Answer:

y = 5

Step-by-step explanation:

Get y by itself:

3y - 2 = 13

     +2    +2

3y = 15

Divide by 3:

3y = 13

÷ 3    ÷ 3

y = 5

Answer:

y = 5

Step-by-step explanation:

3y - 2 = 13

We are solving for y, so we want to isolate it.

Add 2 to both sides.

3y = 15

Continue isolating y by dividing both sides by 3.

y = 5

Check your answer by plugging it back into the original equation.

3y - 2 = 13

3(5) - 2 = 13

Multiply.

15 - 2 = 13

Subtract.

13 = 13

Your answer is correct.

Hope this helps!

Your favorite stock opened the day's trading at $44.17 per share. When trading closed for the day, your stock was priced at $38.
Masja [62]

Answer:

$835.20

Step-by-step explanation:

First you need to find out how many profit you had at first by multiplying 145 and $44.17.

So, 145*$44.17 = 6404.65

Then find out how much profit you had after it decreased by multiplying 145 and $38.41.

So, 145*$38.41 = 5569.45

Now to find how much profit you lost, you have to subtract $6,404.65 and $5,569.45.

$6,404.65 - $5,569.45 = $835.20

What is the slope of the line that passes through the points (6,0) and (21,-20)
Paha777 [63]

Answer:

\Longrightarrow: \boxed{\sf{-\dfrac{4}{3} }}

Step-by-step explanation:

<u>To find:</u>

  • The slope of the line that passes through the points.

<u>Note:</u>

  • Use the slope formula.

\underline{\text{SLOPE FORMULA:}}

\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{RISE}{RUN}  }

  • y₂=(-20)
  • y₁=0
  • x₂=21
  • x₁=6

\Longrightarrow: \sf{\dfrac{(-20)-0}{21-6}}

<u>Solve.</u>

\sf{\dfrac{-20-0}{21-6}=\dfrac{-20}{15}=\dfrac{-20\div5}{15\div5}=\dfrac{-4}{3}=\boxed{\sf{-\dfrac{4}{3}}}

  • <u>Therefore, the slope is -4/3, which is our answer.</u>

I hope this helps. Let me know if you have any questions.

What is the vertex form of y=-1/2x^2 -2x -3?
STALIN [3.7K]

Answer:

y = − 1 2 ⋅ ( x + 2 ) 2 − 1

Step-by-step explanation:

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.

Very glad I could help you!1
