Answer:

The standard form of y = 3 x + 1 is         -3x + y = 1 .

The standard form of y  = 4x - 7 is         -4x + y = -7.

Step-by-step explanation:

Here the given equation are:

y = 3 x + 1

and y  = 4x - 7

The above equations are of the form:  y = m x + C

Now, the STANDARD FORM of the equation is Ax + By  = C

<u>Consider equation 1: </u>

y = 3 x + 1

or, y - 3x  = 1

or. -3x + y = 1

⇒ The equation  -3x + y = 1  is in STANDARD FORM.

<u>Consider equation 2: </u>

y = 4 x - 7

or, y - 4x  = -7

or. -4x + y = -7

⇒ The equation -4x + y = -7 is in STANDARD FORM.

Pavel [41]

Answer:

The answer to your question is x₁ = 10; x₂ = 5i; x₃ = -5i

Step-by-step explanation:

                                            x³ - 10x² + 25x - 250 = 0

Factor by grouping

                                     x²(x - 10) + 25(x - 10) = 0

                                   (x - 10) (x² + 25) = 0

                                     x₁ - 10 = 0

                                    x₁ = 10

                                     x² + 25 = 0

                                    x² = -25

                                    x² = ± √-25

                                    x² = ± √25i²

                                    x₂ = 5i

                                    x₃ = -5i

Ethan buys a video game on sale. If the video game usually costs $39.99, and it was on sale for 20% off, how much did Ethan pay.
Firlakuza [10]

Answer: $31.99


Step-by-step explanation:

So, it is originally $39.99, so first we convert 20% to a decimal, which is 0.2.

Then we do 39.99 * 0.2 to find how much money was taken off.

39.99 * 0.2 = 7.998, or $8

Now, we do the original dollar amount, $39.99, minus the discount, $8, which equals $31.99.
