Answer:
Hi Friend!
The Correct Answer is 1/2
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-1/5, 7/10) = 10
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
Answer: the slope is 2!
Step-by-step explanation:
That slope appears to be 4/6 or 2/3.
The perpendicular slope will have the opposite sign and be the reciprocal.
The perpedicular slope is –3/2.
Answer: 
Step-by-step explanation:
It is important to remember that an Exponential function has the following form:
Where “b” is 
and 
, "a" is a coefficient, "x" is the Independent variable and f(x) is the Dependent variable.
In this case, you have the following Exponential Function given in the exercise:
If the value of Dependent variable is -3, then:
So, you must substitute that value of "x" into the function:
And now you must evaluate:
1. According the Negative exponent rule:
Then:
2. Simplifying, you get:
