2x + 3y = 6

Put this into y=mx+b form (which is also called slope-intercept form)

Where m=slope and b=y-intercept

In order to put this into slope-intercept form, we simply need to subtract 2x from both side.s

3y = 6 - 2x

Then, divide both sides by 3 so that we fully isolate y.

3y ÷ 3 = (6 - 2x) ÷ 3

Simplify.

y = 2 - 2/3x

Put this into order by moving "x" onto the correct place.

y = -2/3x + 2

Therefore -2/3 is the slope, as it is in the "m" spot.

Hope I helped! :)

For slope, the equation is y = mx + b, and so you must reorder them to fit the equation

first move the x over

2x (-2x) + 3y = 6 (-2x)

your equation will look like this now:

3y = -2x + 6

as the form is y = mx + b, you must isolate the y by dividing the 3 to both sides.

3y/3 = (-2x + 6)/3

y = -2x/3 + 2

your equation is

y = -2/3x + 2

your slope is m, which is -2/3 in this case

your answer is -2/3

hope this helps

What is the letter a? 6a+14=-7-a. a=?
grin007 [14]

<span>6a+14=-7-a

you simplify the equation to the form, which is simple to understand
<span>6a+14=-7-a

you move all terms containing a to the left and all other terms to the right.
<span>+6a+1a=-7-14

you need to simplify left and right side of the equation.
<span>+7a=-21

you divide both sides of the equation by 7 to get a.

Company B: starting salary-28,000 Yearly salary increase-2,400
Naya [18.7K]

Answer:

Sharla, 4400

Step-by-step explanation:

Paul's Salary:

Paul started at company B. Starting salary of company B is $ 28,000 with a yearly increase of $ 2,400. Paul's Salary in first year will be 28,000. In second year his salary will be 28000 + 2400, in 3rd year his salary will be: 28000 + 2(2400) and so on.

Since, the increase in Paul's salary every year is $ 2400, the increase in his salary after 10 years or in 10th year would be = 2400 x 9 = $ 21,600

So, his total salary in 10th year would be = 28000 + 21600 = $ 49,600

Sharla's Salary:

Sharla started at company C. Starting salary of company C is $ 36,000 with a yearly increase of $ 2,000.

Since, the increase in Sharla's salary every year is $ 2000, the increase in her salary after 10 years or in 10th year would be = 2000 x 9 = $ 18,000

So, her total salary in 10th year would be = 36000 + 18000 = $ 54,000

Conclusion:

Sharla earned more in 10th year an amount equal to $ 4400. So the answer is:

In the last year, <u>Sharla</u> earned <u>$4,400</u> more.

If you know the 7x8=56 how can you use the Commutative Property of Multiplication to find the product of 8x7?
boyakko [2]

Answer:

The communicative property for multiplication states that the order of the multiplicands and can be swapped and the resulting product stays the same.

So

A * B = B * A

So if

7*8=56

then the commutative property says

8*7=56 as well since you can swap the order of the terms on the left and not change the result.

This property is true for addition and multiplication. It does not hold for subtraction or division.

Hope that makes sense and helps. (:
