27 + 27 = 54
Answer:
H(10) Would be the time, in minutes the balloon spent in air . H(10) Means the balloon spent 10 minutes in air
Step-by-step explanation:
The equation of line A:
y-1=0, 5x-3
y=0, 5x-2. Hence its gradient is 0,5
For line B, its you intercept is -8, so y=mx-8.
When x = -4, y=-4m -8 =0 as shown in the graph. This means that m = -2.
Since |-2| > |0, 5|, line B is steeper than line A.
Answer:
y = 3x
