12 + k/8
if k is 40
then 12 + 40/8
you do order of operation which division comes before additio.
40/8=5
12+5=17
the answer is 17
X+2<1
x<1-2
x<-1
-1 does not satisfy the inequality because though-1 is lesser than 0 but not lesser than -1.

Answer:
y = f(x) = ( x + 4 )( x - 1 )( x - 3 )
Step-by-step explanation:
Let the equation of the curve drawn on the graph is y = f(x)
We have to find an expression for f(x).
If we take y = 0, then there will be three values of x which are -4, 1 and 3.
Since, there is three solutions of f(x) = 0, hence, f(x) will be a three degree polynomial. and ( x + 4 ), ( x - 1 ) and ( x - 3 ) will be the three factor of the equation.
Therefore, y = f(x) = ( x + 4 )( x - 1 )( x - 3 ) is the required equation of the graph. (Answer)
