23 is the prime number bc it isn't divisable by anything
Answer:
1.2%
Step-by-step explanation:
List all the possible pairs and divide 1 by the sum.
Since there were 86 possible pairs,
1/86 is nearly equal to o.o12
The graph is a quadratic function, and the equation of the function is C(x) = (x + 4)(x - 3)
<h3>How to determine the equation of the graph?</h3>
From the graph the x-intercepts are:
x = -4 and x = 3
Rewrite as:
x + 4 = 0 and x - 3 = 0
Evaluate the product of both equations
(x + 4) * (x - 3) = 0* 0
This gives
(x + 4)(x - 3) = 0
Express as a function
C(x) = (x + 4)(x - 3)
Hence, the equation of the function is C(x) = (x + 4)(x - 3)

Answer:
Step-by-step explanation:
So we have the equation:
Combine like terms:
Add:
Add 16 to both sides:
Divide both sides by 8:
So, our answer is 24.5 :)
