What is the inverse of y= 10^x +8?

shepuryov [24]

Answer:

$x = \log_{10}(y - 8)$ , where $y > 8$ .

Step-by-step explanation:

The question is asking for an expression for $x$ in terms of $y$ .

The first step is to move as many constants away from the side with $x$ as possible. In this question, that could be done by subtracting $8$ from both sides of the equation.

$y - 8 = 10^{x} + 8 - 8$ .

$y - 8 = 10^{x}$ .

Notice how $x$ is in the position of an exponent. Logarithms could help move $x$ out of that position.

For any base $b > 0$ :

$\log_{b} b^{x} = x\, \log_{b}\, b = x$ .

In this question, $10$ would be the base. That is: $b = 10$ .

Take the logarithm (with $10$ as the base) of both sides of the equation $y - 8 = 10^{x}$ :

Left-hand side: $\log_{10} (y - 8)$ .
Right-hand side: $\log_{10} \left(10^{x}\right) = x\, \log_{10}\left(10\right) = x$ .

Equate both sides to find an expression for $x$ :

$x = \log_{10}(y - 8)$ .

NEED HELP ASAP!!!

Reika [66]

To effectively and correctly answer this and help we'll need a photo diagram for the question. We need to see a graph of some sort to even know where to start this off. It'd probably be solvable without a diagram if you don't have one, but I don't think that many people have the skill to do so (at least I don't). I know how terrible I feel when no one answers my questions, so I thought I'd let you know why others might not be answering this for you. I'm pretty sure you can update the question and attach a photo (an actual photo or a screenshot) to it, via the paperclip icon. Have a great day! :)

Find the value of x such that the data set has the given mean. 98,122,104,115,107,x,102 x=(Type an integer or a decimal.)

dedylja [7]

Answer:

x = 66

Step-by-step explanation:

For a set of N numbers:

{x₁, x₂, ..., xₙ}

The mean can be calculated as:

$M = \frac{x_1 + x_2 + ...+ x_n}{N}$

In this case we have the data set:

{98, 122, 104, 115, 107, x}

And I assume that we want to have the mean = 102.

So we have a set of 6 numbers, the mean of this set will be:

$M = \frac{98 +122+104+115+107+x}{6} = 102$

We need to solve this equation for x.

If we multiply both sides by 6, we get:

(98 + 122 + 104 + 115 + 107 + x) = 102*6 = 612

546 + x = 612

x = 612 - 546 = 66

x = 66

2. Which equation is equivalent to x+8 = 21?

lakkis [162]

Answer:

The most obvious one i can think of would be

x = 13

Step-by-step explanation:

x + 8 = 21

x + 8-8 = 21-8

x = 13

The bakers at Healthy Bakery can make 270 bagels in 10 hours. How many bagels can they bake in 15 hours? What was the rate per h

Tcecarenko [31]

Answer:

405 bagels 27 an hour

Step-by-step explanation:

this is because when you divide 270 by 10 you get 27 which is how much per hour then multiply the # of bagels and the # of hours you get is 405. In other words you first want to know how many bagels it took to get to 270 bagels in 10 hours.Hope it helped.
