Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have
we have
The leading coefficient is negative, that means the parabola open downward
The zeros of the function are
Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
Answer:
II. One and only one solution
Step-by-step explanation:
Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Let assume the equation is given as;
x + 3y = 11 .... 1
x - y = -1 ....2
Using elimination method
Subtract equation 1 from 2
(x-x) + 3y-y = 11-(-1)
0+2y = 11+1
2y = 12
y = 12/2
y = 6
Substitute y = 6 into equation 2:
x-y = -1
x - 6 = -1
x = -1 + 6
x = 5
Hence the solution (x, y) is (5, 6)
<em>Hence we can say the equation has One and only one solution since we have just a value for x and y</em>

The answer is a.
When you are solving problems like this you would use the equation y^2=4ax. The x and Y would be the coordinates. Based on the equation you have given the coordinates would be (6,12) and (6,-12), (24 is split up evenly between the y-axis).
Then we go on to solve the equation by plugging in the numbers 12^2=4a(6)
144=24a
144/24=24a/24
6=a
