What are the solutions of the equation x^4-9x^2+8=0? Use u substitution to solve.

vodka [1.7K]

Answer:

The answer is the second option

Step-by-step explanation:

Let u=x^2.

$( {x}^{2} ) {}^{2} - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}$

${u}^{2} - 9u + 8$

$(u - 1)(u - 8)$

$u = 1$

$u = 8$

Set this equal to x^2

${x}^{2} = 1$

$x = 1$

$x = - 1$

${x}^{2} = 8$

$x = 2 \sqrt{2}$

$x = - 2 \sqrt{2}$

Janice bought 3 movie tickets and 3 sodas and the total cost was $35.25. A ticket to the movie cost $5.25 more than a soda. How

Effectus [21]

Answer: a ticket to the movie costs $8.5

Step-by-step explanation:

Let x represent the cost of a movie ticket.

Let y represent the cost of a Soda.

Janice bought 3 movie tickets and 3 sodas and the total cost was $35.25. This means that

3x + 3y = 35.25 - - - - - - - - - -1

A ticket to the movie cost $5.25 more than a soda. This means that

x = y + 5.25

Substituting x = y + 25 into equation 1, it becomes

3(y + 5.25) + 3y = 35.25

3y + 15.75 + 3y = 35.25

6y = 35.25 - 15.75 = 19.5

y = 19.5/6 = 3.25

x = y + 5.25 = 3.25 + 5.25

x = 8.5

Find an equation for the perpendicular bisector of the line segment whose endpoints are (1,−8) and (9,2)

Len [333]

Answer: $y+3=-\frac{4}{5}(x-5)$

Step-by-step explanation:

For it to bisect the segment, we need to find the midpoint.

The midpoint is $\left(\frac{1+9}{2}, \frac{-8+2}{2} \right)=(5, -3)$

Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The slope of the given segment is $\frac{-8-2}{1-9}=\frac{5}{4}$ , so the slope of the perpendicular bisector is $-\frac{4}{5}$

Thus, the equation of the line in point-slope form is $\boxed{y+3=-\frac{4}{5}(x-5)}$
