2/3 / 8/7 flip the second fraction and multiply straight across
2/3 x 7/8 2 x 7 = 14
3 x 8 = 24 so you have 14/24 if you need to simplify, since both numerator and denominator are even so divide by 2. Which gives you 7/12
Hope this helps you :)
Answer:
b=2
c=-24.01
Step-by-step explanation:
If I understood your question right you need to find the constants b and c in the polynomial:

such that:

In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.
I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:

When you solve the system you get the answers above.
