Answer:

It is the same distance from 0 as the original number

a rational number is any number that can be written as a fraction.

lets say she picked 1/4...the opposite would be -1/4...both are equidistant from 0.

Answer:

Step-by-step explanation:

Opposite: Shen's number changes sign, e. g., -2 to +2.

If you meant "reciprocal," then you must ensure that the denominator of the 'new' number is never zero. 3/5 => 5/3 is ok. But x/6 = 6/x is OK ONLY for x not equal to zero.

1 solution. it can't be 2, and if you solve it, there is a solution, x stays in the equation, so there's 1 solution

If 2x+20 and 3x+20 makes a straight angke find value of x

erma4kov [3.2K]

Answer:

x = 28

Step-by-step explanation:

The sum of the angles in a straight angle = 180°

Sum the angles and equate to 180

2x + 20 + 3x + 20 = 180

5x + 40 = 180 ( subtract 40 from both sides )

5x = 140 ( divide both sides by 5 )

x = 28

1. What is the growth/ decay rate for this exponential function?

Firdavs [7]

Answer:

1. The growth rate is 2

2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5

Step-by-step explanation:

The growth and decay factor in an exponential function is the number that is being multiplied to the power of x

It is a growth rate when that number is greater than 1
It is a decay rate when the number is less than 1
If it's 1 then it's not growing or decaying
If it's 0 you will have an answer of 0

Please help<br> Me<br> Quick

Mrac [35]

Answer:

Step-by-step explanation:

First figure out the equation:

We know this is a linear equation because it appears to have a constant slope

Its y-intercept is where it passes in the y-axis, so it's -8

Furthermore, you should also figure out the slope. Notice that the y value increments by 3 every 1 x-value. Rise/Run is 3/1 = 3. Thus, the slope is 3

So your equation is g(x) = 3x - 8

Now we find our inverse function, which is just swapping the x-y values.

Thus, inverse of g(x) ==> y = 3x - 8 ==> x = 3y - 8 ==> x+8 = 3y ==> $\frac{x+8}{3}$

Plug in 7 for x and you get 5
