X-b=a solve for x please show work tnx

1 answer:

3 0

Okay so, you would just have to simply do one step for this literal equation.

x-b=a
+b +b
x=a+b

You would just have to add b to both sides to cancel out the -b on the left side because you have to isolate x to solve for x. So you add b to both sides, and then the -b gets cancelled out and the right side becomes a+b.

So x = a+b

Hope this helped!

Some information about a direct variation is given in the table below. If the equation

postnew [5]

Answer:

Step-by-step explanation:

y = kx ;

k = $\frac{y}{x}$ ; x = $\frac{y}{k}$

~~~~~~~~~~~~~

k = $\frac{1}{2}$ ÷ 1 = $\frac{1}{2}$

$y_{1}$ = $\frac{1}{2}$ × ( - 8 ) = - 4

$y_{2}$ = $\frac{1}{2}$ × ( - 4 ) = - 2

$y_{3}$ = $\frac{1}{2}$ × 2 = 1

$x_{5}$ = $\frac{1}{3}$ ÷ $\frac{1}{2}$ = $\frac{2}{3}$

$x_{6}$ = - $\frac{1}{4}$ ÷ $\frac{1}{2}$ = - $\frac{1}{2}$

$x_{7}$ = 0

( x , y ) : ( - 8 , - 4 ), ( - 4 , - 2 ), ( 2 , 1 ), ( 1 , $\frac{1}{2}$ ), ( $\frac{2}{3}$ , $\frac{1}{3}$ ), ( - $\frac{1}{2}$ , - $\frac{1}{4}$ ), ( 0 , 0 )

Determine an expression for dy dx given that x = sin3 (t)andy = cos3 (t)

shtirl [24]

Answer:

$\frac{dy}{dx} =-\sqrt[3]{\frac{y}{x} }$

Step-by-step explanation:

Recall that using the chain rule we can state:

$\frac{dy}{dt} =\frac{dy}{dx}*\frac{dx}{dt}$

and therefore solve for dy/dx as long as dx/dt is different from zero.

Then we find dy/dt and dx/dt,

Given that

$x=sin^3(t)\\dx/dt = 3 sin^2(t)* cos(t)$

And similarly:

$y=cos^3(t)\\dy/dt=-3\,cos^2(t)*sin(t)$

Therefore, dy/dx can be determined by the quotient of the expressions we just found:

$\frac{dy}{dx} =\frac{dy/dt}{dx/dt} =\frac{-3\,cos^2(t)*sin(t)}{3\,sin^2(t)*cos(t)} =-\frac{cos(t)}{sin(t)}$

now notice that we can find $cos(t) = \sqrt[3]{y}$ from the expression for y,

and $sin(t) = \sqrt[3]{x}$ from its expression for x.

Therefore dy/dx can be written in terms of x and y as:

$\frac{dy}{dx} =-\frac{cos(t)}{sin(t)}=-\sqrt[3]{\frac{y}{x} }$

What is the square root of 72 simplified

Ket [755]

Answer: 6√2

Step-by-step explanation:

8 × 9 is 72.

8 can be simplied to 4 × 2.

And 4 can be simplified to 2 × 2.

So far there are three 2s and a 9.

9 can be simplified down to 3 × 3.

Theres a pair of 2s and a pair of 3s, so you multiply 2 × 3 and thats 6 so you put 6 on the outside of the radical. Theres one 2 leftover from all the simplifying so that goes inside the radical to give you 6√2
