2w-1 divided by 5+w+2=2w
FromTheMoon [43]

Answer:

(2w-1)/5+w+2=2w

We simplify the equation to the form, which is simple to understand  

(2w-1)/5+w+2=2w

Reorder the terms in parentheses

( + 0.4w-0.2)+w+2=2w

Remove unnecessary parentheses

+ 0.4w-0.2+w+2=2w

We move all terms containing w to the left and all other terms to the right.  

+ 0.4w+1w-2w=0.2-2

We simplify left and right side of the equation.  

-0.6w=-1.8

We divide both sides of the equation by -0.6 to get w.  

w=3

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are
Galina-37 [17]

Answer:

B' = (-3,6)

Step-by-step explanation:

Given

A(4,5)

B(0,5)

C(3,-1)

<em>Translation: 3 units left and 1 unit right</em>

Required

Determine the new coordinates of B

Write out the coordinates of B

x = 0

y = 5

When a function is shifted to the left, we have to subtract the unit from the x value of the function;

<em>Shifting by 3 units left, the new x becomes </em>

<em />New\ x = 0 - 3<em />

<em />New\ x = -3<em />

<em />

When a function is shifted upward, we have to add the unit to the y value of the function;

<em>Shifting by 1 unit up, the new y becomes </em>

New\ y = 5 + 1

New\ y = 6

Hence, the new coordinates of B is

B' = (-3,6)

Find all complex solutions of the equation z⁴-1-i=0.​
bulgar [2K]

Answer:

Step-by-step explanation:

hello :

z⁴=1+i      given : z² = t    t is the complex number  so :   z⁴= (z²)² =t²

solve for  t  this equation : t² = 1+i

if : t = x+iy     t² =(x+iy)² = x²+2xiy+(iy)² =x²-y²+2xyi ......     (  i² = -1)

t² = 1+i  means : x²-y²+2xyi = 1+i

you have this system :   x²-y² = 1.....(*)

                                      2xy  = 1.....(**)

slve for   x  and y    you ca add this equation :   ....(***)

( use : t² = 1+i

/t²/ = /1+i/   so :/t/² = /1+i/ .... (√(x²+y²))²=√(1²+1²) =√2  means x²+y² = √2)

the system is :   x²-y² = 1.....(*)

                         2xy  = 1.....(**)

                         x²+y² = √2 ....(***)

add (*) and (***) : 2x²= 1+√2

x² = (√2+1)/2

substrac  (*) and (***)  you have : y² = (√2-1)/2

use (**) the proudect  xy is positif (same sign)  so :

x=√( (√2+1)/2)  and  y = √( (√2-1)/2)   so :  t1 =√( (√2+1)/2)+i√( (√2-1)/2)  

x= -√( (√2+1)/2)  and  y = -√( (√2-1)/2) so :t2= -t1

same method for equation : z² =t1  ..(2 solution )  and z² = t2..(2 solution )

Solve x2 - 8x - 9 = 0.<br><br> Rewrite the equation so that it is of the form <br> x2 + bx = c.
stira [4]
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
X1 = (8-10)/2 = -1
X2= (8+10)/2= 9
