<span>8x = 2y + 5
3x = y + 7 so y = 3x - 7
substitive </span>y = 3x - 7 into 8x = 2y + 5 

8x = 2y + 5 
8x = 2(3x - 7) + 5 
8x = 6x - 14 +5
2x = -9
x = -4.5

y = 3x - 7
y = 3(-4.5) - 7 = -13.5 - 7 = -20.5

solutions (-4.5, -20.5)

Answer:

none

Explanation:

Fill in each option for x individually.

I)     9 \leq -10 - 4(-1)  

II)    9 \leq -10 - 4(-3)  

III)   9 \leq -10 - 4(-2)

Then, simplify the right side of each inequality.

I)    9 \leq -6

II)   9 \leq 2

III)  9 \leq -2

Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.

Which correlation should be used to measure the relationship between gender and grade point average for a group of college stude
Alecsey [184]
I believe the correct answer would be A. The best correlation to use to measure the relationship between gender and grade point average for a group of college students would be the point-biserial correlation. It is coefficient that is used when a variable is dichotomous or that the variable is part of a whole set. It is used in measuring the direction of the correlation that is present between a dichotomous variable and a continuous variable. From the  question, the dichotomous variable would be the grade point average for a group of college students while the other variable is the continuous one.
