Y=3x+8

Y=-2x-2

------------subtract

0 = 5x +10

5x = -10

x = -10/5

x = -2

Y=3x+8

Y= 3(-2) + 8

Y=-6 + 8

Y = 2

answer: (-2,2)

What is the length of line segment AB? 1 inch v3 inches 4 inches 475 inches

drek231 [11]

Answer:

$AB=\sqrt{3}\ in$

Step-by-step explanation:

The correct question is

The diagonal of rectangle ABCD measures 2 inches in length.

What is the length of line segment AB?

The picture of the question in the attached figure

we know that

In the right triangle ABD

$cos(30^o)=\frac{AB}{BD}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(30^o)=\frac{AB}{2}$

Remember that

$cos(30^o)=\frac{\sqrt{3}}{2}$

$\frac{AB}{2}=\frac{\sqrt{3}}{2}$

$AB=\sqrt{3}\ in$

Please... I... need... HELP

Alja [10]

Here!
(x+4)+(x+2)+(x+5)= (x+1)+(x+1)+(x+3)+(x+3)
First you want to write the whole equation out. Make each perimeter equal to each other.
Then add both sides separately.
(x+4)+(x+2)+(x+5)
=3x+11

and

(x+1)+(x+1)+(x+3)+(x+3)
=4x+8

Now that you've simplified each side, solve like a normal equation.
3x+11 = 4x+8
-3x -3x
11 = x+8
-8 -8
3=x

Can you help me solve this please

OLga [1]

Answer:

-22+27i

Step-by-step explanation:

$i = \sqrt{ - 1} \\ (3 - 4i)( - 6 + i) \\ = (3 - 4 \sqrt{ - 1} )( - 6 + \sqrt{ - 1} ) \\ = 3( - 6 + \sqrt{ - 1)} - 4 \sqrt{ - 1} ( - 6 + \sqrt{ - 1} ) \\ = - 18 + 3 \sqrt{ - 1} + 24 \sqrt{ - 1} - 4 \\ = - 22 + 27 \sqrt{ - 1} \\ putting \: \: \: \sqrt{ - 1 } = i \\ = - 22 + 27i$

Hope it helps.
