Answer: 
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): Dot was discarded near "7.".
<u>STEP 1: </u>
Simplify 
<u>The equation at the end of step 1:</u>
<u>Multiplying exponential expressions:</u>
2.1 
multiplied by 
Final result is
3n = 1/81; divide both sides by 3 to isolate n:
3n/3 = 1/81 divided by 3. Remember that when you divide, you use the reciprocal and multiply instead!!
n = 1/81(1/3) = 1/243. Now plug 1/243 back in for n, and 3/243 is equivalent to 1/81
Answer:
slope = -1
Step-by-step explanation:
parallel lines have the same slope,
y = -x – 4
=> y = -1(x) -4
↑ slope
y = mx + b
↑ slope
Answer:
Step-by-step explanation:
a). Given equation is y = 3x - 4
Table for the input-output values is,
x -1 0 1 2 3
y -7 -4 -1 2 5
Now we can plot these points on the graph (graph attached).
b). Equation is y = -2x + 3
Table for the input-output values will be,
x -1 0 1 2 3
y 5 3 1 -1 -3

What is the similarity ratio of △WXY to △GEF?
Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
If two triangles are similar, their similarity ratio is the ratio between a side length in the first triangle and the corresponding side length in the second triangle.
