Answer:
Step-by-step explanation:
Find the greatest common factor (GCF) of the 2 terms:
GCF is 5.
Factor out the GCF:
Rewrite as a difference of squares (
):
We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:
-2x + y = 1
y = 1 + 2x
4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3
y= 1 + 2(-1/3)
y = 1/3
Answer:
Option (1)
Step-by-step explanation:
Lines X and Y are intersecting at a point.
Two pairs of vertical angles have been formed at the point of intersection.
1). ∠1 and ∠3
2). ∠2 and ∠4
It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]
If line Y is rotated 5° clockwise about the point of intersection of both the lines,
∠1 and ∠3 both will increase by 5°.
Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).
Option (1) will be the answer.
Answer:
A. The CV is a relative measure of risk/return.
Step-by-step explanation:
The coefficient of variation of any investment, is used to measure and calculate the total risk of that investment with respect to its per unit expected return rate.
We can also define the coefficient of variation as a ratio of standard deviation to the expected value of an investment.
The answer is - A. The CV is a relative measure of risk/return.
