3x - 5 = 10 x = ______

Mathematics
1 answer:
Sphinxa [80]4 years ago
5 0

Answer:

3x - 5 = 10 x

The answer is: x=-\frac{5}{7}

Step-by-step explanation:

3x - 5 = 10x

First, Please, Add 5 to both sides, Which would be:

3x - 5 + 5 = 10x + 5

Second, Please, Simplify your answer, Which would be:

3x = 10x + 5

Third, Please, Subtract 10x from both sides, Which would be:

3x - 5 = 10x = 10x + 5 - 10x

Forth, Please, Simplify your answer, Which would be:

-7x = 5

Fifth, Please, Divide both sides by -7, Which would be:

\frac{-7x}{-7}=\frac{5}{-7}

Last and Finally, Simplify your answer, Which would be:

x=-\frac{5}{7}

I hope I helped :)

Find an equation of the line tangent to the curve √xy + 4y = 39 at the point (1,9)?
evablogger [386]
Find the derivative of the curve to find the line slope at the given point

sqrt(xy) + 4 dy/dx = 39

0.5(xy)^(-0.5) * (y + x dy/dx) + 4dy/dx=  0

No need to amplify simply plug in the given point ( 1,9)

0.5 ( 1 * 9)^(-0.5)* ( 9 + dy/dx) + 4dy/dx  = 0 

Solve for dy/dx

1/6( 9  + dy/dx)  = -4dy/dx

9 + dy/dx = -24 dy/dx

-25dy/dx = 9

dy/dx = -9/25

as your question implies , you know the rest of the steps.

A^3b^-2c^-1d if a=2 b=4 c=10 d=15 express as a reduced fraction
I am Lyosha [343]

\bf a^3b^{-2}c^{-1}d\implies \cfrac{a^3d}{b^2c}\qquad \begin{cases} a=2\\ b=4\\ c=10\\ d=15 \end{cases}\implies \cfrac{2^3\cdot 15}{4^2\cdot 10}\implies \cfrac{120}{160}\implies \cfrac{3}{4}
