Re-write the quadratic function below in Standard Form y = -(x – 3)2 +8

lisov135 [29]

Answer:

y = -x² + 6x - 1

General Formulas and Concepts:

Algebra I

Standard Form: ax² + bx + c = 0
Expanding by FOIL (First Inside Outside Last)
Combining like terms

Step-by-step explanation:

Step 1: Define equation

y = -(x - 3)² + 8

Step 2: Rewrite

Expand [FOIL]: y = -(x² - 6x + 9) + 8
Distribute -1: y = -x² + 6x - 9 + 8
Combine like terms: y = -x² + 6x - 1

The perimeter of a rectangular field is 168 feet. The field is 36 feet wide. How long is the field

Dmitriy789 [7]

To find the length, divide the peremiter by 2 and then subtract the width.

Length= Peremiter/2 - width
L = P/2 - W
L = 168/2 - 36
L = 84 - 36
L = 48

The length is 48

write a linear equation that has a slope of 1/2 and a y-intercept at the origin. (y=1/2x) (y=0x+1/2) (y=1/2x+1/2) (y=-1/2x)

Nesterboy [21]

Answer:

The linear equation with given slope and y-intercept is:

Option 1: $y = \frac{1}{2}x$

Step-by-step explanation:

The slope-intercept form of equation is given by:

$y = mx+b$

Here

m is the slope of the line and b is the y-intercept.

Given that

Slope of line is 1/2 so m = 1/2

And y-intercept is on origin so b = 0

Putting the values we get

$y = \frac{1}{2}x+0\\y = \frac{1}{2}x$

Hence,

The linear equation with given slope and y-intercept is:

Option 1: $y = \frac{1}{2}x$
