Ratio is 5girls:7boys with total 72 students
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys
New ratio is 3:4 with 48 boys
48➗4= 12
So for girls 3x12= 36
So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.
Answer:
the initial value -- f(0) -- results in a value of 1.5
Step-by-step explanation:
f(0) =
·
(any value raised to the power of zero equals one)
f(0) =
· 1
f(0) = 3/2 or 1.5
0.8 or 4/5
Both are correct, but in different form.
Your welcome.
Line y=mx+b has point (0,b).
If you've got poind (0,4) - you can write, that b=4.
So this is line y=mx+4
Now slope. You've got point (1,0), so for x=1, y=0. Substitute:
m * 1 + 4 = 0
m+4 = 0
m=-4
So equation of this line is: y=-4x+4
