F(x) = 112 - kx
f(-3) = 121
f(-3) = 112 - k(-3)
f(-3) = 112 + 3k
121 = 112 + 3k
121 - 112 = 3k
9 = 3k
9/3 = k
3 = k <===
Answer:
31
Step-by-step explanation:
-4+16+19=31
3 times 5 times 2.5 = $37.5
3 x 5 =15
15 x 2.5 =37.5
37.5 x 2 = 75 for both of them
I don't know if this is right or not, but that's how I would solve it!
Answer:
3
Step-by-step explanation:
There are 15 shells all together
there is 5 friends
15 divided by 5 is 3
Therefore the answer is three
Answer:
Option D.
Step-by-step explanation:
The given inequality is
.
To graph this inequality, we need to graph the corresponding linear equation;

The intercepts are
and
.
Plot these two points and draw a solid straight line through them.
We then test the inequality with the point (0,0).
.
.
This statement is false.
So we shade the lower half plane to obtain the graph in option D.
