Answer:
[7 6]
[7 4]
Step-by-step explanation:
Company A: y=6x+12
Company B: y=5x+15
x is the variable for how many windows they clean.
A:
y=6(8)+12
y=48+12
y=60
B:
y=5(8)+15
y=40+15
y=55
Company B charges less for 8 windows.
A:
y=6(6)+12
y=36+12
y=48
B:
y=5(6)+15
y=30+15
y=45
Company B charges $3 less than Company a to clean 6 windows.

Answer:
there are no solutions
Step-by-step explanation:
8m-6+8-3m=5m-2
8m-3m-5m-6+8-2=0
as,
8m-8m+8-8=0
0=0
2tan(x)
i. take the 2 out
ii. derivative of acos is -sin
iii. derivative of In is -ve inverse
so we have 2 times sin(x)/cos(x) hence 2tan(x)
