(7x-6y)+(x+y) add them because sum means you're doing addition...
7x-6y+x+y
8x-5y
(Remember that x=1x and y=1y)
Y=1/4x - 1 since the y intercept is at -1
Answer:
Step-by-step explanation:
Let x be the number of students,
Y be profits, Rate per student is $550, initial investment is 25000
From the expression , denotes the constant value.
The initial investment is our constant value.
, Initial investment is the expenses hence
Therefore, our equation will be:-
Answer:
y=x-4
Step-by-step explanation:
y= mx+b Slope intercept form
b= y intercept= -4
m= slope=1
y= 1x-4= y=x-4
