X= -4
Work: 1^x/4^x=256
1^x= 256 * 4^x
In 1^x = In 256 * 4^x
xIn1 = In 256+ In4^x
x*0= xIn 4 + In 2^8
0= xIn 2^2 + 8In 2
x In 2^2 + 8In 2 =0
x* 2In 2 + 8In 2=0
2In 2x + 8In 2=0
2In 2x = -8In 2
x= -8/2
x=-4
Well, what's the graph of say y = 5x - 2?
the line will come by graphing that, y = 5x - 2... then we check the points that lie on either side of the line.
for example... the point (0,4) is a point that lies on the left-hand-side of that line..... so... let's check for its true/false value
(0, 4) x = 0, y = 4
y < 5x - 2
4 < 5(0) - 2
4 < 0 - 2
4 < -2 <--- now, is that true? is 4 lesser than -2? well, nope
so, that means the region where 0,4 lies, is the FALSE region, and we do not shade that part, so the part that needs shading is the other side.
The boundary line is dashed, meaning, it DOES NOT include the points lying on that line, but just anything off that, because y < 5x - 2, means "y" is less than, NOT EQUALS OR LESS, but just less.
check the picture below.
Answer:

Step-by-step explanation:
Given
Solid Shape = Cube
Edge = 2 feet
Increment = 5 feet per minute
Required
Determine volume as a function of minute
From the question, we have that the edge of the cube increases in a minute by 5 feet
<em>This implies that,the edge will increase by 5m feet in m minutes;</em>
Hence,

Volume of a cube is calculated as thus;

Substitute 2 + 5m for Edge

Represent Volume as a function of m

Answer: 14
Step-by-step explanation: 6 can go into 84 evenly, but if you do 84 divided by 6 it equals to 14
hope this helped you :)
