Is y = 0.5x - 1 a liner function

Mama L [17]

$\text{Yes, it is a linear function}\\\\\text{The reason why it's a linear function is because there is a constant change}\\\\\text{The constant change would be your slope, and the slope in this case}\\\text{is 0.5}\\\\\text{If you plug this equation in a graph, it would be a straight line forever}\\\\\text{If you want to know if a line is linear, just check the slope to see if it's}\\\text{constant.}$

rosijanka [135]

Answer: y=-2/5x+2

Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2

$- 1 = - 3 - 4 \cos(4θ + \frac{2\pi}{3} ) \\ - 1 + 4 \cos(4θ + \frac{2\pi}{3} ) = - 3 \\ 4 \cos(4θ + \frac{2\pi}{3} ) = - 3 + 1 \\ 4 \cos(4θ + \frac{2\pi}{3} ) = - 2 \\ \cos(4θ + \frac{2\pi}{3} ) = - \frac{1}{2} \\ \cos(4θ + \frac{2\pi}{3} ) = - \frac{1}{2} \\ \cos(2\pi - (4θ + \frac{2\pi}{3} )) = - \frac{1}{2} \\ 4θ + \frac{2\pi}{3} = arccos( - \frac{1}{2} ) \\ \cos( \frac{4\pi}{3} - 4θ) = - \frac{1}{2}$

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo

Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, number of words she can type = $\frac{90}{\frac{1}{60}}$

= 90×60

= 5400 words per hour

If she types $2.6\times 10^5$ words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= $5400\times x$

Therefore, $5400\times x =2.6\times 10^5$

$5400x=260000$

$x=\frac{260000}{5400}$

$x=48.15$ hours

Therefore, Dana types $2.6\times 10^5$ words in 48.15 hours.

What is the LCD of the following rational expressions?

Aloiza [94]

$\dfrac{x}{x+1} \ , \ \dfrac{7x}{x-1}$

$\dfrac{x (x -1)}{(x+1)(x -1)} \ , \ \dfrac{7x(x+1)}{(x-1)(x+ 1)}$

<u>We know that (a + b)(a - b) = a² - b²:</u>

$\dfrac{x (x -1)}{x^2 - 1}} \ , \ \dfrac{7x(x+1)} {x^2 - 1}$

Answer: LCD = ( x + 1) (x - 1)
