Answer:

$x=43$

Step-by-step explanation:

Given equation:

$25=5(3x-4)^{\frac13}$

Divide both sides by 5:

$\implies 5=(3x-4)^{\frac13}$

Cube both sides:

$\implies 5^3=((3x-4)^{\frac13})^3$

$\implies 125=(3x-4)^{\frac33}$

$\implies 125=(3x-4)^1$

$\implies 125=3x-4$

Add 4 to both sides:

$\implies 129=3x$

Divide both sides by 3:

$\implies x=43$

Answer:

x = 43

Step-by-step explanation:

25 = 5∛(3x - 4)
On cubing the entire expression :
15625 = 125(3x - 4)
3x - 4 = 125
3x = 129
x = 43

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select t

Pepsi [2]

Answer:

Step-by-step explanation:

Two lines are perpendicular if the first line has a slope of $m$ and the second line has a slope of $\frac{1}{-m}$ .

With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:

$5x - 2y = -6$

$-2y = -5x - 6$

$y = \frac{5}{2}x + 3$

We now know that $m = \frac{5}{2}$ for the first line, which means that the slope of the second line is $m = \frac{-2}{5}$ . With this, we have the following equation for our new line:

$y = \frac{-2}{5}x + C$

where $C$ is the Y-intercept that we now need to determine with the coordinates given in the problem statement, $(5, -4)$ :

$y = \frac{-2}{5}x + C$

$(-4) = \frac{-2}{5}(5) + C$

$-4 = -2 + C$

$C = -2$

Finally, we can create our line:

$y = \frac{-2}{5}x - 2$

$5y = -2x - 10$

$2x + 5y = -10$

on a scale drawing, 5 metres is represented by 4 centimetres. write the scale as a ratio in it's simplest form.

ryzh [129]

Answer:

The scale factor is 1:125

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which consists of multiplying or dividing by a constant factor. We use scaling when representing geographic locations on a map.

On a scale drawing, a distance of 5 meters = 500 cm is represented by 4 centimeters. The scale factor is usually represented as a ratio of the smallest to the biggest magnitude:

$\frac{4}{500}=\frac{1}{125}$

The scale factor is 1:125
