + c, we can see that the slope (m) = 3 and the y intercept is 27

For the inverse function f⁻¹(x), let us use the points (-3, -10) and (0, 9)

Hence the equation of the line f⁻¹((x) is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-(-10)=\frac{-9-(-10)}{0-(-3)}(x-(-3))\\ \\y+10=\frac{1}{3} (x+3)\\\\y+10=\frac{1}{3}x+1\\\\y=\frac{1}{3}x+1-10\\\\y=\frac{1}{3}x-9\\[/tex]

To find the x intercept put y = 0

0 = (1/3)x - 9

(1/3)x = 9

x = 27

Comparing y = (1/3)x - 9 with y = mx + c, we can see that the slope (m) = 1/3 and the y intercept is -9

Hence, the reciprocal of the slope of f(x) is the same as the slope of f⁻¹(x) (i.e reciprocal of 3 = 1/3)

Answer: A

The reciprocal of the slope of f(x) is the same as the slope of f–1(x).

Answer:

[tex]77\div.77\cdot1[/tex]

Step-by-step explanation:

What we're basically looking for here are ways to get 100 using these numbers.

My immediate first thought was "can we divide the 7's by some 7's to get 100?"

I know that [tex]7 \div .7=10[/tex], so I had the idea to make it [tex]77 \div .77 = 100[/tex]. This means that we can use the number 7 four times in the equation [tex]77 \div .77=100[/tex].

However, we're still missing a 1 that we need to include. This is easy, we can just multiply [tex]77 \div .77[/tex] by 1.

So in conclusion, we get [tex]77 \div .77\cdot1[/tex]

Hope this helped!

Answer:

The weekly profit function P(x,y) = 72x  - 0.01x² -0.005xy + 38y -  0.005xy -0.015y²  - 10000

3.5 oz bars = 3560

5 oz bars = 80

The maximum weekly profit = 119680

Step-by-step explanation:

Given that:

the demand functions are p and q

the variable cost of x = 8x and the variable cost of y = 12y

Since the  fixed cost attributed to the division is exist 10,000/week

∴ the total cost C = 8x + 12y + 10000

R(x,y) = p(x) + q(y)

where ;

xp(x) = 80x -0.01x² -0.005y

yqz(y) = 50 -0.005x -0.015y²

R(x,y) = 80x -0.01x² -0.005xy +  50y -0.005xy -0.015y²

The weekly profit function P(x,y) = R(x,y) - C

P(x,y) = 80x -0.01x² -0.005xy + 50 -0.005xy -0.015y² - ( 8x + 12y + 10000)

P(x,y) = 80x -0.01x² -0.005xy + 50 - 0.005xy -0.015y² - 8x -12y - 10000

P(x,y) = 72x  - 0.01x² -0.005xy + 38y -  0.005xy -0.015y²  - 10000

(b) How many of the 3.5-oz size bars and how many of the 5-oz bath size bars should the division produce per week to maximize its profit?

profit will be  maximized if:

[tex]\dfrac{\partial P}{\partial x} =0 \ and \ \dfrac{\partial P}{\partial y} =0[/tex]

given  that:

[tex]\dfrac{\partial^2 P}{\partial x^2} < 0 \ and \ D >0[/tex]

where;

D = Px Py -Pxy²

Now;

[tex]\dfrac{\partial P}{\partial x} =(-0.02 x -0.01 y +72)[/tex]

[tex]\dfrac{\partial P}{\partial y} =(-0.03 x -0.01 y +38)[/tex]

[tex]\dfrac{\partial P}{\partial x} =0 \to 2x+y = 7200[/tex]

[tex]\dfrac{\partial P}{\partial y} =0 \to x+3y = 3800[/tex]

2x + y   = 7200

2x + 6y = 7600  

5y = 400

y = 400/5

y = 80

From

x + 3y = 3800

x + 3(80) = 3800

x = 3800 - 240

x =  3560

∴ 3.5 oz bars = 3560

5 oz bars = 80

What is the maximum weekly profit?

The maximum weekly profit = 72x  - 0.01x² -0.005xy + 38y -  0.005xy -0.015y²  - 10000

The maximum weekly profit = 72(3560)  - 0.01(3560)² -0.005(3560)(80) + 38(80) -  0.005(3560)(80) -0.015(80)²  - 10000

The maximum weekly profit =  256320 - 126736 - 1424  + 3040 -  1424 -96  - 10000

The maximum weekly profit = 119680

Answer:

Axis of Symmetry: x = -4

Vertex: (-4, 54)

Step-by-step explanation:

We use a graphing calc.

Answer:

the equation of the axis of symmetry is [tex]x=-4[/tex]

Step-by-step explanation:

Recall that the x-value of the vertex of a parabola of the form:

[tex]y=ax^2+bx +c[/tex]

is given by the expression:

[tex]x_{vertex}=-\frac{b}{2\,a}[/tex]

therefore, in our case the x-position of the vertex becomes;[tex]x_{vertex}=-\frac{b}{2\,a}=\frac{32}{-8} =-4[/tex]

and since the equation of the axis of symmetry is [tex]x=x_{vertex}[/tex]

Then, the equation of the axis of symmetry is [tex]x=-4[/tex]

Answer:

The cosine of angle C is 5/13, or approximately 0.38.

Step-by-step explanation:

To solve this problem, we must remember what the cosine of an angle represents.  The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.

From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.

Therefore, the cosine of angle C is:

10/26 = 5/13 (simplified)

Answer:

[tex]\frac{3}{4}[/tex] miles

Step-by-step explanation:

Total length of the trail = [tex]4\frac{1}{2}[/tex] miles = [tex]\frac{9}{2}[/tex] miles

She ran the first [tex]\frac{2}{3}[/tex] of the distance i.e.

The distance for which she ran = [tex]\frac{2}{3} \times \frac{9}{2} = 3\ miles[/tex]

Remaining distance = Total length of trail minus the distance for which she has already run = [tex]\frac{9}{2} - 3 = \frac{3}{2}[/tex] miles

Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for [tex]\frac{1}{2}[/tex] of the remaining distance.

The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] Remaining distance

The distance for which Annie walked = [tex]\frac{1}{2} \times[/tex] [tex]\frac{3}{2}[/tex] = [tex]\frac{3}{4}[/tex] miles

So, the answer is: [tex]\frac{3}{4}[/tex] miles

So the "back" of the arrow is on/above -20.

The arrow points to -12.

You added something to -20 to get to -12.

So the first number is -20. You added ? to get -12. -12 is the last number / the answer to the equation.

So the equation from what you have so far is -20 + ? = -12

You need to isolate the ? so that you know what it is.

So to get rid of the -20 (make it 0), you have to add 20. -20 plus 20 equals 0, which basically means it is gone. You also have to add 20 to -12. 20 plus -12 equals 8.

Now the equation is ? = 8.

So you know that the second number is 8.

The equation makes sense; -20 + 8 = -12.

Step-by-step explanation:

The time for each canoe is 3.5 hours

The total distance traveled by the first canoe is not known. Nor is the distance for the second canoe. We do know that the difference is 5.25 miles.

So let the rate of the slower canoe = x

Let the rate for the second canoe = 2x

The first canoe goes a distance of 2*x * 3.5 = 7x

The second canoe goes a distance of 3.5x

The difference = 7x - 3.5x = 5.25

3.5x = 5.25                                       divide by 3.5

x = 5.25/3.5

x = 1.5 which is the rate of the slower canoe

2x = 3  which is the rate of the faster canoe

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

y = 4/3x - 5

Comparing with the general equation above

Slope/ m = 4/3

Since the lines are parallel their slope are also the same

So we have

Slope of parallel line = 4/3

Equation of the line using point (−6,−5) and slope 4/3 is

We have the final answer as

Answer:

See below.

Step-by-step explanation:

Triangle:

The area for a triangle is given by the formula:

[tex]A=\frac{1}{2}bh[/tex]

Where b is the length of the base and h is the vertical height.

We can see that the base length is (2x+4) and the height is (x+3). So, the expression for the area would be:

[tex]\frac{1}{2}(2x+4)(x+3)[/tex]

Rectangle:

The perimeter of a rectangle is given by the formula:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width.

We can see that the length is 2x-1 and the width is 3x+2. Thus, the perimeter is:

[tex]2(2x-1)+2(3x+2)[/tex]

For the area, the formula is:

[tex]A=lw[/tex]

So, the expression for area would be:

[tex](2x-1)(3x+2)[/tex]

Rectangular Prism:

The volume for a rectangular prism is given by the formula:

[tex]V=lwh[/tex]

The length is (x+2), the width is (x), and the height is (2x+1). Thus:

[tex]x(x+2)(2x+1)[/tex]
