Answer:
x = ±√3
Step-by-step explanation:
In order to avoid extraneous answers, I like to work these by transforming to an expression equal to zero.
__
If you do this the usual way, by clearing fractions to start, you will get an extraneous solution of x=3.
Answer: 68
Step-by-step explanation:
The formula is
A=p (1+r)^t
A future value?
P present value 25000
R interest rate 0.03
T time 9 years
A=25,000×(1+0.03)^(9)
A=32,619.33
9. 1/2 & 4/8
10. 1/3 & 4/12
11. 2/4 & 1/2
12. 5/10 & 10/20
13. 2/6 & 4/12
14. 4/6 & 8/12
Answer:
a. rotation; then reflection across x
Step-by-step explanation:
The transformation shown is a reflection across the y-axis.
The first part of each answer choice is a rotation 180°. That rotation is fully equivalent to reflection across both the x- and y-axes, in either order. In order to have a net effect of reflection across the y-axis, the reflection across the x-axis must be cancelled--by another reflection across the x-axis.
The reflection across y shown is equivalent to ...
rotation 180° followed by reflection across the x-axis.
