Mathematics

Simplify both sides of the equation

25d-14d+8d = 95

Simplify

19d = 95

Divide both sides by 19

19d/19 = 95/19

d  = 5


I hope that's help !

<span>25d-14d+8d=95
as all of the terms on the left are 'd's then we consider them to be called like terms. When we have like terms we can add or subtract freely.
so:
25d-14d= 11d 
11d+8d = 19d
therefore we get:
19d = 95
this is the same as
19*d=95
to find do we need to 'work backwards' to move the 19 to be with 95.
So to 'work backwards' we do the opposite of multiply and divide it instead to both sides of the equation.
19/19*d=95/19
d=95/19
d= 5</span>

What is a true statement about negative exponents?
Nadya [2.5K]

Answer:

Raising something to a negative exponent is just taking the reciprocal of the amount.

Step-by-step explanation:

Let's assume that you wanted to know what x^{-2} is.

To find it, you would take the reciprocal of the x amount. So x^{-2} becomes \frac{1}{x^{2}}.

This works because of the nature of exponents. Exponents represent the number of times you are multiplying a value by itself. So a^{3} would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase a^{3} to a^{5}, you would have to multiply a with a^{3} two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease a^{5} to a^{2}, you would have to divide a^{5} by a 3 times.

If the exponent is 0, the value is equal to 1. But you can still decrease the exponent into negative numbers. You just divide 1 by a the desired amount of times: \frac{1}{a^{3}} means that you are dividing 1 by a 3 times.

Hope this helps.

3x+8 •59 solve for x
Marina86 [1]

1) Let's solve for x, writing this equation.

3x +8*59 =0

3x +472=0 <em>Subtract 472 from both sides</em>

3x = -472

x= -472/3 or -157.33

2) So the answer is x= -472/3

Give an example of a function g(x) such that has vertical asymptotes at x = −1 and x = 2.
BigorU [14]

Answer:

\frac{69420}{(x+1)(x-2)}

Step-by-step explanation:

An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.
