Answer:This is the only thing that i can tell u sorry but i hope this helps

Step-by-step explanation:

Subtract starting value minus final value

Divide that amount by the absolute value of the starting value

Multiply by 100 to get percent decrease

If the percentage is negative, it means there was an increase and not an decrease.

Percentage Decrease Formula

You can use the percentage decrease formula for any percent decrease calculation:

Percentage Decrease=Starting Value−Final Value|Starting Value|×100

Solve for x: 4x - 8 = 7x - 2<br>Anyone know the answer for this one?<br>Thanks!

Answer:

$\huge{ \fbox{ \tt{x = - 2}}}$

Step-by-step explanation:

$\underline{ \underline{ \mathfrak{Let's \: solve}}} :$

$\star{ \sf{ \: \: 4x - 8 = 7x - 2}}$

$\text{Step \: 1} : \sf{Move \: 7x \: to \: left \: hand \: side \: and \: change \: its \: sign}$

$\mapsto{ \sf{4x - 7x - 8 = - 2}}$

$\text{Step \: 2} : \sf{Move \: 8 \: to \: right \: hand \: side \: and \: change \: its \: sign}$

$\mapsto{ \sf{4x - 7x = - 2 + 8}}$

$\text{Step \: 3} : \sf{Collect \: like \: terms}$

$\sf{Like \: terms \: are \: those \: which \: have \: same \: base}$

$\mapsto{ \sf{ - 3x = - 2 + 8}}$

$\text{Step \: 4} : \sf{Calculate}$

$\underline{ \text{Remember!}} : \sf{The \: negative \: and \: positive \: integers \: are \: always \: subtracted \: but \: posses \: the \: sign \: of \: the \: bigger \: integer.}$

$\mapsto{ \sf{ - 3x = 6}}$

$\text{Step \: 4} : \sf{Divide \: both \: sides \: by \: - 3}$

$\mapsto{ \sf{ \frac{ - 3x}{ - 3} = \frac{6}{ - 3}}}$

$\text{ Step \: 4} : \sf{Calculate}$

$\mapsto{ \sf{x = - 2}}$

Hope I helped!

Best regards! :D

Which equation correctly shows that (x^2)^4=x^8?

UkoKoshka [18]

Answer: The answer is D

because x^2^4 power is x^8 and x^2*x^2*x^2*x^2 which is 2+2+2+2 which is x^8

Step-by-step explanation:

it is not C because it would be 4(c^2) which is 4x^2

it is not A because (x^2)(x^4) is 2+4 which is 6 so that means it would be x^6
