Answer:
x = -4, 5/2
Step-by-step explanation:
A quadratic can be solved may ways, including graphing, factoring, and the quadratic formula. You can also check possible answers by making use of the relationships between solutions and the coefficients.
__
A graph is attached. It shows the solutions to be -4 and 5/2.
__
When factored, the equation becomes ...
(2x -5)(x +4) = 0 . . . . . has solutions x=-4, x=5/2 (these make the factors zero)
__
Using the quadratic formula, the solutions of ax^2 +bx +c = 0 are found from ...
x = (-b±√(b²-4ac))/(2a)
x = (-3±√(3²-4(2)(-20))/(2(2)) = (-3±√169)/4 = {-16, +10}/4
x = {-4, 5/2}
__
For ax^2 +bx +c = 0, the solutions must satisfy ...
product of solutions is c/a = -20/2 = -10
Only the first and last choices have this product.
sum of solutions is -b/a = -3/2
Only the first choice (-4, 5/2) has this sum.
Answer:
i belive its 100
Step-by-step explanation:
Answer:
X=-2/5,7
Step-by-step explanation:
5x² – 33x - 14 = 0
5x^2-(35-2)x-14=0
5x^2-35x+2x-14=0
5x(x-7)+2(x-7)=0
(5x+2)(x-7)=0
X=-2/5,7
so the value of X is -2/5,7
Volume because of weight and surface
Rotation and reflection are instances of transformation
See attachment for the new position of 
From the question, we have:


The rule of 90 degrees clockwise rotation is:

Using the above transformation, the new points would be



The next transformation is reflection over the x-axis
The rule of this transformation is:

So, the new points would be:



See attachment for the new points
