Remember, you can do anything to an equation as long as you do it to both sides

and when multiply or divide by a negative in inequalities, flip the direction of the sign

12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4

-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4

Answer:

The answer to your question is slope = 0; y = -2

Step-by-step explanation:

Data

A (-2, -2)

B (2, -2)

Process

1.- Calculate the slope

m = (-2 - (-2)) / (2 - (-2))

m = ( -2 + 2) / (2 + 2)

m = 0/4

m = 0

2.- The equation of the line is

y - y1 = m(x- x1)

y - (-2) = 0(x - (-2))

y + 2 = 0

y = -2

Answer:

0.21

Step-by-step explanation:

The given expression is :

$0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}$

We need to solve it.

We know that,

$\sqrt{0.09}=0.3\ and\ \sqrt{0.05}=0.223$

So,

$0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}=0.5\times 0.3-2\times 0.22+0.5\\\\=0.21$

$=\dfrac{21}{100}$

So, the value of the given expression is equal to 0.21.

Find the inverse of the function f(x)=5x-6/x+2

Naily [24]

Answer:

$f^{-1}(x)=\dfrac{2x+6}{5-x}$

Step-by-step explanation:

Swap x and y, then solve for y.

$x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}$
