Answer:
C
Step-by-step explanation:
When she first noticed the problem
X equals 60 degrees (80-20=60)
First move the 14x over to get 7y=-14x-9 then divide by 7 and you get y= -2x-9/7. the slope is the value next to the x in y=mx+b form so the slope is -2
So 1 USD is 2.89 RON
That means...
177 ÷ 2.89 = 61.24USD
Answer:
centre = (0, 0 ), radius = 5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 25 ← is in this form
with centre = (0, 0 ) and r =
= 5
