PLEASE ANSWER

A. (-4, 5)
B. (8, 1)
C. (3, -2)
D. No solution
E. Infinite number of solutions

C. (3, -2)

Step-by-step explanation:

x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y

3x - 5y = 19 replace x with 1 - y

3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms

-8y = 16

y = -2 if y is 2 then x is

x + y = 1 ➡ x +(-2) = 1 and x = 3

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

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
