The graph is a circle, centered at the origin, with radius=4.
We know that we can write the equation of a circle with radius r and center (a,b) as :
.
Thus, substituting (a, b) with (0, 0) and r with 4, we have:
.
The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:
,
we would still have the same roots.
Thus, the equation of the circle can be written as :
.
Answer: B
Answer:
29
Step-by-step explanation:
To find what isn't a composite number, we need to find which of these is prime. 27 isn't since its 9*3. 28 isn't since its 14*2. 29 is prime
Equation: -34 + y = 7/12x
You are given two points (-1,5), (3, 4)
find the slope: m=(4-5)/[3-(-1)]=-1/4
so you have y=(-1/4)x+b
use either point to find out b: 4=(-1/4)(3)+b =>b=19/4
the equation is y=(-1/4)x+19/4
Answer:
14.86
Step-by-step explanation:
4.5+ 3.8+ 3.2 +2.3=16.7 divided by 5 which I got from how many numbers I added =14.86
