Answer:
(1.5,2.5)
Step-by-step explanation:
f(x) = 2x^2 - 6x + 7
Take the first derivative and set it equal to 0 (the slope is 0 at the vertex)
f'(x) = 4x -6
0 = 4x - 6
4x = 6
x = 3/2 or 1.5
If x = (3/2), then y = 2(3/2)^2 - 6(3/2) + 7
y = 2(9/4) - 18/2 + 7
y = (9/2) - 2
y = 2.5
See attached graph.
Answer:
increase
Step-by-step explanation:
percentage increase = new value (5) - original value (4) /original value (4) x 100
5-4 = 1
1/4 = .25
.25 x 100 - 25%
percentage decrease = original value -new l value / original value x 100
Answer:
no solution
Step-by-step explanation:
x2-x1/y2-y1
8-5/-4+4= 3/0
3/0 = N/0 solution
You can do:
-two trapezoids
-six triangles
-two parallelograms
You can't put it into one rectangle, that will definitely not work.
As you can see from the attachment, triangles work, trapezoid as well, and two parallelograms. The one rectangle would not work.
I hope this helps!
