Answer:
a. 1.75
Step-by-step explanation:
r values, or the correlation coefficient must be between -1 and 1, inclusive
-1 is a perfect negative correlation
0 is no correlation
+1 is a perfect positive correlation
1.75 is not between -1 and 1
Since the radicands (the number under the radical) are the same, add the coefficients and keep the radicand.
4√5 + 2√5 = 6√5
LETTER C
6x-12 = 2x-6
get like terms on the same side by adding/subtracting.
6x - 12 = 2x - 6
+ 12, -2x on both sides
6x - 2x = -6 + 12
4x = 6
divide all by 4
x = 1.5
to check your answer, plug in 1.5 for x and see if they are equal to one another.
6(1.5) - 12 = -3
2(1.5) - 6 = -3
