Answer:
y=5x+29
Step-by-step explanation:
1. find slope
y2-y1/x2-x1
9--6/-4--7= 15/3=5
2. substitute x and y
(-4, 9)= 9=5(-4)+b
9=-20+b
29=b
3. put it together
y=5x+29

Answer: 
Step-by-step explanation:
Do you mean ![2[(12+2x)+(15+2x)]=74](https://tex.z-dn.net/?f=2%5B%2812%2B2x%29%2B%2815%2B2x%29%5D%3D74)
? In that case just finish things inside the bracket first then multiply 2 inside.
Then multiply 2 inside the bracket.
Move 54 to other side then we get,

Answer:
36
Step-by-step explanation:
Let's say Leslie starts with x oranges.
The first person buys 1/3 of the oranges, leaving behind 2/3 x.
The second person buys 4 oranges, leaving behind 2/3 x − 4.
The third person buys 1/4 of the remaining oranges, leaving behind:
3/4 (2/3 x − 4)
This amount equals 15. Solving for x:
15 = 3/4 (2/3 x − 4)
20 = 2/3 x − 4
24 = 2/3 x
36 = x
