Here is the graph of y= 7 - x for values of x from 0 to 7 a) On the same grid, draw the graph of
y = x-1
10
9

b) Use the graphs to solve the
simultaneous equations
y = 7 - X and y = x-1
x=
y =
0 1 2 3 4 5 6 7 8 9 10

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
