1/8x - 5 < - 8 7x - 4 > 38
+ 5 +5 +4 +4
1/8x < -3 7x > 42
÷1/8 ÷1/8 ÷7. ÷7
x = 24 x > 6

Answer:

$x\in (-\infty,-24)\cup [6,\infty)$

Step-by-step explanation:

The given compound inequality is

$\frac{1}{8}x-5$ or $7x-4\geq 38$

Solve each inequality.

On solving first inequality we get

$\frac{1}{8}x-5$

Add 5 on both sides.

$\frac{1}{8}x-5+5$

$\frac{1}{8}x$

Multiply both sides by 8.

$x$ .... (1)

On solving second inequality we get

$7x-4\geq 38$

Add 4 on both sides.

$7x\geq 42$

Divide both sides by 7.

$x\geq 6$ .... (2)

Using (1) and (2) the value of x is either less than -24 or greater than or equal to 6.

$x\in(-\infty,-24)\cup [6,\infty)$

Answer:

-111

Step-by-step explanation:

substitute 5 in place of each x

-4(5)^2 - 3(5) + 4

then evaluate or type it into your calculator

13. y =<br> -x2 + 12x - 5<br> Axis of symmetry (aos):

marissa [1.9K]

Answer:

Slope = 24.000/2.000 = 12.000

When y = 0 the value of x is 5/-12 the line therefore crosses the x axis at x=-0.41667

x-intercept = 5/-12 = -0.41667

Algebra applications: find the value of x and y

Inga [223]

Answer : The value of x and y is 8 and 10 respectively.

Step-by-step explanation :

As we known that if two parallel lines are cut by a transversal line then consecutive interior angles are supplementary.

From the given figure we conclude that:

$5x-y+150=180$ ...........(1)

$5x-y=180-150$

$5x-y=30$ ............(2)

$5x+y+130=180$ ...........(3)

$5x+y=180-130$

$5x+y=50$ ...........(4)

Now we adding equation 2 and 4, we get the value of x.

$5x-y+5x+y=30+50$

$10x=80$

$x=8$

Now we are putting the value of x in 4, we get the value of y.

$5x+y=50$

$5(8)+y=50$

$y=50-40$

$y=10$

Therefore, the value of x and y is 8 and 10 respectively.

Y=arccos(1/x)<br><br> Please help me do them all! I don’t know derivatives :(

Stells [14]

Answer:

$f(x) = {sec}^{ - 1} x \\ let \: y = {sec}^{ - 1} x \rightarrow \: x = sec \: y\\ \frac{dx}{dx} = \frac{d(sec \: y)}{dx} \\ 1 = \frac{d(sec \: y)}{dx} \times \frac{dy}{dy} \\ 1 = \frac{d(sec \: y)}{dy} \times \frac{dy}{dx} \\1 = tan \: y.sec \: y. \frac{dy}{dx} \\ \frac{dy}{dx} = \frac{1}{tan \: y.sec \: y} \\ \frac{dy}{dx} = \frac{1}{ \sqrt{( {sec}^{2} \: y - 1}) .sec \: y} \\ \frac{dy}{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} } \\ \frac{d( {sec}^{ - 1}5x) }{dx} = \frac{1}{ |5x | \sqrt{25 {x }^{2} - 1} }\\\\y=arccos(\frac{1}{x})\Rightarrow cosy=\frac{1}{x}\\x=secy\Rightarrow y=arcsecx\\\therefore \frac{d( {sec}^{ - 1}x) }{dx} = \frac{1}{ |x | \sqrt{ {x }^{2} - 1} }$
