104.5 and 105.5

Step-by-step explanation:

Unless there are such things are 1/2 room numbers, there is no answer. But algebraically, x + x + 1 = 2x + 1 = 210

2x + 1 = 210

2x = 209

x = 104.5

The inverse function of the given is y^-1=x/2 -4.

The domain of the original function becomes the range of the inverse function, and the range of the given function becomes the domain of the inverse function. The inverse function is denoted by the notation f-1 in relation to the original function f. Swapping (x, y) with (y, x) with reference to the line y = x yields the graph of the inverse function. Only when f is both a one-one and an onto function does it have an inverse, indicated by the symbol f-1. Keep in mind that f-1 is NOT f's inverse. The domain value of x is given by combining the function f and the reciprocal function f-1.

Here the given function is,

=> y = 2x+8

Now interchange x and y then

=> x=2y+8

Now simplify the expression with respect to y then,

=> x-8=2y

=> y =x/2 -4

=>y^-1=x/2 -4

Hence inverse function is, y^-1=x/2 -4

Answer:

The expression equivalent to\((1/\sqrt y)^(^-^1^/^5^) is y^(^1^/^5^)/ \sqrt y\).

To simplify the expression (1/√y)^(-1/5), we can use the rule for negative exponents, which states that a negative exponent is equivalent to a positive exponent when the base is moved to the opposite side of the fraction.

First, we can simplify (1/√y) by rationalizing the denominator as follows:

1/√y = 1/√y * √y/√y = √y/√(y^2) = √y/y

Therefore, (1/√y)^(-1/5) can be written as:

\([(\sqrt y/y)^(^-^1^)]^(^1^/^5^)\)

Next, we can use the rule for raising a power to another power, which is to multiply the exponents:

\([(\sqrt y/y)^(^-^1^)]^(^1^/^5^) = (\sqrt y/y)^(^-^1^/^5^)\)

Finally, we can use the negative exponent rule again to rewrite (√y/y)^(-1/5) as:

\((y/√y)^(1/5)\) = \((1/\sqrt y)^(^-^1^/^5^) is y^(^1^/^5^)/ \sqrt y\)

Step-by-step explanation:

Any value of x must have a bigger negative number than 5. In this case, formally you say that all x values must be LESS than 5 only.

Answer:

(a) A(w) = w(950-2w) = 950w-2w^2

(b) w = 237.5

(c) A = 112812.5

Step-by-step explanation:

First of all the maximum area is always a square. You can get the answer first to check your work later.

950/4 = 237.5

One side is not needed so add that length to the non-parallel side.

237.5+237.5=475 feet is the length and 237.5 feet is the width(s)

A=475*237.5

A=112812.5 square feet

Doing the algebra...

P=l+2w

950=l+2w

950-2w=l

A=lw

A=(950-2w)w

A=950w-2w^2

Answer:

V ≈ 179.8 cm^3

Step-by-step explanation:

Did you know that you can find the volume of a pyramid using a simple formula? It's true! All you need to do is multiply one-third of the area of the base by the height of the pyramid. Sounds easy, right? Well, not so fast. There are a few things you need to watch out for. First, make sure you know what shape the base is. If it's not a square, you might need a different formula. Second, make sure you use the same units for all the measurements. If you mix up centimeters and meters, you'll end up with a very wrong answer. Third, don't forget to round your answer to the nearest tenth of a unit. Nobody likes a messy decimal.

Let's try an example. Suppose we have a pyramid with a square base that has a side length of 7.2 cm and a height of 10.4 cm. What is its volume? Well, first we need to find the area of the base. Since it's a square, we can just square the side length:

B = (7.2)^2

B = 51.84

Next, we plug in the values of B and h into the formula and simplify:

V = (1/3)Bh

V = (1/3)(51.84)(10.4)

V = 179.8144

Finally, we round our answer to the nearest tenth of a cubic centimeter:

V ≈ 179.8 cm^3

And there you have it! The volume of the pyramid is about 179.8 cm^3. Isn't math fun?

Step-by-step explanation:

Step-by-step explanation:

First get x on its own:

Subtract 3 from each side

y - 3 = 2x

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

Now simply switch labels: x↔y

y = x/2 - 3/2

Answer:

\(y=\frac{x}{2}+\frac{3}{2}\)

Step-by-step explanation:

To find inverse of an equation, replace the variables x with y and y with x:

x = 2y - 3

Now we get it in slope-intercept form:

x = 2y - 3

Add 3 to both sides.

x + 3 = 2y

Divide both sides by 2.

\(\frac{x}{2}+\frac{3}{2}=y\)

Swap left and right sides.

\(y=\frac{x}{2}+\frac{3}{2}\)

And this is the inverse of the equation y = 2x - 3.

Answer:

2) y=-3x+36

Step-by-step explanation:

Hi there!

We're given a graph and we want to find the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We'll need two points, so pick any two from the graph

For example, let's do (0,36) and (12,0)

first let's find the slope

The formula for the slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points

we'll be using (0,36) and (12,0)

let's label the points to avoid any confusion

x1=0

y1=36

x2=12

y2=0

Now substitute into the formula:

m=(y2-y1)/(x2-x1)

m=(0-36)/(12-0)

m=-36/12

m=-3

so the slope is -3

here's the equation so far:

y=-3x+b

we need to find b

The equation of the line will pass through both (0,36) and (12,0) so we can use either one of them to solve for b

let's take (12,0) for example

substitute 12 as x and 0 as y

0=-3(12)+b

multiply

0=-36+b

add 36 to both sides to isolate b

36=b

now substitute 36 as b into the equation

y=-3x+36

There's the equation of the line, so the answer is option 2
