Answer:
31 questions that are worth 7 points, 14 questions that are worth 2 points
Step-by-step explanation:
the variable s will stand for the number of 7 point questions, the variable t will stand for the number of two point questions.
7s + 2t = 245
s + t = 45
-------------
t = 45 - s
7s + 2(45 - s) = 245
7s + 90 - 2s = 245
5s + 90 = 245
5s = 155
s = 31
There are 31 questions that are worth 7 points.
7(31) + 2t = 245
217 + 2t = 245
2t = 28
t = 14
There are 14 questions that are worth 2 points
The slope of the interactive is 6
I'm not sure if you were supposed to add two numbers together to get five? If that's the case the answer would be 5/3. If it's not i'm sorry, I tried.
Answer:
Step-by-step explanation:
slope = (-5-(-1))/(0-(-2)) = (-4)/2 = -2
y+5 = -2(x-0)
y = -2x - 5
