Create an equation with a solution closest to 0 using digits 1 to 9
steposvetlana [31]

Complete Questions:

<em>Create an equation with a solution closest to 0 using digits 1 to 9 </em>

<em>_x + _ = _x + _</em>

<em></em>

Answer:

See Explanation

Step-by-step explanation:

Given

_x + _ = _x + _

Required

Fill in the gap using 1 to 9 to give a result close to 0

First, you have to determine what kind of numbers that are close to 0;

In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;

Next, is to fill in the gaps using trial by error method

5x + 2 = 2x + 3

Checking the above expression

<em>Collect Like Terms</em>

<em></em>5x - 2x = 3 - 2<em></em>

3x = 1

Divide equation by 2

x = 0.33 <em>(Approximated)</em>

Another trial is

6x + 8 = 2x + 7

Checking the above expression

<em>Collect Like Terms</em>

<em></em>6x - 2x = 7 - 8<em></em>

4x = -1

Divide equation by 4

x = -0.25 <em>(Approximated)</em>

<em>I'll stop here but note that, there are more expressions that can fill in the gaps</em>

What is the primary difference between exponential and linear functions?
Yanka [14]

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as x^2, or 5x^2+7x, etc.

An exponential function wouldn't be x^2, it would be 2^x! Or 3^x, or (1.738283)^x, etc. Therefore, D is eliminated.

So, the answer is \boxed{A} and we're done!

LenKa [72]

Answer:

27%

Step-by-step explanation:

The ratio means that for every 11 games won, 4 are lost, so the team has won 11<em>x</em> games, lost 4<em>x</em> games, and played 15<em>x</em> games for some positive integer <em>x</em>. The percentage of games lost is

4x / 15x * 100 = 4/15 * 100 = 26.6666 = 27%
