Answer:
C ( 1,-2)
Step-by-step explanation:
We can plot the points and see what point is not in the shaded section
It would be C because the 40° is acute and the last degree is obtuse
Answer:
Yes it is, You can rearrange the expression to find that y is uniquely determined in terms of x, therefore a function.
Step-by-step explanation:
Solving this inequality is similar to solving a regular equation. The only thing you need to worry about with inequalities is that when you are dividing or multiplying by a negative number, you must flip the inequality sign. You won't have to worry about that here!
You are told x + 3/4 ≥ -1/3. Isolate the x by subtracting 3/4 from both sides. To subtract fractions, find a common denominator on both fractions, subtract the numerators, put the difference over the common denominator, and simplify if needed. The common denominator between
and
is 12.
1) To make the denominator of
, 12, multiply it by 3/3 (aka 1):
2) To make the denominator of
, 12, multiply it by 4/4:
3) Subtract the fractions to find the inequality for x:
You answer is x ≥ -13/12, or if you want to make -13/12 a mixed number, x ≥
.
Answer:
-1/2
Step-by-step explanation:
Divide the first expression by the second expression.
