we have
This is a vertical parabola open upward
The axis of symmetry is equal to the x-coordinate of the vertex
The vertex is the point (h,k)
the equation of the axis of symmetry is
In this problem
so the x-coordinate of the vertex is
<u>Convert the quadratic equation in vertex form</u>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
remember that
so
substitute in the equation
therefore
<u>the answer is</u>
A two-dimensional figure, because it doesn't mention it's rate of change or the rise over run it has on graphs or table of values.
Answer:
y = x² - 6x +5
Step-by-step explanation:
(x -1)(x-5) = y
x² - 5x - x + 5 = y
x² - 6x +5 = y
Answer:
Solution given
:total n[U]=590
customers using coupon n[C]=177
the percentage of all customers who often use coupons=177/590×100%=30%.
If n[U]=5000
no of customer using coupon be x
we have
30% of 5000=x
x=30/100×5000
x=1500
<h3>
<u>So1500 people</u><u> </u>would you expect to use a coupon if all 5,000 people in the community visited the store.</h3>
11x + 12(11x + 1) = 12
11x + 132x + 12 = 12
143x = 0
x = 0
y = 11x + 1
y = 11(0) + 1
y = 1 <==
