<h3><u>x > -4 is the solution to this inequality.</u></h3>
30 > -6(2x + 3)
Distributive property.
30 > -12x - 18
Add 18 to both sides.
48 > -12x
Divide both sides by -12.
(Because we're dividing by a negative, the inequality sign flips.)
<h3><u>4- < x</u></h3>
S = 2 * (pi) * r * h.....for r
divide both sides by 2 * pi * h
s / (2(pi)h = r
Jamie because it’s showing you the same information but one in a table and on in a graph
You don't have enough math yet to be able to derive the formulas,
so you just have to memorize them:
Area of a circle = (pi) x (radius of the circle)²
Area of a square = (the length of one side of it)²
You may think you can't memorize them, but that'sexactly
what homework is for.
Take ten circles of different sizes and find the area of each one.
Then take ten squares of different sizes and find the area of each one.
You'll remember the formulas for the rest of your life. I guarantee it.
In fact, I'd be very surprised if you're in high school math now and you haven't
already done this for homework.
Let me rephrase that: I'd be very surprised if you're in high school math now
and this hasn't already <em>been assigned</em> as homework.
