Answer:

A. 5/2

Step-by-step explanation:

Can't be c or d since those are negative and b would have a much steeper slope rise over run is how you find side the two points connect by going up 5 and over 2

PLEASE HELP LOOK AT THE PIC BELOW

asambeis [7]

Answer:

The simplest answer is

$\frac{16}{21}$

The reason how I got that is because to divide fractions, you have to turn them improper. Once you've done that, you then can multiply it by using the reciprocal of the second fraction. Once they are rearranged, multiply all the numerators by each other. do the same with the denominators and form a new fraction.

Between what two consecutive integers is <img src="https://tex.z-dn.net/?f=%5Csqrt182" id="TexFormula1" title="\sqrt182" alt="\s

Elden [556K]

Answer:

C. 13 and 14

Step-by-step explanation:

They notice that the square root of 182 is between 13 an 14, and it gives them the idea that the numbers 13 and 14 are the solution.

Let n be the smaller of the two consecutive integers.

Then the other integer is (n+1).

We are given that

n*(n+1) = 182.

Simplify

n^2 + n - 182 = 0,

Factor left side

(n-13)*(n+14) = 0.

The solutions are n= 13 and n= -14.

You may check that both of them satisfy the problem' condition, giving you two answers

the pair (13,14) and the pair (-14,-13).

Many people prefer to solve this problem in a short way.

They notice that the square root of 182 is between 13 an 14,

and it gives them the idea that the numbers 13 and 14 are the solution.

Then these people get the next idea that if the product of 13 and 14 is equal to 182,

then the product of the opposite numbers is also 182, so

both the pairs (13,14) and (-14,-13) are solutions.

Solved and explained in detailed and short modes.

Inverse of y equals 12 to the x

e-lub [12.9K]

Answer:

$f^{-1}(x) = log_{12}(y)$

Step-by-step explanation:

We have the following function

y = 12^x, and we need to find the inverse function.

To find the inverse function we should solve the equation for "x". To do so, first, we need to:

1. Take the logarithm in both sides of the equation:

lg_12 (y) = log _12 (12^x)

(Please read lg_12 as: "Logarithm with base 12")

From property of logarithm, we know that lg (a^b) = b*log(a)

Then:

lg_12 (y) = x*log _12 (12)

We also know that log _12 (12) = 1

Then:

x = log_12(y).

Then, the inverse of: y= 12^x is:

$f^{-1}(x) = log_{12}(y)$
