(x - xo)^2 + (y - yo)^2 = r^2
[x - (-3)]^2 + [y - (2)]^2 = (1.5)^2
(x+3)^2 + (y-2)^2 = 2.25
Answer: option C
Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100
He sold 100 rackets for $ 20
1.5km = 1500m
To find the percentage take 15 and divide it by 1500, then times by 100
15/1500 x 100 = 1%
Hello there!
I’m not sure if they want me to add the answers together or just do them separately.
Exponents
(-2)^2=(-2)(-2)=4
(7/6)^2=7/6(7/6)=49/36
I hope this helps!
Best wishes.

Factor out the GCF. Do not forget to include the GCF as part of your final answer. In this case, the three terms have a 3x in common, which leaves: Step 3: Multiply the leading coefficient and the constant, that is multiply the first and last numbers together.
