How to solve this please? <br><br> 2x - 5 = 4
Nutka1998 [239]
Hey there, below you will find the work and answer to your question.

2x-5=4

First lets get the 2x by itself so we have to add 5 on both sides.
2x-5=4
   +5 +5
2x=9
Now we need to get the X by itself so divide each side by 2
\frac{2x}{2} =  \frac{9}{2}
Now we are left with the following
X=\frac{9}{2}
We must simplfy the fraction
2 will go into 9 four times with 1 left over. So the mixed fraction answer would be:
x=4 \frac{1}{2}
As a decimal you would just divide 9 and 2
x=4.5

Hope this helped!

What is the quadratic in vertex form that has an a value of 8 and a vertex of (5, 6)?
faltersainse [42]

Answer:

y= 8(x-5)² + 6

Step-by-step explanation:

Parabolas have two equation forms, namely; the standard and vertex form.

In the vertex form, y = a(x - h)² + k, the variables h and k are the coordinates of the parabola's vertex.

In this case; a=8, h =5, and k=6

Therefore;

The vertex equation will be

y= 8(x-5)² + 6
