<u>w</u><u>=</u><u>-</u><u>1</u><u>.</u><u>5</u>

<u>w</u><u>=</u><u>2</u>

Answer:

Solution given:

\sqrt{2w²-19w+31}+2=7-2w

again

keep square root alone

\sqrt{2w²-19w+31}=7-2w-2

solve subtraction of 7-2

\sqrt{2w²-19w+31}=5-2w

Squaring on both side

(\sqrt{2w²-19w+31})²=(5-2w)²

2w²-19w+31=5²-2*5*2w+4w²

take terms one side

2w²-19w+31-25+20w-4w²=0

-2w²+w+6=0

2w²-w-6=0

doing middle term factorisation

2w²-(4-3)w-6=0

2w²-4w+3w-6=0

take common from each two term

2w(w-2)+3(w-2)=0

(w-2)(2w+3)=0

either

w=2

or

W=-3/2=-1.5

What is the equation of the line shown in this graph?<br><br><br><br> Enter your answer in the box
IgorLugansk [536]
This is a horizontal line at y = -3. If you want to find it mathematically, you could find the slope (y2-y1)/(x2-x1) and you would get 0 over 5, so you know the slope is zero. Pick either point and substitute the numbers into point-slope formula. I went with (3, -3) and got (y - -3) = 0(x-3). The right side is just 0, and if you subtract three from both sides to isolate y, you get the equation y = -3.
