Answer:
Step-by-step explanation:
Given the equation:
1/5 × (x - 2) = 20
First step to solving the equation is
By multiplying both sides by the value of 5.
That will give,
x - 2 = 100
x = 100 + 2
= 102
The input is known as x and the output is known as y in math.
So you’re stating that we’re making the equation equal the output, y, and we’re adding based off of the word “more”. Now that we know we’re adding, we have to find what we are adding together. We are adding x and 11 is that it equals y. Note that x and y could be many different variables and values.
Y= x+11
anything multiplied by one is itself, anything multiplied by zero is zero
A pair of tires is $216, so at that rate 4 tires would be $432. The managers special is $380 so $432-$380=$52 savings for 4. $52\4=$13 savings per tire.
Given:
The quadratic equation is
To find:
The vertex of the given quadratic equation.
Solution:
If a quadratic function is 
, then
We have,
It can be written as
...(i)
Here, 
.
Putting 
in (i), we get
On further simplification, we get
So, the vertex of the given quadratic equation is 
.
Therefore, the correct option is A.
