Step-by-step explanation:
my answer is x-7
hmmm.. I hope its correct#
Answer:
The answer is 4
Step-by-step explanation:
Remove the parentheses
55d + 35 + 15d = 315
Collect the like terms
70d + 35 = 315
Move the constant to the right
70d = 315 - 35
Subtract the numbers
70d = 280
d = 4
Answer:
x^2 + y^2 = 12
Step-by-step explanation:
For a circle with the center at the origin [(h,k) is (0,0)]
use the formula:
x^2 + y^2 = r^2
In this case r is 2sqroot3.
(2sqroot3)^2 is 12.
2•2•sqrt3•sqrt3
= 4•3
= 12
So we get,
x^2 + y^2 = 12
Answer:
(x+1)² + y² = 36
Step-by-step explanation:
<u>Equation of a circle:</u>
(x-h)² + (y-k)² = r²
Center: (h,k)
Radius: r
Given a center of (-1,0) and a radius of 6, we have for our equation:
(x-(-1))² + (y-0)² = 6²
(x+1)² + y² = 36
