<u>Understanding:</u>

The sum of 3 times a number (i'll define it as x) and 4 means 3x+4 is between -8 and 10 which means the value of 3x+4 is less than 10 and greater than -8. With that said, the inequality for that problem would be -8.

<u>Solving the problem:</u>

Now we know that -8, you can solve the problem by <em>subtracting 4</em> from each side then<em> dividing by 3.</em>

<em />

<em>-8-4</em>

<em />

<u>Final Answer:</u>

<u>-4</u>

F-1:
y=x+9
y-9=x
x-9=f-1
f-1(14)=14-9=5 f-1(5)=5-9=-4  f-1(-5)=-5-9=-14 f-1(25)=25-9=16
f(14)=14+9=24 f(5)=5+9=14 f(-5)=9-5=4 f(25)=25+9=34

How many 1-in. cubes can fit into a 2 by 4 by 2 in.<br>prism?​
wel

Answer:

16

Step-by-step explanation:

The dimensions of the base of the prism are 4" by 2"; the height is 2".

Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly.  We'd have a 3-dimensional prism with one layer of 1" cubes.

Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.
