Hold up. Hee haw. Whoa!
Your first instinct was to multiply it out and get rid of the parentheses.
That's often a good instinct, but this time, it made things harder for you.
This is a good example of a rule you should consider:
Before you do anything to anything, sit back, relax,
LOOK at the problem, THINK about it, and plan your
strategy. Decide what the solution might look like,
and what you're going to do to the given information
in order to move towards the solution.
You might look at this particular equation and ponder:
-- If I multiplied this thing out and got rid of the parentheses, it would
have x³ in it. So there are going to be 3 solutions.
-- If either factor is zero, then the equation is true.
-- One of the factors is 6x. Setting that to zero gives one solution: x=0.
-- The other two solutions come from setting (4x² - 4) = 0 .
-- That's the difference of 2 squares, so it's (2x + 2) (2x - 2) = 0
-- The other 2 solutions come from setting each of those factors to zero.
There you are. You got this far just by thinking, without even picking up
your pencil yet.
Answer:
Step-by-step explanation:
1. Find the slope of the line by plotting the points or by using the equation to find the slope.
2. Plot the line using the slope and find the y-intercept, which is 4.
3. Put your information together to get the equation .
Answer:
Step-by-step explanation:
<u>f(x)=0</u>
Domain are the set of x values
f(x)=0 , we find all the x values where y =0
At x intercepts y is always 0
so we find all the x intercepts.
x intercepts are the points where the graph crosses x axis
In the graph we can see that the graph crosses x axis at
<em>-2.5 , -0.75 and 1</em>
<u><em>-2.5 , -0.75 and 1 are the domain where f(x)=0</em></u>
Answer:
r = 4 inches
Step-by-step explanation:
The radius of a circle is 1/2 of the diameter
r = 1/2d
r = 8/2 = 4
What are the lower, middle, and upper quartiles of this data? 23, 15, 22, 15, 23, 15, 13, 21, 14?

Put them in order.. then the first and last should give you the answer and what ever is in the middle should also give you your 3rd answer
