Answer:
Michael 24
Noor 42
Step-by-step explanation:
Ratio is 4:7
The initial quatity is 4x and 7x
After giving 3 shares the quatities are
4x - 3 and 7x + 3
Set equal to the new ratio
(4x - 3) / (7x + 3) = 7 / 15
Cross multiply
15(4x - 3) = 7(7x + 3)
Distribute
60x - 45 = 49x + 21
Add 45 to both sides
60x = 49x + 66
Subtract 49x from both sides
11x = 66
Divide both sides by 11
x = 6
Therefor
4x = 4*6 = 24 <–––– Michael's initial quantity
7x = 7*6 = 42 <–––– Noor's initial quantity

Answer:
<h2> An angle is formed by the two rays.</h2>
Answer:
y - 7 = -1/4(x-4)
Step-by-step explanation:
point slope is y-y₁=m(x-x₁)
(4, 7) and (8, 6)
I like to put it in the slope-intercept form first
so... 6 - 7/ 8-4 = -1/4 (slope)
6 = -1/4(8) + b
6/(-2) = -2/(-2) + b
-3 = b
so... y=-1/4x + -3
plug it in to point slope form
y - 7 = -1/4(x-4)
hopefully that made sense :)
