Step-by-step explanation:
f'(2) = 2y + 10
f'(2) = 2(2) + 10
= 4 + 10
= 14
Answer:
0
Step-by-step explanation:
Simplify 1/2
Equation at the end of step 1 :
1 1
((— • 21) - 1) - (— • 12)
3 2
Step 2 :
1
Simplify —
3
Equation at the end of step 2 :
1
((— • 21) - 1) - 6
3
Step 3 :
Pulling out like terms :
3.1 Pull out 6
After pulling out, we are left with :
6 • ( 1 +( (-1) ))
Final result :
0
Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9
S = 3 * (A+9)
S = 3A + 27
71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7
R = A + 9
R = 7 + 9
R = $16
S = 3 * R
S = 3 * 16
S = $48
