Y=7x+1
*note that the first number is always the x.
so,
a) (0,?)
y=7(0)+1
y=1
(0,1)
b) (3,?)
y=7(3)+1
y=21+1
y=22
(3,22)
Answer:

Step-by-step explanation:
We have to find profit
.
This can be easily found using a formula for Profit given the Revenue and Cost.


Given that:


to find P(x) we can simply subtract R(x) by C(x).



and finally, after simplify this equation subtracting 6x by 2.3x.
this is the equation for the profit 

Answer:
x=30°
y=15°
z=150°
Step-by-step explanation:
2x+90+x=180°
2x=180°-90°
x=90/3
x=30
2y=x
y= 30/2
y=15°
2y°+z°=180°
2(15°)+z°=180°
z=180°-30°
z=150°
Hope it helps! :)
