Equation 1)  8x + 6y = 48
Equation 2)  2x - 3y = -6

Multiply all of equation 2 by 2.

2)  2(2x - 3y = -6)

Simplify.

2)  4x - 6y = -12
1)  8x + 6y = 48

Add equation together.

12x = 36

Divide both sides by 12.

x = 3

Plug in 3 for x in the first equation.

8x + 6y = 48

8(3) + 6y = 48

Simplify.

24 + 6y = 48

Subtract 24 from both sides.

6y = 48 - 24

Simplify.

6y = 24

Divide both sides by 6.

y = 24/6

y = 4

So, x = 3, y = 4

Graph the line with slope 1/2 passing through the point (5, - 1)
True [87]

Answer:

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

Step-by-step explanation:

We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.

We're given the slope, (1/2) which we can use for m:

y = (1/2)x + b

We are told the line goes through (5,-1).  We need a value of b that will move the line to include this point.  Do that by substituting the values:

 x = 5, and y= -1

y = (1/2)x + b

-1 = (1/2)*5 + b

-1 = (2.5) + b

- 3.5 =   b

<u><em>The equation is y = (1/2)x + - 3.5</em></u>

See the attached image.

Riley rides his bicycle 1.8 km to Jillian’s house. On the way back, he takes a route that is 740 m shorter than the first route.
postnew [5]
1.8 km >> 1,800 m
1,800 - 740 = 1,060 m
1,060 m >> 1.06 km
The shorter route is 1.06 km.
