Answer:

$y=\frac{3}{2}x+8$

Step-by-step explanation:

The equation is in standard form already, which is typically mathematically expressed as, $Ax+By=C$ ; however, They want that equation to be expressed in slope-intercept form. This is commonly known as: $y=mx+b$ .

To get it in this form, we have to<em> </em>isolate y, meaning that we have to get it on one side of the equation, just like the slope-intercept form states.

So, let's do that! We know that -2y is 'By' from the standard form equation is needs to be by itself, so all we have to do is subtract 'Ax'; or in this case, 3x on both sides of the equation to get -2y by itself, leaving us one step closer to finishing the problem!

We now have the following equation: $-2y=-3x-16$

Remember, we have to get not just -2y by itself, we have to get y! We can do that by simply dividing both sides by -2 to get y by itself.

We now have the correct linear equation expressed in the slope-intercept form, which is: $y=\frac{3}{2}x+8$

Answer:this i going to took long time

Step-by-step explanation:Simplifying

3x + -2y = -16

Solving

3x + -2y = -16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

3x + -2y + 2y = -16 + 2y

Combine like terms: -2y + 2y = 0

3x + 0 = -16 + 2y

3x = -16 + 2y

Divide each side by '3'.

x = -5.333333333 + 0.6666666667y

Simplifying

x = -5.333333333 + 0.6666666667y

Which steps transform the graph of

vitfil [10]

Answer:

The correct option is the last one.

Step-by-step explanation:

To transform the graph of $y = x ^ 2$ into $y = -2(x - 2) ^ 2 + 2$ the following steps are fulfilled:

1) Move the graph 2 units to the right:

Let $y = f (x-2)$ then $y =(x-2) ^ 2$ Notice that the cut point has been moved to x = 2.

2) Reflect on the x axis:

To reflect a graph on the x-axis we do $y = -f(x)$ Then $f (x) = -(x-2) ^ 2$

3) Stretch according to factor 2.

For this we do $y = 2f(x)$

Then we have $f(x) = -2 (x-2) ^ 2$

4) Move up the graph in two units:

We do $y = f(x) +2$

Then $y = -2(x-2) ^ 2 +2.$

These steps coincide with those listed in the last option. Therefore the correct option is the last one.

"Translate 2 units on the right, reflect on the x-axis, stretch according to the factor 2 and translate 2 units"

Somebody answer !!!!!

Rainbow [258]

Answer:

Step-by-step explanation:

First we have to subtract 5 from both sides

$\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7$

Now, square both sides

$(\sqrt{x-6})^{2}=7^{2}$

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55

nikitadnepr [17]

Answer:

m=25w+80

Step-by-step explanation:

m=money

w=weeks

280-130=150

150/6=25 this is how much she earns per week

25*2=50 this is how much she earned in two weeks

130-50=80 this is how much she had before she worked

m=25w+80

plug in to check:

(25*2)+80=130

(25*8)+80=280
