(1/27)^x-6=27 Could I please have a step by step as well? Much appreciated!

Andrei [34K]

Answer:

$x = 7$

Step-by-step explanation:

1) Use Division Distributive Property: (x/y)^a = x^a/y^a.

$\frac{1}{ {27}^{x - 8} } = 27$

2) Multiply both sides by 27^x - 8.

$1 = {27} \times 27^{1 + x - 8}$

3) Use the product rule: x^a x^b = x^a+b.

$1 = {27}^{1 + x - 8}$

4) Simplify 1 + x - 8 to x - 7.

$1 = {27}^{x - 7}$

5) Use Definition of Common Logarithm: b^a = x if and only if logb (x) = a.

$log_{27}1 = x - 7$

6) Use Change of Base Rule.

$\frac{ log_1 }{ log{27} } = x - 7$

7) Use rule of 1: log 1 = 0.

$\frac{0}{ log_{27}} = x - 7$

8) Simplify 0/log_27 to 0.

$0 = x - 7$

9) Add 7 to both sides.

$7 = x$

10) Switch sides.

$x = 7$

Therefor, the answer is x = 7.

UV has the endpoints U(0, 3) and V(–4, –5). Which shows the correct calculation for finding the x-coordinate of the point that p

Pavlova-9 [17]

Solution:

The end points of line segment UV is U(0, 3) and V(–4, –5).

The line segment is Partitioned by a point in the ratio of 4:3.Let that point be (x,y).

Formula for internal division

A line segment having end points $(x_{1},y_{1}) and (x_{2},y_{2})$ divided by a point (x,y) in the ratio of m:n.

$x=\frac{m x_{2}+nx_{1}}{m+n}, y=\frac{m y_{2}+ny_{1}}{m+n}$

$x=\frac{3\times 0+4 \times -(4)}{4+3}=\frac{-16}{7}$

(3x+4)^2=14 what are the solutions?

kherson [118]

$\bf (3x+4)^2=14\implies \sqrt{(3x+4)^2}=\pm\sqrt{14}\implies 3x+4=\pm\sqrt{14}
\\\\\\
3x=\pm \sqrt{14}-4\implies x=\cfrac{\pm \sqrt{14}-4}{3}\implies x=
\begin{cases}
\cfrac{\sqrt{14}-4}{3}\\\\
\cfrac{- \sqrt{14}-4}{3}
\end{cases}$

5×+3(×+4)=28 Show your work

kotykmax [81]

Answer:

x = 2

Step-by-step explanation:

Distribute the parenthesis on the left side

5x + 3x + 12 = 28

8x + 12 = 28 ( subtract 12 from both sides )

8x = 16 ( divide both sides by 8 )

x = 2
