solve for x and y:
28x-49y=35
4x-7y=5
a. the solution is (0, 0).
b. there are an infinite number of solutions.
c. x=3,y=1
d. there is no solution.

D no solution

Step-by-step explanation:

the first one is wrong because if they were both 0 than they would have to equal 0

the second one is wrong because no number works

the third one is wrong because it works on the second one but when you plug it into the first equation you get 95 = 35 which is incorrect.

D is the correct choice.

- 70

this is the answer for you hope it

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
