Answer:
B) y + 7 = 5x
Step-by-step explanation:
In math, a linear function is one that has a graph that is a line. It looks like this: There are two things that make up the equation: y = f(x) = a + bx. One independent variable and one dependent variable make up a linear function, which is also called a simple function. The independent variable is x, and the dependent variable is y, which is what you're interested in. Also, there are no exponents in a linear function, which means the exponent is one.
7 is the leases common I’m pretty sure
There are 3 significant figures because there are 3 digits which aren't 0's
Answer:
The zero is x = -3
- Use the Rational Zero Theorem to list all possible rational zeros of the function.
- Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
- Repeat step two using the quotient found with synthetic division.

The value of x is 
Explanation:
The expression is 
Adding 
to both sides of the equation, we get,
Using log definition, if 
then 
, we have,
Using exponent rule, 
,
Simplifying, we have,
Dividing both sides by 9, we have,
Simplifying,
Thus, the value of x is
