Step-by-step explanation:822.73
You required to find the value of d.
Always remember the concept that if you transpose "+" sign to the other side, it becomes "-" sign, and vice versa. Make sure that you arrange the like terms and constants. Solving the equation,
6d + 1 = 15 - d
6d + d = 15 - 1
7d = 14
d = 14/7 = 2
When transposing a multiplication, you divide it to the other side.
Verifying the solution,
6(2) + 1 = 15 - 2
12 + 1 = 13
13 = 13
Answer:b
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k) = (5, 7) and r = 2 ⇒ r² = 4, hence
(x - 5)² + (y - 7)² = 4 → A
