A. 2x2 – 4x – 6

Looking at the diagram, there two positive x's to the power of 2, and there are four negative x and six minus signs. Inspecting it and adding all the same terms, you will get the quadratic expression 2x^2 - 4x - 6.

James Charle’s net worth is $30,000,000 . Jeffree Star’s net worth is $50,000,000. What is the difference in their net worth?

noname [10]

Hey there!

(Funny question btw, lol)

All we have to do is subtract the 2 numbers...

$50,000,000 - $30,000,000 = $20,000,000

Therefore, the difference is $20,000,000

Hope this helps you!

God bless ❤️

Solve 2z = modulus of z + 2i

Marta_Voda [28]

I assume the equation is

$2z=|z|+2i$

then let $z=x+iy$ .

$2x+2iy=\sqrt{x^2+y^2}+2i$

$2x+2i(y-1)=\sqrt{x^2+y^2}$

The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

$2(y-1)=0\implies y=1$

Then

$2x=\sqrt{x^2+1}$

$4x^2=x^2+1$

$3x^2=1$

$x=\pm\dfrac1{\sqrt3}$

but again we omit the negative solution, so that

$\boxed{z=\dfrac1{\sqrt3}+i}$

M ∠1 = ? 40 50 130 pls help!!

snow_tiger [21]

Answer:

Step-by-step explanation:

In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.

Lets find Angle 2 first.

First of all, the angle between angle 40 and 90 can be found easily.

That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:

40 + x + 90 = 180

Lets solve for "x":

40 + x + 90 = 180

130 + x = 180

x = 180 - 130

x = 50

Now, This angle (50) and Angle 2 are same [vertical angles]

So,

Angle 2 = 50

Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:

90 + Angle 1 + Angle 2 = 180

90 + Angle 1 + 50 = 180

Angle 1 + 140 = 180

Angle 1 = 180 - 140

Angle 1 = 40
