What is y=X2-6x+7 in vertex form
alina1380 [7]

Answer:

y = (x - 3^{2}) - 2

Step-by-step explanation:

y = a (x - h)^{2} + k

Standard form: y = ax^{2} + bx = c

Our vertex is: xvertex = - \frac{b}{2a} \\y = x^{2} - 6x + 7 ( STANDARD -  FORM)\\

Finally we get y = (x - 3^{2}) - 2 as our answer.

Have an amazing day!

Jack will spend a total of exactly $15 on Redbix movies and games. What equation in standard form can he use to graoh a line sho
alina1380 [7]

Answer:

1.25x+2.5y -15 = 0

Step-by-step explanation:

Total amount to be spent on Redbix movies and games = $15

Money to be paid for each movie = $1.25

Money to be paid for each game = $2.50

To find:

Equation in standard form that can be used to graph the line.

Solution:

First of all, let us learn about the standard form of equation of a line.

Standard form can be represented as:

Ax+By+C =0

Where A,B, C are constants.

Now, let us try to make equation.

Let number of movies bought = x

Amount to be paid for movies = $1.25x

Let number of movies bought = y

Amount to be paid for movies = $2.50y

Total money is $15.

Therefore, we can write the equation as:

1.25x+2.5y = 15

Standard form can be written as:

1.25x+2.5y -15 = 0
