The expression we have is:
Step 1. Use the binomial square formula:
Applying this formula to the first binomial squared:
Step 2. Apply the formula for the square of a binomial to the second binomial:
In this case, we have some operations to solve before we move on to isolating x. So we solve the operations:
Step 3. Move the terms that are not x squared to the right side of the expression. Remember that when we move one term from one side of the equation to the other, the term must change its sign. We get the following:
Step 4. Combine like terms and arrange terms in order from the greatest exponent to the lowest and leave the independent term at the end:
And that is the final result, which is option A.
Answer: Option A.
Yes because if a negative sign is in a fraction doesnt matter where, it still show that the fraction is negative
3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.
Answer:
Tables are essentially the source for all the charts. They are best used for comparison, composition, or relationship analysis when there are only few variables and data points. It would not make much sense to create a chart if the data can be easily interpreted from the table.
The tables help us to compare the values of those two sets of the data that have been presented in different ways.
Answer:
The slope of the given line is -4
Step-by-step explanation:
The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m = 
In the given figure
∵ The line passes through the points (-6, 5) and (-4, -3)
∴ x1 = -6 and y1 = 5
∴ x2 = -4 and y2 = -3
→ Substitute them in the formula of the slope above
∵ m = 
∴ m = 
∴ m = 
∴ m = -4
∴ The slope of the given line is -4
