The answer is (3,4)  b/c

Work :

x= 3(8-y)/4

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

Answer:

y=6x+4

Step-by-step explanation:

now the formula for slope-intercept is y=mx+b

Slope (aka m) is 6

[how I got the slope is every time it goes forward 1 it goes up 6  rise/run]

so y=6x+[y intercept]

the y intercept is 4 as seen in the chart so:

y=6x+4

enjoy^^

$7.80/hour = ____ cents/minute? a. 4.7 b. 13 c. 8.8 d. 780
g100num [7]
1$ = 100 cents,    1 hour = 60 minutes

$7.80/hour =  (7.8*100) cents / (1*60)minutes
 
                   =  780 cents/60 minutes
 
                   = 13 cents/minute

Compare Look at these equations. Do you think they are all linear equations? Can they
Georgia [21]

Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

What is the slope of a line with endpoints at (3,4) and (2,5)?
Lesechka [4]

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-4}{2-3}\implies \cfrac{1}{-1}\implies -1
