Answer/Step-by-step explanation:
1.
; 3
Let's solve for a.
(subtraction property of equality)

(division property of equality)


Therefore, 3 is a solution to 9 = 2a + 3
2.
; 7
(- × - = +)
(Subtraction property of equality)

(division property of equality)

Therefore, 7 is not a solution of 
3.
; 1
Therefore, 1 is a solution of
.
4(c-6)
distribute 4(c-6)
4xc and -6x4
youll get 4c-24
The graphs arey=(1/3)x^2
and y=3
they intersect at x=3
so the limits are x=0 and 3
to rotate it about y=k, minus k from every function

which evaluates to 72/5pi
