Explain how to write the equation of a line if you know its y-intercept and the equation of a line to which it is parallel? btw i need this answer asap (0_0)
THANK YOU PEOPLE OF THE WORLD

Answer 1
Answer: If you use the equation y = mx+b then you already know what the b term is because you have the y intercept. For the m (slope) you take the slope of the other line and use that because since there parallel they are going to run at the same angle (slope). Hope this helped. If you have any questions just ask.

Answers

A polynomial in standard form has terms arranged with the highest exponent on leftmost side and the lowest exponent on the right end. The variables are also arranged alphabetically.

Therefore, the exponent of the x-term must be 2 for the polynomial to be fully simplified and written in standard form.

5 times a number increasedby 18 is the same as 36 more
than times 4 times the
number. Find the number.

Answers

Answer:

18

Step-by-step explanation:

Let's make this information into an equation.

We'll use 'x' whenever the problem says "a number".

Equation:

5x + 18 = 36 + 4x

How did I get to this equation?

  • 5 times a number means 5 multiplied by x
  • increased by 18 means to add 18
  • is the same as means equals
  • 36 more than means to add 36
  • 4 times the number means 4 multiplied by x

Now, let's solve.

Solve:

5x + 18 = 36 + 4x

Subtract 18 on both sides:

5x + 18 = 36 + 4x

     -18     -18

5x = 18 + 4x

Subtract 4x on both sides:

5x = 18 + 4x

-4x        -4x

x = 18

Therefore, "the number" is 18.

How to solve and graph this equation ?

Answers

Start by adding 2y so that the equation becomes 2y= -3x-4 then divide by 2 on both sides so it cancelled out. (This if for if your trying to get it in y=mx+b form)

Answers

  by using calculator, these are the answers:
√20 = 4.47213595499958

√18 = 4.24264068711928

but without calculator,

√20 = √(4x5)
= √4 x √5
= 2 x √5
= 2√5

√18 = √(9x2)
= √9 x √2
= 3 x √2
= 3√2

Regina owns 150 shares of a company’s stock. When the stock market opened, each share traded for $23.65. When the stock market closes, Regina will calculate how much money she gained or lost from the stock that day. How much can Regina reasonably expect her stock to be worth? Write an equation for the problem and then use the equation to answer the question.

Answers

Regina expect 150*$23.65=$3547.5
The sum of Regina's expect is $3547.5

150*23.65=3547.5

$3,547.50
