Step-by-step explanation:

y=3(x-1)

multiply

3(x-1)

then y=3x-3

y+1=4/3(x+3)

multiply 4/3(x+3)

y=4/3x+3

Answer:

1) D. y = 3x-3

2) A. y = 4/3 x+3

Step-by-step explanation:

1)

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : y-(3*x-3)=0

Step 1:

Equation of a Straight Line

Solve   y-3x+3  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-3x+3  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000

 y-intercept = -3/1  = -3.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 1/1 Our line therefore "cuts" the x axis at x= 1.00000

 x-intercept = 3/3  =  1  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - (-3.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  6.000/2.000 =  3.000  

Geometric figure: Straight Line

 Slope = 6.000/2.000 = 3.000

 x-intercept = 3/3 = 1

 y-intercept = -3/1 = -3.00000

2)

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    y-(4/3*x+3)=0

Step 1:

Simplify   4/3

Equation at the end of step  1:

y -  ((4/3 • x) +  3)  = 0

Step 2: Rewriting the whole as an Equivalent Fraction

Adding a whole to a fraction

Rewrite the whole as a fraction using  3  as the denominator :

3 = 3/1 = 3 · 3/3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4x + 3 · 3/3 = 4x+9/3

Equation at the end of step  2:

y - (4x+9)/3=0

Step 3:

Rewriting the whole as an Equivalent Fraction :

Subtracting a fraction from a whole

Rewrite the whole as a fraction using  3  as the denominator :

y = y/1 = y · 3/3

Adding fractions that have a common denominator :

Adding up the two equivalent fractions

y • 3 - ((4x+9))     3y - 4x - 9

————————————————  =  ———————————

       3                  3      

Equation at the end of step

3

:

 3y - 4x - 9

 ———————————  = 0  

      3      

STEP

4

:

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 3y-4x-9

 ——————— • 3 = 0 • 3

    3    

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  3y-4x-9  = 0

Equation of a Straight Line

4.2     Solve   3y-4x-9  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  3y-4x-9  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 3/1 so this line "cuts" the y axis at y= 3.00000

 y-intercept = 9/3  =  3  

Calculate the X-Intercept :

When y = 0 the value of x is 9/-4 Our line therefore "cuts" the x axis at x=-2.25000

 x-intercept = 9/-4  = -2.25000  

Calculate the Slope :

    Slope     =  2.667/2.000 =  1.333  

Geometric figure: Straight Line

 Slope = 2.667/2.000 = 1.333

 x-intercept = 9/-4 = -2.25000

 y-intercept = 9/3 = 3

The value of the expression is 1

From the question,

We are to evaluate the value of the expression {[(20−32)÷(−6)]2−11}÷(−7)

To do this, we will clear the brackets one after the other.

The expression can be simplified as shown below:

{[(20−32)÷(−6)]2−11}÷(−7)

{[(-12)÷(−6)]2−11}÷(−7)

Then, we get

Answer:

y = -2x - 4

Step-by-step explanation:

First, I'll find the slope by subtracting the y-values and x-values of each point from each other, as shown below:

(-2 - (-4))/(-1 - 0) = 2/-1 = -2

We already have the y=intercept: (0, -4). From this, we can write a y = mx + b (slope intercept form) equation, with m being our slope and b being our y-intercept. It looks like y = -2x - 4.

Equation: y = -1x + 4

Step-by-step explanation:

In order to create an equation, you need to put it in slope-intercept form ( y = mx + b ). The best way to figure out to create your equation is to graph the points. 'Y' means the y-axis. 'mx' refers to the slope of a particular line and b is concluding where the line crosses the y-axis.

Step-by-step explanation: TOOK THE FOR K12 HOPE THIS HELPS

The difference of the given expression is 3/20 x - 3.

Given that, (2/5x−1)−(1/4x+2).

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, (2/5x−1)−(1/4x+2)

= (2/5 x - 1/4 x) -1 - 2

= (8/20 x - 5/20 x) - 3

= 3/20 x - 3

Therefore, the difference of the given expression is 3/20 x - 3.
