Answer:
y=3.5x+4; A(_,5) B(10,_)
Step-by-step explanation:
.Find point A: Substitute y value given, solve for x:
.
5=3.5x+4
1=3.5x
1/3.5=x
0.2857=x
.
Point A=(0.2857,5)
.
Find point B: Substitute x value given, solve for y:
.
y=3.5(10)+4
y=35+4
y=39
.
Point B=(10,39)
.
Slope:
In slope intercept form y=mx+b, m=slope
.
Slope=m=3.5
.
The others are done the same way.
-10x-1 = 11 -9x
+10x +10x
-1 = 11 + x
-11 -11
-12 = x
x= -12
30-(increase/0.5)*2=sold
i*s=revenue
i*30-(i^2/0.5)*2=r
I=7.5=>r=0
i=7=>r=14
7/0.5=15 number of increases in the cost
So 10% of 12=1.2 divided by
2 to get 5% which is 0.6 so because it’s increasing the amount you do $12 + 0.6 =
$12.6 if you pay online
