Answer:
x = -2.585
Step-by-step explanation:
You will have to plug this into your graphing calculator.
In y=, type 5(1/2)^x in the Y1 and type 30 in Y2.
When you hit 2nd trace and hit find intersections, you will get (-2.585, 30).
The answer is x = -2.585
The slope of the line is 1/3
The reflection of (-7, 2) across the y-axis is (-7, -2) (hope this helps ;3)
It's less than fifty eight tenths
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.
