(√ x+2) -2(√ x+2)-3=0 The square root only contains the x, what is the value of x?

Graph of y=(x-3)(x+4)

tekilochka [14]

Answer:

For graph refer to attachment .

Step-by-step explanation:

We need to plot the graph of a given function . The given function is ,

$\rm\implies y = ( x - 3)(x+4)$

When we will simplify the RHS term we will get ,

$\rm\implies y = x( x + 4 ) -3(x + 4 )$

Simpify the brackets ,

$\rm\implies y = x^2 + 4x -3x -12$

Add like terms , we have ,

$\rm\implies \boxed{\blue{\rm y = x^2+x -12}}$

From the equation :-

The graph will cut x axis at 3 and -4 as x = 3 and -4 are the roots of the equation .
The graph will cut y axis at (0,-12)
The vertex of the graph will be (-0.5,-12.5)

For the graph refer to attachment .

Answer:

a. plane DEA

Step-by-step explanation:

A plane can be named by naming any 3 non-collinear points in the plane, or by using the plane's name as indicated in the drawing.

Here, points in the plane are A, D, E, F, with DEF all on the same line. So A plus any two points from the line will constitute a name for the plane. Also, this plane is identified with a script M that can be used to name the plane.

M is not an answer choice, but DEA is. So, the appropriate choice is ...

plane DEA

__

F is a point, not a plane name. C is not on the plane, so cannot be used to name it. 'k' is a line name, not a plane name.

In the equation -3(y-2)2/3+29=-19, the values of y are

Elodia [21]

See attached explanation.: Answer: y=26 or

Step-by-step.(−3(y−2))(2)3+29=−19
Step 1: Simplify both sides of the equation.(−3(y−2))(2)3+29=−19Simplify: −2y+4+29=−19 (Distribute)(−2y)+(4+29)=−19 (Combine Like Terms)−2y+33=−19−2y+33=−19

Step 2: Subtract 33 from both sides.−2y+33−33=−19−33−2y=−52

Step 3: Divide both sides by -2.−2y−2=−52−2y=26Answer: y=26
