Answer:x + 2y = 6

2y = -x + 6

 y = -1/2 x + 3 so slope = -1/2

parallel lines  has same slope = -1/2

perpendicular lines slope is opposite and reciprocal so slope = 2  

if slope not equal either -1/2 or 2 then neither.

y = -1/2 x - 5 ....m= - 1/2....  parallel

-2x + y = -4

         y = 2x - 4...m = 2 ....perpendicular

-x + 2y = 2

2y = x + 2

y = 1/2 x + 1 ...m = 1/2 ...neither

x + 2y = -2

2y = -x - 2

 y = -1/2 x - 1 ...m = -1/2 .....parallel

One soda and one taco costs $2.1. Two sodas and three tacos cost $5.15. Find the cost of a soda and a taco. Whoever answer this
DaniilM [7]

Answer:

Soda costs $1.15 and taco costs $0.95.

Step-by-step explanation:

x + y = 2.1

2x + 3y = 5.15

Multiply the first equation by -2 to eliminate x

-2x - 2y = -4.2

2x + 3y = 5.15

Add

          y = 0.95

Find x with the original first equation

x + y = 2.1

x + 0.95 = 2.1

x = 2.1 - 0.95

x = 1.15

hope it helps :)

- 3x + 9 - 4 = x + 3 + 2x​
Gwar [14]
-3x + 9 - 4 = x + 3 + 2x
-3x + 9 - 4 = 3x + 3
9 - 4 = 6x + 3
5 = 6x + 3
2 = 6x

Juliette [100K]

Answer:

1. Use a compass to make arc marks which intersect above and below then connect.

2. y=\frac{1}{3}x + 2

Step-by-step explanation:

1. To construct a perpendicular line, use a compass to draw arc marks from one end of the segment through point P. Then repeat this again at the other end. This means at point P there will be two intersecting arc marks. Repeat the process down below with the same radius as used above. Then connect the two intersections.

2. The point slope form of a line is (y-y_1)=m(x-x_1) where x_1=-3\\y_1=1. We write  

(y-1)=m(x--3)\\(y-1)=m(x+3)  

Since the line is to be perpendicular to the line shown it will have the negative reciprocal to the slope of the function 3x+y =-8. To find m, rearrange the function to be y=-8-3x. The slope is -3 and the negative reciprocal will be 1/3.

(y-1)=\frac{1}{3}(x+3)  

Simplify for slope intercept form.

(y-1)=\frac{1}{3}(x+3)\\(y-1)=\frac{1}{3}x+1\\y=\frac{1}{3}x + 2
