Answer:

A =  6  +  B /x −  4 /x

B  =  Ax  +  4  −  6 x

x = b-4/a-6

Step-by-step explanation:

hope this helps :)

The values of A and B that will result in an equation with infinite solutions are 6 and 4

For an equation to have infinite number of solutions, the equations on both sides must be the same,

Given the equation

Ax + 4 = 6x + B

If the equation has infinite number of solution, then

Ax = 6x

A= 6

Similarly

4 = B

B = 4

Hence the values of A and B that will result in an equation with infinite solutions are 6 and 4

Answer:

x = 2 and y = -2

Step-by-step explanation:

a) 5x-4y = 18

b) x+3y = -4

b) x = -3y - 4

a) 5 (-3y - 4) - 4y = 18 (substitution)

a) - 15y - 20 - 4y = 18

a) -19y = 18 + 20

a) y = 38/-19

y = -2

b) x + 3(-2) = -4

b) x - 6 = -4

9514 1404 393

Answer:

Step-by-step explanation:

For price p, the quantity q of units sold is said to be ...

  q = 3000 +10(80-p)/0.10 . . . . for price in dollars

Then the revenue will be ...

  r(p) = p·q = p(3000 +100(80-p)) = 100p(110 -p)

The cost is said to be ...

  c(q) = 250 +4.20q

  c(p) = 250 +4.20(100(110 -p)) = 250 +420(110 -p)

Then the profit function is ...

  P(p) = r(p) -c(p)

  P(p) = 100p(110 -p) -(250 +420(110 -p)) = (110 -p)(100p -420) -250

__

Ignoring the vertical offset of -250, the quadratic has zeros at 110 and 4.2. So, its line of symmetry (and vertex) will be found at ...

  p = (110 +4.2)/2 = 57.1 . . . . dollars per unit

The quantity that should be produced at that price is ...

  q(57.1) = 100(110 -57.1) = 5290 . . . . units produced

The profit at that price is ...

  P(57.1) = (110 -57.1)(100·57.1 -420) -250 = 52.9(5290) -250

  = $279,591 . . . . best profit

Additional comment

After you have seen a few of these, you can write down the revenue function based on the rate of change of units sold.

If p is the price of a unit, then 80-p is the number of dollars of decrease in price for a price of p. Then (80 -p)/0.10 is the number of 10¢ decreases in price. The increase in units sold is 10 times this, or 10(80 -p)/0.10 = 100(80 -p). When that is added to 3000 units sold, the total is ...

  3000 +100(80 -p) = 3000 +8000 -100p

  = 11000 -100p = 100(110 -p) . . . . . quantity sold at price p

Revenue is the product of price times the number of units sold at that price.

Profit is the difference between revenue and cost.

Answer:

1. Use variables to represent length and width.

width = w

length = w + 5

2. Set up an equation for the perimeter of the rectangle.

perimeter = 2L + 2W

2(w + 5) + 2(w) = 46

2w + 10 + 2w = 46

4w + 10 = 46

4w = 36

w = 9

3. Find the length and width of the rectangle.

width = w = 9 inches

length = w + 5 = 14 inches

Answer:

Width is 9 inches

Length is 14 inches

Step-by-step explanation:

width = w

length = w + 5

perimeter = 2L + 2W

2(w + 5) + 2(w) = 46

2w + 10 + 2w = 46

4w + 10 = 46

4w = 36

w = 9

Width = w = 9 inches

Length = w + 5 = 14 inches

Therefore the width is equal to 9 inches and the length is 14 inches.

Answer:

first subtract the 2 cancelling out on the left side, making the -3 a -5, then add y cancelling out the left side, making the right side -5+y, than your equation is 5x=-5+y, dividing the 5 off makes x=-5+y/5. :)

Answer:

A. 2

Step-by-step explanation:

Our y-axis is equivalent to f(x), so we can use it to find the value of x when f(x) = 4. If we look at the graph, we can find that an f(x) value of 4 (or, a y-value of 4) has an x-value of 2.

We could also figure this out by making f(x) equal to 4 in the equation:

[tex]4=2^{x}[/tex]

2 times itself how many times is equal to 4? Well, 2 times 2 is equal to 4, so 2 times itself two times is equal to 4. x is equal to 2:

[tex]4=2^{2}[/tex]

Either way works. If you have any more questions, let me know! :)

Answer:

y = - [tex]\frac{1}{2}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line

m = [tex]\frac{-1-1}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

All real numbers less than or equal to 4.

f(x) ≤ 4

Interval notation:  (-∞, 4]

Step-by-step explanation:

Given the quadratic function, f(x) = -(x + 5)(x + 1), where the vertex occurs at point, (-3, 4):

Since the graph of the parabola opens down, then it means that the vertex  is its maximum point. In reference to the vertical points on the graph (i.e., the range values), then the vertex sets the maximum range value of k = 4. This implies that the maximum possible range value is from negative infinity to positive 4.

Therefore, the range of the function is: all real numbers less than to or equal to 4.

Step-by-step explanation:

The volume [tex]V_s[/tex] of a sphere of radius R is is given by

[tex]V_s = \frac{4\pi}{3}R^3[/tex]

so a hemisphere will only have half the volume of a sphere so we can write its volume [tex]V_h[/tex] as

[tex]V_h = \frac{1}{2}V_s = \frac{2\pi}{3}R^3[/tex]

Since the diameter D is twice the radius R, we can rewrite [tex]V_h[/tex] in terms of D as

[tex]V_h = \frac{2\pi}{3}\left(\frac{1}{2}D\right)^3 = \frac{\pi}{12}D^3[/tex]

[tex]\:\:\:\:\:\:\:=\frac{\pi}{12}(12\:\text{cm})^3 = 452.4\:\text{cm}^3[/tex]

Now represents the amount of water inside the hemisphere, which will be then transferred to a cylinder 8 cm in diameter. The volume of this cylindrical can [tex]V_c[/tex] must equal the volume of the hemisphere:

[tex]V_h = V_c = \pi R^2h = \pi\left(\frac{1}{2}D\right)^2h[/tex]

[tex]\:\:\:\:\:\:\:=\frac{\pi}{4}D^2h[/tex]

where h is the height (or depth) of the can. Solving for h, we get

[tex]h = \dfrac{4V_h}{\pi D^2} = \dfrac{4(452.4\:\text{cm}^3)}{\pi(8\:\text{cm})^2}[/tex]

Step-by-step explanation:

Grams is used for smaller objects, and liters is used for a liquid, centimeters, is used to measure distance, and same with yards,feet,kilometers, meters. the correct answer is pounds.

Ron weighs the books so he uses to pound unit to measure the weight of the books.

The group of units used to quantify different physical quantities is collectively known as the units of measurement. Since ancient times, we have measured these things using many units, including length, mass, volume, current, and temperature. Since then, these units of measurement have changed, and we now use new, more practical and user-friendly systems of measurement.

Centimetres are used to measure distance, same as yards, feet, kilometres, and metres are used to measure larger objects, liquids are measured in litres, and tiny objects are measured in grammes.

Since Ron weighs the books so he uses to pound unit to measure the weight of the books.

Therefore, the correct answer would be pound.

A rectangle is a quadrilateral which has the length of its opposite sides to be equal. Thus, the following are the solutions to the questions:

a) The rectangle used to model the taller building is ABCD.

b) The line segment used to model the height of the smaller building is JM = KL.

c) The height of the taller building is 200 feet.

d) The height of the smaller building is 150 feet.

e) Yes, the scale factor from small to tall building is [tex]\frac{3}{4}[/tex].

Rectangles have equal length of opposite sides , and the sum of its interior angles to be [tex]360^{o}[/tex]. Since the two given skyscrapers were modeled with respect to rectangles ABCD and JKLM, then the answers to the questions are:

a) The rectangle used to model the taller building is ABCD. Since the length of a rectangle is always greater than its width. So that the height; AD = BC.

b) The line segment that can be used to model the height of the smaller building is; JM = KL. This represent the width of the rectangular model for the small building.

c) The height of the taller building is AD = BC = 200 feet. The width of a rectangle is often smaller than its length, which in this case is the height.

d) The height of the smaller building is JM = KL = 150 feet. The length of a rectangle is usually longer than its width.

e) Yes, it would make sense because:

scale factor = [tex]\frac{height of the smaller building}{height of the taller building}[/tex]

                   = [tex]\frac{150 ft}{200ft}[/tex]
