C

Step-by-step explanation:

lets plug in the solution into each of the equations:

A:

2x-3y=4

2*(3/4)-3*(5/6)=4

3/2-5/2=4

-2/2=4

-14

B:

2x+3y=-4

2*(3/4)+3(5/6)=-4

3/2+5/2=-4

8/4=-4

2-4

C:

(2/3)x+3y=3

(2/3)(3/4)+3*(5/6)=3

6/12+5/3=3

0.5+2.5=3

3=3

D:

(2/3)x-3y=3

(2/3)(3/4)-3*(5/6)=3

6/12-(5/2)=3

1/2-2.5=3

-23

C is correct

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
