Answer:
a. 1
b. 3
c. 9
Step-by-step explanation:
all you have to do is plug in 2 to the equations as x and solve for y!
a.
y = 7 - 3(2)
y = 7 - 6
y = 1
b.
y = (2)^2 -1
y = 4 -1
y = 3
c.
y = (18/(2))
y = 9
lmk if you need more of an explanation but that's pretty much all the work you need i think!! :)
