Write the equation of the line, given the y and x-intercepts:

kolezko [41]

Answer:

The answer to your question is: 161x + 17y - 391 = 0

Step-by-step explanation:

Data

y-intercept = 23 Get the points (0, 23)

x- intercept = 4.75 (4.75, 0)

4.75 = 17/4 (17/4, 0)

slope

m = (y2 - y1) / (x2 - x1)

m = (0 - 23) / (17/4 - 0)

m = -23 / 17/4

m = - 161 / 17

equation

(y - y1) = m (x - x1)

( y - 23) = -161 / 17 (x - 0)

y - 23 = -161/17 x

17(y - 23) = -161x

17y - 391 = -161x

161x + 17y - 391 = 0

Which expression is equivalent to square root 55x^7 y^6/11x^11 y^8? Assume x > 0 and y > 0.

morpeh [17]

The first step for solving this expression is to reduce the fraction with 11.
$\sqrt{ \frac{5 x^{7} y^{6} }{ x^{11} y^{8} } }$
Now reduce the fraction with $x^{7}$ .
$\sqrt{ \frac{5 y^{6} }{ x^{4} y^{8} } }$
Reduce the fraction one more time with $y^{6}$ .
$\sqrt{ \frac{5}{ x^{4} y^{2} } }$
To take the root of a fraction,, we must take the root of the numerator and denominator separately. This rule will change the expression to the following:
$\frac{ \sqrt{5} }{ x^{2} y}$
Since we cannot simplify this fraction any further,, the final answer is going to be $\frac{ \sqrt{5} }{ x^{2} y}$ .
Let me know if you have any further questions.

Solve for x (x/r)+(x/w)+(x/t)= 1

MissTica

x/r + x/w + x/t = 1

x (1/r + 1/w + 1/t) = 1

x = 1 / (1/r + 1/w + 1/t)

To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, rwt :

x = 1 / (1/r + 1/w + 1/t) • rwt / rwt

x = rwt / (rwt/r + rwt/w + rwt/t)

x = rwt / (wt + rt + rw)
