PLEASE HELP For what value of the variable will the value of 2x+1 be 20 greater than 8x+5?
wlad13 [49]

It will be a negative.

for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11

-2(2) + 1 = -3

but that's only 8 apart, so it'd be higher.

-4(2) + 1 = -7

-4(8) + 5 = -27

BOOM

Tadaaaa,

You probably thought positive, but sometimes it's negative, you know what I mean?

How many solutions does the equation −5a 5a 9 = 8 have? none one two infinitely many
Brut [27]

The given equation does not have any solution.

For given question,

We have been given an equation −5a + 5a + 9 = 8

We know that the like terms are those terms which have same variable to the same power.

Combine Like terms;

0 + 9 = 8

9 = 8

⇒ which is  False.

This statement is false for any values of x

Therefore, the given equation does not have any solution.

Find the sum of these polynomials. (x^2 - 5x + 3) + (2x^2 - 3x - 7)
LenaWriter [7]

Answer:

3x^2 - 8x - 4

Step-by-step explanation:

This is a short and simple question, but it's good!

We are given the expression \left(x^2-5x+3\right)+\left(2x^2-3x-7\right), and simply being asked to combine like elements to simplify the expression. Take a look at the procedure below -

\left(x^2-5x+3\right)+\left(2x^2-3x-7\right) - Remove ( ),

x^2-5x+3+2x^2-3x-7 - Add like elements,

3x^2-5x-3x+3-7,\\3x^2-8x+3-7,\\ - And further simplify to derive solution

Solution = 3x^2-8x-4

<u><em>Hope that helps!</em></u>
