Please help asap! This is due in an hour.

GalinKa [24]

We find the common factor and reduce the fraction:

10/15 = (10/5) / (15/5) = 2/3

15/20 = (15/5) / (20/5) = 3/4

2/6 = (2/2) / (6/2) = 1/3

2/8 = 1/4

3/12 = 1/4

3/9 = 1/3

4/6 = 2/3

5/15 = 1/3

5/20 = 1/4

6/8 = 3/4

6/9 = 2/3

9/12 = 3/4

X+½x+7y=0 what is the value of y=?

Ganezh [65]

Answer:

$\frac{-3x}{14}$

Step-by-step explanation:

$x+\frac{1}{2}x+7y = 0\\$

$1.5x + 7y = 0$

$7y = -1.5x$

$y = \frac{-1.5x}{7}$

$= \frac{-3x}{14}$

Hope this helps :)

The square root of x minus two plus 8 equals x

FrozenT [24]

Step-by-step explanation:

$\sqrt{x - 2 + 8} = \sqrt{x + 6} = x$

${( \sqrt{x + 6} })^{2} = {x}^{2}$

$x + 6 = {x}^{2}$

${x}^{2} - x - 6 = 0$

$(x - 3)(x + 2) = 0$

x = 3 or x = -2 we dont use the (-2) because we have a sqrt

So x =3

Given the function f(x) = -2c+cx-x^2, and f^-1(5) = -1, find c

AnnZ [28]

Answer:

$c=-2$

Step-by-step explanation:

We are given the function:

$f(x) = -2c + cx - x^2$

And that:

$\displaystyle f^{-1} (5) = -1$

And we want to determine the value of <em>c</em>.

Recall that by definition of inverse functions:

$\displaystyle \text{If } f(a) = b, \text{ then } f^{-1}(b) = a$

So, since f⁻¹(5) = -1, then f(-1) = 5.

Substitute:

$f(-1) = 5 = -2c + c(-1) - (-1)^2$

Simplify:

$5 = -2c - c - (1)$

Combine like terms:

$6 = -3c$

And divide. Hence:

$c = -2$

In conclusion, the value of <em>c</em> is -2.
