Here's our data:
15 questions total
Total number of points: 100
Spelling questions are worth 5 and represented by x
Vocab questions are worth 10 and represented by y
Therefore:
x+y=15
5x + 10y= 100
So:
x+y=15
x= 15-y
5x +10y =100
5(15 -y) +10y =100
75 -5y +10y =100
75 +5y = 100
5y=25
y=5
x +y=15
x+5=15
x=10
There are 10 spelling questions and 5 vocab questions
Step-by-step explanation:
I am not able to see the whole graph, but what I could see is that
domain=22
range=11
the x-intercept is there is no x-intercept!
y-intercept is 2
max is 10
minimum is 1
I am so sorry! But if you let me know about the decreasing and increasing values like that are they asking for? The greatest places in the graph where it increases or decreases?
Hope that helps :)
<span>President has 19 options
Vice President has 18 options (19 - 1 president)
Secretary has 17 options (19 - president and vice president)
