Answer:
20%
Step-by-step explanation: The percent of error formula is |(theoretical value-actual value)/actual value|=percent of error. Substitute the values in. |(2.8-3.5)/3.5|=|(-0.7)/3.5|=0.2. The percent equal to 0.2 is 20%.
The slope of the given line is m = 8
You can think of m = 8 as m = 8/1. Flip the fraction to get 1/8 and then flip the sign to get -1/8
Answer: -1/8
Note: Multiplying the original slope (8) and the perpendicular slope (-1/8) will lead to the result of -1. This applies to any two perpendicular lines as long as one of the lines isn't vertical.
Answer:
Step-by-step explanation:
Let's start by using distributive multiplication:
So:
Grouping like terms:
Now, is equal to:
In this sense:
In order to satisfied the equality:
Hence, from (1), let's solve for a:
And from (2), let's solve for b:
Let's verify the result evaluating the values of a and b into the original equation:
As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
(0, 3) so b = 3 and slope = -5/4
equation
y = -5/4x + 3
answer
B. y = -5/4x + 3
