How do you work out this math problem?? 2+2x-5=5(x+3)

2 answers:

5 0

1) Simplify the problem

This involves combining variables

2-5=-3

Now that is -3+2x= 5x+15

2) Find the hidden variable.

Now that the problem is in order you can find the hidden variable of x.

So think what number in place of x makes this equation true?

There are may ways you can solve for x, including the substitution method.

The first step i'd take is distributing the right side, by multiplying everything in the parentheses by 5 , so ; 2+2x-5=5x+15

then you could gather similar or like terms on one side, by moving all the x terms to the right, and all the regular terms to the left. to do this, you do the same thing on both sides of the equation

2 +2x -5 = 5x +15
-2x -15 = -2x -15

2-5-15 = 3x

What is the horizontal asympote of this graph?

Anna35 [415]

Using it's concept, it is found that the graph has no horizontal asymptote.

<h3>What are the horizontal asymptotes of a function f(x)?</h3>

The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

In this problem, we have that:

The function is undefined for x < 0, hence $\lim_{x \rightarrow -\infty} f(x)$ is undefined.

For x > 0, the funciton goes to infinity, hence $\lim_{x \rightarrow \infty} f(x) = \infty$ .

Thus, the graph has no horizontal asymptote.

Help pleaseeee???!!!

Answer:

h=8

Step-by-step explanation: $\frac{-7}{8} h= -7\\\\(\frac{8}{-7} )(\frac{-7}{8} h)= -7 (\frac{8}{-7} )\\\\\frac{-56}{-56}h = \frac{56}{7}\\\\ h=\frac{56}{7}\\\\h=8$

the goal is to isolate the variable, get it all by itself. to do that in this problem, we have to move the -7/8 away from the h. we do this by multiplying by the reciprocal (the opposite of the fraction). The reciprocal of -7/8 is 8/-7. So multiply both sides by this and you will get h=8
