Answer:
Center: (-2, 4)
Radius: 4
Step-by-step explanation:
To find the centre and radius, we require to identify g , f and c
By comparing the coefficients of 'like terms' in the given equation with the general form.
2g = 4 → g = 2 , 2f = -8 → f = -4 and c = 4 → center=(−g,−f)=(−2,4)
radius = √22+(−4)2−4= √4+16−4=4
Center: (-2, 4)
Radius: 4

Answer:
-343/27
Step-by-step explanation:
15) It is given that the charge of the waffle cone = $1.85
Charge per scoop of an ice cream = $0.60
Let C be the total cost.
So, total charge of one wafflce cone ice cream = charge of the waffle cone + (0.6 times number of scoops
C = 1.85 + 0.6x
16) To find the cost for 6 scoops of ice cream, put x = 6 in the above expression and simplify.
C = 1.85 + 0.6(6)
= 1.85 + 3.6
= 5.45
Hence, cost of 6 scoops of ice cream = $5.45.
Answer:
y = -2x +3
Step-by-step explanation:
Parallel lines always have the same slope
To insert the point, use the slope intercept formula: y =mx+b
insert y (9)
insert x (-3)
insert the slope -2
9 = (-2)(-3) + b
9 = 6+b
subtract 6 from both sides
3 = b
