Y=4x−5
y=2x+3

is (4,11) part of the system

Yes

Step-by-step explanation:

If (4,11) is part of the system, it should satisfy both equations

y = 4x - 5

11 = 4(4) - 5

11 = 16 - 5

11 = 11 is a true statement

y = 2x + 3

11 = 2(4) + 3

11 = 8 + 3

11 = 11 is a true statement

Since (4,11) satisfies both the equations, it is part of the system

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
