Answer:

1)y=2x-1: Neither

2)y=-2+5: Parallel

3)y=12x+7: Perpendicular

Step-by-step explanation:

I went on Desmos.com and graphed all of the equations. 1) crosses the equation but is not perpendicular because it doesnt form a 90 degree angle. 2) is obvious when you look at the graph and lastly 3) is the only one left and when it crosses it makes a 90 degree angle. Hope this helps <3

Y = -2x + 5 is parallel to line as the slopes ( = -2) are the same.

the other 2 lines are nether parallel or perpendicular

Fofino [41]

<u>The value of the expression is -35.</u>

<u>Step-by-step explanation:</u>

<u>Consider the provided expression.</u>

<u>3x + y </u>

<u>We need to find the value of the expression for x=13 and y=−74 .</u>

<u>Substitute the value of x=13 and y=−74 in the above expression as shown:</u>

<u>3 (13) + (-74)</u>

<u>39 - 74 </u>

<u>-35</u>

<u> the value of the expression is -35.</u>

17x-3y=4 2x-4y=1 the solution to the system of equations is

Burka [1]

ANSWER

$x=\frac{13}{62}$

and

$y= \frac{-9}{62}$ e have

EXPLANATION

$17x-3y=4---(1)$

$2x-4y=1$

Let us make y the subject and call it equation (2)

$2x=1+4y$

$x=\frac{1}{2}+2y--(2)$

We put equation (2) in to equation (1)

$17(\frac{1}{2}+2y)-3y=4$

$\frac{17}{2}+34y-3y=4$

$34y-3y=4- \frac{17}{2}$

Simplify to get,

$31y= \frac{8-17}{2}$

$31y= \frac{-9}{2}$

Divide both sides by 31,

$y= \frac{-9}{2} \div 31$

$y= \frac{-9}{2} \times \frac{1}{31}$

$y= \frac{-9}{62}$

We put this value in to equation (2) to get,

$x=\frac{1}{2}+2\times -\frac{9}{62}$

$x=\frac{1}{2} -\frac{18}{62}$

We collect LCM to obtain,

$x=\frac{31-18}{62}$

$x=\frac{13}{62}$
