Answer:
x=3
Step-by-step explanation:
In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?
<em>In order to find out, you need to get X by itself. </em>
The first step is to subtract 115 from both sides.
7x+115=136
-115 | -115
7x=21
Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.
7x=21
/7 | /7
x=3
This is because you have 7 X's and you need to have only 1 of the X's.
Let me know if this was helpful or if you need any more help. Have a nice day. :)
Answer:
Step-by-step explanation:
Hello, the vertex is (1,2), right?
You remember that when the parabola equation is in standard form like below
The vertex is for , and we apply with this example where a = 1, b = -2, c=3
So this is the first graph.
Thank you
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
