Please answer this fast in two minutes
Elden [556K]

Answer:

<h2>v=(13,-3)</h2>

solution,

- 2 =  \frac{x - 17}{2}  \:  \\  - 2 \times 2 = x - 17 \\  - 4 = x - 17 \\  - x =  - 17 + 4 \\  - x =  - 13 \\ x = 13 \\  \\ 7 =  \frac{y + 17}{2}  \\ 14 = y + 17 \\  - y = 17 - 14 \\  - y = 3 \\ y =  - 3

Therefore,

V=(13,-3)

Hope this helps...

Good luck on your assignment..

What is -7 2/3 + (-5 1/2) + 8 3/4
Veseljchak [2.6K]
Hey there :)

-7 \frac{2}{3} = - \frac{23}{3}
-5 \frac{1}{2} = -\frac{11}{2}
8 \frac{3}{4} = \frac{35}{4}

- \frac{23}{3} - \frac{11}{2} + \frac{35}{4}

We need to change all fractions to have a common denominator 

Lets see:
Multiples of 2: 2 , 4 , 6 , 8 , 10 , 12
Multiplies of 3: 3 , 6 , 9 , 12
Multiplies of 4: 4 , 8, 12

The common denominator is 12
2 x 6 = 12
3 x 4 = 12
4 x 3 = 12

= -\frac{23(4)}{3(4)} -  \frac{11(6)}{2(6)} +  \frac{35(3)}{4(3)}
= -  \frac{92}{12} -  \frac{66}{12} +  \frac{105}{12}

We need to add the numerators while keeping the same denominator
= - \frac{53}{12}
= -4 \frac{5}{12}
