Answer:
80 members
Step-by-step explanation:
Let the band members be= b and the chorale members= c
Then, according to question, b=c+30 and 
⇒
⇒
⇒
⇒
Now, substituting the value of b=c+30, we get
⇒
⇒
⇒
⇒
Therefore, 
Therefore, there are 80 members in the band.
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:
y = 2x+3
Answer:
the second one it is a function.
Answer:
127.75
Step-by-step explanation:
In this geometric series, it is clear that every number is half of the previous number. From that, we can continue on the series as shown below...
64+32+16+8+4+2+1+0.5+0.25
The series above is 9 total terms. We can add those together to get our answer.
64+32+16+8+4+2+1+0.5+0.25 = 127.75
25 i think. cause if there’s 100 people and the pilates looks like half (50) and spinning looks like half of 50 which would be 25.
