The answer is 54/385, or 0.14025974025974.
Hope this helps!
First let's find the factors of each number:
19: 1,19
21: 1,3,7,21
23: 1,23
25: 1,5,25
21 has 4 factors, 25 has 3 and 23 and 19 are both prime numbers (with two factors). 21 has the most factors.
To solve the problem you have to isolate or separate x from everything else. That means adding 3 to both sides to start.
Answer:

the value of b is -38/3
Step-by-step explanation:
goes through the point (7,-1)
we need to find out b for the given equation using (7,-1)
Plug in 7 for x and -1 for y



subtract 35/3 from both sides


Replace it in the original equation

The quotient of two expressions is the division of the expressions
The quotient of
is 7
<h3>How to determine the quotient</h3>
The expression is given as:

Rewrite the above expression by applying the law of indices

Simplify the exponent
