Answer:
12 and 13
Step-by-step explanation:
(a)
To evaluate f(g(2)), evaluate g(2) then use the value obtained to evaluate f(x)
g(2) = 2(2) - 1 = 4 - 1 = 3, then
f(3) = 3² + 3 = 9 + 3 = 12
--------------------------------------------
(b)
To evaluate g(f(2)), evaluate f(2) the use the value obtained to evaluate g(x)
f(2) = 2² + 3 = 4 + 3 = 7, then
g(7) = 2(7) - 1 = 14 - 1 = 13
BD=7x-10
Answer: x=bd/7 + 10/7
BC=4x-29
Answer: x=Bc/4 + 29/4
CD=5x - 9
Answer: x= cd/5 + 9/5
Y = 5 - 2x
3 = 5 - 2(1) True
1=5-2(2) True
3=5-2(0) False
0,3 is not a solution
Answer:
-11 =d
Step-by-step explanation:
22/d = -2
Multiply each side by d
22/d *d = -2*d
22 = -2d
Divide each side by -2
22/-2 = -2d/2
-11 =d
