Answer:
<em>Center ~ ( -4, 3 ), Radius ~ 2; Option A</em>
Step-by-step explanation:
<em>~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2 provided r ⇒ radius of the circle, centered at ( a, b ) ~</em>
1. If we are given the circle formula ( x + 4 )^2 + ( y - 3 )^2 = 4, it would be that the center points ( a, b ) would be the inverse of 4 and -3, provided the formula is -a and -b: center ( -4, 3 )
2. Now the radius in the formula ( x - a )^2 + ( y - b )^2 = r^2, is noted by r such that in ( x + 4 )^2 + ( y - 3 )^2 = 4, r^2 is 4 ⇒ r = √4 = 2
3. We now know that the center of this circle is ( -4, 3 ) with a radius of 2, and the only graph that represents that function is the first graph ~
<em>Answer: Center ~ ( -4, 3 ), Radius ~ 2</em>

Hi there!
We want to solve for c (find the value of c) in 15=
To do that, isolate 1c (also written as c) on one side.
We can add 18 to both sides to remove it from the right side
15=-18
+18 +18
_______________
33=
You want to know how to solve an equation where the coefficient of a term is a fraction
Remember that we want to find the value of 1c.
Multiplying a fraction by its reciprocal (the 'flipped' version of that fraction) will give 1.
For example, multiplying by (the reciprocal of ) will give:
So therefore, we should multiply both sides by the reciprocal of , which would be
Therefore,
Multiply
=
Simplify the fractions
88=c
Hope this helps!
If you need to find the unit rate of just one pound you can just divide. 8.43 divided by 3. You would get 2.81 so it would cost $2.81 for just one pound. I hope this helps!
Answer:
(3) 5(2x+11)
Step-by-step explanation:
Distribute the 5 into the parentheses and you should get 10x +55.
Answer:
X= 9
Step-by-step explanation:
16x-15 = 30+11x
16x-11x =30+15
5x = 45
x=45/5
x=9
I think that should be it
