Equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
In this case:
<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4
</span>Equation:
(x - 2)^2 + (y - 7)^2 = 4^2
(x - 2)^2 + (y - 7)^2 = 16
Hope it helps.
I'm just gonna assume that the question is what's the total number of cars he has/ the other part of his collection
His whole collection has 45 cars in it. I got that by multiplying 60% by 27
the other 40% of his collection is made up of 18 cars
Answer: C
Step-by-step explanation:
A function only exists if each x-value has only one possible y-value.
C is the only function because each x-value has only one y-value.
The other answer choices have x-values that have multiple y-values. In answer choice A, it has (2,9) and (2,8). In answer choice B, the set has (1, 0) and (1,2). And in answer D, it has (1,3) and (1,2)
Answer:
Step-by-sThe standard form is Ax + By = C
with A being both positive and non-fraction
so we are given 3x - 9 = 7y
we add the 9 to both sides
3x = 7y + 9
and subtract the 7y from both sides
3x - 7y = 9
