Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:

Where the point (h, k) is the center of the ellipse
In this case we have the equation

Note that its shape matches that of a ellipse with center (9, -2)

Therefore the answer is the obtion C
Evaluate A² for A = -3.
(-3)² = (-3) * (-3) = 9
Your answer is 9.
If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:
2A = 2(-3) = -6.
Answer:
a) 1
b) 58
c) 47
Step-by-step explanation:
don't really have a step by step explanation I just took the information from the chart and applied it to the questions
34=2x + 16
18=2x
x=9
Robert used 9 grams of iron filings in his first experiment.
Answer:
x=3
Step-by-step explanation:
first let's try to get just 3x on one side. to do this we can subtract 2 from both side of the equation.
3x+(2-2)=11-2
3x=9
now we have to isolate the variable we can divide both sides by 3:
3x/3=9/3
x=3
and you get the answer that x is 3
