$f(x)= x^2+9\\\\for\ each\ x\in R\\\\x^2 \geq 0\ \ \ \Rightarrow\ \ \ x^2+9 \geq 9\ \ \ \Rightarrow\ \ \ f(x) \geq 9\\\\y_{min}=9\\ y_{max}\ \ \ \rightarrow\ \ \ not\ exist$

A line passes through the point (-2, 3) and has a slope of -2. What is the equation of the line?

Mrrafil [7]

Answer:

y = -2x -1

Step-by-step explanation:

slope intercept form is y = mx +b

m = slope, b = y intercept

point is given as ordered pair (x,y)

plug in slope into y=......

y= -2x+b

plug in the point

3 = -2 * (-2) + b

3= 4 +b subtract 4 on each side

b = -1

y = -2x -1

Which is the graph of y = 1/x?

irina1246 [14]

<u>answer:</u> the first graph

<u>explanation:</u>

it would not be the second one because it is a slope (y = mx + b) and so would be the third choice.

i don't think it would be the last one because it's going only up to 40. which the equation say only y = 1/x and it's not a big number equation.

hope this helps! ❤ from peachimin

i attached this image which is sorta similar to the the to this equation:

Simplify the following completely, show all work.<br><br>4 + ✓-27

V125BC [204]

Answer:

4+3i $\sqrt{3}$

Step-by-step explanation:

the $\sqrt{-27}$ needs to be simplified

first, I broke it down to $\sqrt{-1}$ and $\sqrt{27}$

$\sqrt{-1}$ simplifies to i ;and can be broken down to $\sqrt{9}$ and $\sqrt{3}$

$\sqrt{9}$ can be simplified further to 3

Now all you have to do is put it together

4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)
