It would be 120 because 4% of 125 is 5, so you subtract 5 from 125 to get 120. I am pretty sure that's how you do it

125*\frac{100-4}{100}=125*\frac{96}{100}=\frac{125*24}{25}=5*24=120

Answer:

m^2/n

Step-by-step explanation:

The following laws of exponent are useful to this problem:

\displaystyle \large{ {(mn)}^{b} =  {m}^{b} {n}^{b}   } \\  \displaystyle \large{ {n}^{ - b} =   \frac{1}{ {n}^{b} }    }

We are given the expression:

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } }

Use the first law of exponent above.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{(8)( \frac{1}{4}) } {n}^{ ( - 4)( \frac{1}{4}) }   } \\  \displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } {n}^{  - 1}   }

Make sure to recall the important necesscary fundamental math such as operation with negative numbers/integers, basic division, fraction, etc.

From the expression, apply the second law of exponent to n^-1.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } ( \frac{1}{ {n}^{1} } )} \\   \displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =  {m}^{2 } ( \frac{1}{ {n} } )} \\

Multiply m in.

\displaystyle \large{( {m}^{8}  {n}^{ - 4} )^{ \frac{1}{4} } =   \frac{ {m}^{2} }{ {n} } }

Thus the answer is m^2/n.

Y=-3x-3<br><img src="https://tex.z-dn.net/?f=y%20%3D%20%20-%203" id="TexFormula1" title="y = - 3" alt="y = - 3" align="absmidd
Sedbober [7]

Let's find X. Since both equations are equal to y, they are equal to themselves.

-3x-3=-3; we just need to solve from here. -3x-3=-3; let's add 3 to both sides. -3x=0; this means that 0 is X.

Let's use a graph to check.

So, y is -3.

So, (0, -3) is when the two lines intersect and it's our solution.

What is the slope of a line that passes through (3,-7) and (-1,1)?
Rudiy27

\text{The slope formula:}\ m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{We have:}\\(3;-7)\to x_1=3;\ y_1=-7\\(-1;\ 1)\to x_2=-1;\ y_2=1\\\\\text{substitute:}\\\\m=\dfrac{1-(-7)}{-1-3}=\dfrac{1+7}{-4}=\dfrac{8}{-4}=-2

Answer: m = -2
