Answer:
Step-by-step explanation:
(5 + (-1))/2 = 4/2 = 2
(8 + (-4))/2= 4/2 = 2
(2, 2) is the Midpoint
Fraction: -5/12 Decimal= -0.416
We are given : Zeros x=7 and x=4 and leading coefficent 1.
In order to find the quadratic function in standard form, we need to find the factors of quadratic function first and the multiply by given leading coefficent.
For the given zeros x=7 and x=4, we get the factors (x-7) and (x-4).
So, we need to multiply (x-7) and (x-4) by foil method.
We get
(x-7)(x-4) = x*x + x* -4 -7*x -7*-4
x^2 -4x -7x +28.
Combining like terms, we get
-4x-7x = -11x
x^2 -4x -7x +28 = x^2 -11x +28.
Now, we need to multiply x^2 -11x +28 quadratic by leading coefficent 1.
We get
1(x^2 -11x +28) = x^2 -11x +28.
Therefore, the required quadratic function in standard form is x^2 -11x +28.
X²+3x-4=0. a=1; b=3; c=-4. D=b²-4ac=9-4*1*(-4)=25. D=25.
Paul : company B
30,000 + 10(2400) = 30,000 + 24,000 = 54,000
Sharla : company C
36,000 + 10(2000) = 36,000 + 20,000 = 56,000
Sharla made more....she made (56,000 - 54,000) = 2,000 more
