Answer:
Line JK passes through points J(-4,-5) and K(-6, 3).
Line JK has form of y = mx + b
=> -5 = -4m + b
=> 3 = -6m + b
Subtract 2nd equation from 1st equation:
=> -8 = 2m
=> m = -4
Substitute back m = -4 into 1st equation:
=> -5 = -4(-4) + b
=> b = -21
Hope this helps!

Answer:
7/4
Step-by-step explanation:
I the average score is 750 and standard deviation ( sigma ) is 50 points, then score 700 - 800 is between (750 - 1 sigma) and (750 + 1 sigma).
That is 34.1 % + 34.1 % = 68.2 % of the whole population.
2,000 · 0.682 = 1.364
We expect 1,364 students to score between 700 and 800 points.
Answer:
164 19/50
Step-by-step explanation:
Rewrite 164.38 as 164 + 38/100. This, in turn, can be reduced to 164 + 19/50, or just
164 19/50.
I think it’s one solution
Because the first equation answer is 5y+15/4 the second answer is 5y-5/4
It ends up dividing by 4
Sorry if this is wrong
