Step-by-step explanation:
f(x) = -16x² + 22x + 3
Factor:
f(x) = (8x + 1) (-2x + 3)
The x-intercepts are (-1/8, 0) and (3/2, 0).
The leading coefficient is negative, so the parabola points down. Therefore, the vertex is a maximum. The x-coordinate is halfway between the x-intercepts.
x = (-1/8 + 3/2) / 2
x = 11/16
f(11/16) = 169/16
So the vertex is at:
(11/16, 169/16)
Graph the x-intercepts and the vertex, then draw a curve through the 3 points.
1,R 2,R 3,R 4,R 1,B 2,B 3,B 4,B 1,Y 2,Y, 3,Y
I was actually just learning this. ^-^
To find the intersection, look at the numbers. and see what numbers do both groups have in common.
In this case, we have { 2, 4, 6, 9 } and { 3, 5, 8 }
As you can see, they both have nothing in common. Number wise.
So the answer would be Null.

Hi! The correct answer is -5/6
Step-by-step explanation:
<em><u>~Simplify the Expression~</u></em>
Answer:
( original - new)/ original * 100 %
Step-by-step explanation:
Take the new amount
Subtract the original amount
( original - new)
Then divide by the original amount
( original - new)/ original
Multiply by 100% to get the percent loss
( original - new)/ original * 100 %
