Greetings!
Let's rewrite the equation:
b = 4c - s².
Plug in your values:
b = 4(25) - (9)²
Now simplify:
4 times 25 equals 100
9 squared equals 81
So, b = 100 - 81
Calculate:
100 minus 81 equals 19
b is 19.
I hope this helps!

Answer: y = 2/5 --> y = 0.4
Step-by-step explanation:
The equation 5y = 2 represents a horizontal line at y = 2/5.
This means that the y-coordinate holds the value of 2/5 = 0.4 for any x-coordinate.
Answer:
To express the ratio of a number x with four plus two, you can set up the equation:
= 4x + 2 = 0
= 4x = -2
= x = -2/4 = -1/2
Step-by-step explanation:
I hope this helps!
