Answer:
Ex 1: f(2)-f(1)+f(1÷2)=9÷4
Step-by-step explanation:
f(2)=2²-2×2+2=4-4+2=2
f(1)=1²-2×1+2=1-2+2=1
f(1÷2)=(1÷2)²-2×(1÷2)+2=5÷4
Answer:
Both are 55
Step-by-step explanation:
To solve this problem, set the equations equal to each other, solve for n, then plug in the values
Solve for n:
1. 2n+15=3n-5
2. Add 5 to both sides
3. Now you have 2n+20=3n
4. Subtract 2n from both sides
5. You are left with n=20
Next, plug it in:
1. Replace all n's with 20
2. 2(20)+15=55
3. 3(20)-5=55
There you go! Hope this helps!
