Answer:

3x + y = -5

General Formulas and Concepts:

Pre-Algebra

Distributive Property
Equality Properties

Algebra I

Standard Form: Ax + By = C

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

[PS] y - 11 = 3(x - 2)

Step 2: Rewrite

Find Standard Form

Distribute 3: y - 11 = 3x - 6
Subtract 3x on both sides: -3x - y - 11 = -6
Add 11 to both sides: -3x - y = 5
Factor -1: -1(3x + y) = 5
Divide -1 on both sides: 3x + y = -5

The area of this square

ANEK [815]

It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.

The area of a square is given by the equation $A=s^{2}$ where s is the length of the side.

$A=24^{2}$

A=576

The area of this square is 576cm2.

Hope this helps!

The square below represents one whole.

grandymaker [24]

Answer:

Fraction: 81/100

Decimal: 0.81

Percentage: 81%

Step-by-step explanation:

The question is complete but the diagram mentioned can be found in

brainly.com/question/12188410

First step is to find the area of the whole square and then the area of the part that was shaded.

From the diagram, there are 100 squares in the whole square. 81 of those squares are shaded.

Area of the whole square = 10 by 10

= 10×10 = 100unit²

Area of shaded region = (10 by 8) + 1

= 80+1 = 81unit²

shaded area expressed as a fraction = 81unit²/100unit²

= 81/100

Shaded area expressed as a decimal = 81/100

You take the number 81 and carry the point by two decimal place from the right

= 0.81

Shaded area expressed as a percent of the whole = (81/100) × 100

= (81×100)/100

= 81%

A x + b y is equal to 12

Nikitich [7]

Answer:

y= -a*x + 12

b b

Step-by-step explanation:

ax+by=12 (subtract "ax" from both sides so that the one on the left will become zero and we will have "by" )

by= -ax+12(divide both side by "by" so that we will have the equation as "y=mx+b")

finally the result will be:

y= -a*x + 12
