Simple enough:
Solve for V:
V/2 + 6 = 14
Put each term in V/2 + 6 over the common denominator 2: V/2 + 6 = V/2 + 12/2:
V/2 + 12/2 = 14
V/2 + 12/2 = (V + 12)/2:
(V + 12)/2 = 14
Multiply both sides of (V + 12)/2 = 14 by 2:
(2 (V + 12))/2 = 2×14
(2 (V + 12))/2 = 2/2×(V + 12) = V + 12:
V + 12 = 2×14
2×14 = 28:
V + 12 = 28
Subtract 12 from both sides:
V + (12 - 12) = 28 - 12
12 - 12 = 0:
V = 28 - 12
28 - 12 = 16:
Answer: V = 16
Answer:
No
Step-by-step explanation:
Ellie should be using 750(g) of flour instead of 650.
Checking, it all looks ok except for the range in number 7.
3 is a line with a slope so all reals (which you've written negative infinity to infinity, fine) make up both the domain and range.
4 is a parabola in the usual orientation, so a domain of all reals. There's a minimum so a range of y >= -1.
