35+(3n)
i hope this is the correct equation
X=2
y=-2-2x=-2-4=-6
so you choose a
Quite simply: 2+x
A constant is simply a number, something that does not change: here it's "2"
A variable can chage: here it's "x" - anything can be substituted for x
If we put those two together with a "+" sign, we get an expression: variables or contants (including multipled ones: such as 2x, which is a term) added to each other or subtracted from each other
<span> f(-4) all you need to do is plug in x = -4 into equation
so </span><span>If f(x)=-8-5x then
f(-4) = -8 - 5(-4)
f(-4) = -8 + 20
f(-4) = 12
answer
f(-4) = 12</span>
