X= 2 , y= -3
You have to multiply the second equation by a negative and the you'll get, -3x-y=-3. the y's cancel out and then you combine the x's and the 5 and the 3 and then x=2 and then you pick one of the two equations and sub in the x and solve for y.

Answer:
a) 1/2
b) 1/2
Step-by-step explanation:
a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...
m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2
The average rate of change on the interval [2, 8] is 1/2.

b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.
The formula of cylinder: 兀r^2×altitude
Take 兀 as 3.14
In this case,the equation will be:
兀1.5^2×3.5
=2.25兀×3.5
=7.875(3.14)
=24.7275
≈24.74
Thus the answer is B.24.74 m3.
hope it helps!
