(3x + 8)
=(5x - 40)
Remove the brackets and replace 3x with -40 and -40 with 3x.
40 + 8
=5x - 3x (Remember that when you replace, the signs change from negative to positive and vise versa)
Solve for x. x= -24
Replace x with its value.
3(-24)+ 8= -64
5(-24) - 40= -160

He can buy 5 boxes of light bulbs..
20 x 5= 100
He only has 120 to spend - the shipping = 110
He can't get another box of lightbulbs. Therefor he can only buy 5!
(3x³ + 2x² - 5x) - (8x³ - 2x²<span>) =
</span>3x³ + 2x² - 5x - 8x³ + 2x² =
-5x³ + 4x² - 5x
The vertex (5,39)
5 is the value of x. 39 is the value of y. y is the cost function of the minimum value in dollars.
(5,39) vertex means that <span>Buying five of each type of plant costs $39, which is the lowest possible cost.</span>
