B. 9^2
explanation: 3^4 is equivalent to 3*3*3*3, which is 81
9^2 (9*9) also equals 81
C. 0.04 would be the correct answer.
I would say B. The mean is a good measure of central tendency.
I hope this helps!
Answer:
Both of these equations are in slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b
Where m is the y-intercept value.
y=-2x+5
y=-2x+20
The slope of the two equations are: m1=−2 and m2=−2
Step-by-step explanation:
Because the have the same slope it means the lines represented by these two equations are either parallel or are the same line.
The y-intercepts for the two lines are:b1 = 5 and b1=20
