Choose a system of equations with the same solution as the following system:
4x − 2y = 6
2x + y = 5
a.−4x − 2y = 10
2x − 3y = 21
b.4x + 2y = 10
10x + y = 21
c.−4x − 5y = −1
2x − 6y = 10
d.3x + 2y = 6
9x + y = 17

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

hope this ! have a great day.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
