Answer:
A graph that has an axis of symmetry at x = 3 would be x^2 -6x + 12
Step-by-step explanation:
In order to find a graph that has an axis of symmetry at 3, use the equation for the axis of symmetry of a quadratic.
x = -b/2a
In this equation, a is the coefficient of x^2 and b is the coefficient of x. So, if we use 3 as x and we choose a random number to be a (1), we can solve for the b.
3 = -b/2(1)
3 = -b/2
6 = -b
b = -6
Now that we have this, we can put those two numbers as coefficients. The constant at the end can be anything.
Answer:
240 students
Step-by-step explanation:
28/35=x/300
cross multiply to get 35x=300*28
divide both sides by 35 to get 240
A slope is the change in position with respect to x and y. Use y2-y1 over x2-x1. The 2s and 1s are supscripts in this equation.
Answer:
The reflection is and classic reflection across the y-axis as the y stay the same and the x does not.
