How you get your answer is by multiplying 25*8= 125
Answer:
(- 3, - 4 ) and r = 5
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
(x + 3)² + (y + 4)² = 25 ← is in standard form
(x - (- 3))² + (y - (- 4))² = 5²
with centre = (- 3, - 4) and r = 5
$50-x=n
x=50-n

Answer:
x=-1, y=8
Step-by-step explanation:
The given system is
-x+y =7
6x+y=14
We make y the subject in the first equation to get:
y=x+7
We put y=x+7 into 6x+y=14 to obtain

6x+x=14-7
7x=7
x=1
We now put x=1 into y=x+7

The solution is x=1, y=8
Part B
We now verify
-1+8=7 ....True
6(1)+8=14....True
