Answer:

The function has a maximum value of 3 that occurs at x = 1.

Step-by-step explanation:

First, note that the leading coefficient is negative. This means that the parabola will curve downwards. Because of this, the function has a maximum. The maximum value will simply be the vertex.

The formula for the x-coordinate of the vertex is -b/2a.

a=-3, b=6, c=0

Plug in the numbers:

x=-(6)/2(-3)

=-6/-6=1

Now, plug 1 back into the original function:

-3x^2+6x

-3(1)^2+6(1)

=-3(1)+6

=-3+6

<h2><u>COMBINED OPERATIONS</u></h2><h3>Exercise</h3>

First, let's solve the subtraction (in parentheses):

$\mathsf{\dfrac{-8\left(2-6\right)}{2}}$

$\mathsf{\dfrac{-8(-4)}{2}}$

Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:

$\mathsf{\dfrac{-8(-4)}{2}}$

$\mathsf{\dfrac{32}{2}}$

Finally, let's solve the division:

$\mathsf{\dfrac{32}{2} = 16}$

<h3><u>Answer</u>: 16</h3>

A washer and a dryer cost $917 combined. The washer costs $67 more than the dryer. What is the cost of the dryer?

mart [117]

917 - 67 = 850 (subtract the difference)
850 / 2 = 425 (divide the cost of the washer/dryer)
425 + 67 = 492 (add the difference)
The dryer costs $492.
