A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use
or
to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.
Our graph is telling us that
is greater or equal than -1, and also
is less than 3. So our inequality will be:
Both problems give you a function in the second column and the x-values. To find out the values of a through f, you need to plug in those x-values into the function and simplify!
You need to know three exponent rules to simplify these expressions:
1)
The
negative exponent rule says that when a
base has a negative exponent, flip the base onto the other side of the
fraction to make it into a positive exponent. For example,
.
2)
Raising a fraction to a power is the same as separately raising the numerator and denominator to that power. For example,
.
3) The
zero exponent rule<span> says that any number
raised to zero is 1. For example,
.
</span>
Back to the Problem:
Problem 1
The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter a:
<span>
2) x = 2</span>Plug this into
to find letter b:
<span>
3) x = 4</span>Plug this into
to find letter c:
<span>
Problem 2
</span>The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter d:
<span>
2) x = 2
</span>Plug this into
to find letter e:
<span>
3) x = 4
</span>Plug this into
to find letter f:
<span>

Answers: a = 1b = </span>
<span>
c = </span>
d = 1e =

The answer to number 11 is 136.5
(5•4)-8 the answer is 12 because 5 times 4 is 20. Then 20 minus 8 is 12.
Answer:
A). slope = -1/12 y-intercept = 3/2
Step-by-step explanation:
y = -1/12x + b
2 = -1/12(-6) + b
2 = 1/2 + b
3/2 = b
y = -1/12x + 3/2
