Answer: y = -2/3x in standard form is 2x + 3y = 0

Answer:

x + y = -2/3

Step-by-step explanation:

When changing something to standard form, you want all variables on one side, and the remaining numbers gone.

Answer:

There are 20 3-point questions and 8 5-point questions

Step-by-step explanation:

x=3 point y=5 point

x+y=28 ----> x=28-y

3x+5y=100

3(28-y)+5y=100

84-3y+5y=100

84+2y=100

2y=16

y=8

28-8=20

Answer:

20 3-point questions and

8   5-point questions.

Step-by-step explanation:

Let there be x 3 point problems and y 5 point problems. So we have:

x + y = 28              Multiply this equation by -3:

-3x - 3y = -84

3x + 5y = 100       Adding the last 2 equations:

0 + 2y = 16

y = 8

So x = 28 - 8 = 20.

Step-by-step explanation:

Answer:

x = 4.5, 4/7

Step-by-step explanation:

To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.

Answer:

51.3 packets or 51 1/3 packers

Step-by-step explanation:

From the above question:

The board he needs comes in packs of three. This means

1 pack = 3 boards

Hence:

3 boards = 1 packet

154 boards = x

Cross Multiply

3x = 154

x = 154/3

x = 51.333333333 packets

Approximately = 51.3 packets or 51 1/3 packers

The builder will need to buy 51.3 packets or 51 1/3 packers

Step-by-step explanation:

y-intercept in the point x = 0

B) is the easiest

g(x) or y value

g(x) = 3x² + 6x -9

= 3(0)² + 6(0) -9

= 0 + 0 -9

= -9

y-intercept = (0,-9)

Answer:

Step-by-step explanation:

A poodle puppy weighs 1.5 kg when it is born and gains 0.04 kg each day.

A golden retriever puppy weighs 1.2 kg when it is born and gains 0.1 kg each day.

How many days will it take for the two puppies to weigh the same amount

Answer:

90.5 cups

Step-by-step explanation:

Step one:

Given data

diameter= 24ft

radius= 12 ft

area= πr^2

Area= 3.142*12^2

Area= 3.142*144

Area= 452.448 ft^2

Hence if  

2 cups of fertilizer for every 10 square feet

x cups will do for  452.448 ft^2

cross multiply we have

x=  452.448 *2/10

x=904.896/10

x=90.5 cups

Answer:12/7

Step-by-step explanation:

The population decreases more quickly from day 1 to day 3 than from day 4 to day 6.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The total number of bacteria in lab dish is 1200

The population decreases 10% per day

In first day:

10/100×1200=120

120 bacteria decreased in lab

1200-120=1080

In second day:

0.1×1080=108

1080-108=972

In third day

0.1×972=97.2

972-97.2=874.8

In fourth day

0.1×874.8=87.48

874.8-87.48=787.32

In fifth day

0.1×787.32=78.732

787.32-78.732

708.588

The population decreases more quickly from day 1 to day 3 than from day 4 to day 6.

Hence, the population decreases  more quickly from day 1 to day 3 than from day 4 to day 6.

Answer: y-intercept: (0, 12)

Step-by-step explanation:

[tex]a_n[/tex] = 9 − 3 (n − 1)

Use the slope-intercept form to find the slope and y-intercept.

  The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

     y = mx + b

  Find the values of m and b using the form y = mx + b.

     m = −3

     b = 12

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

     Slope: −3

     intercept: (0, 12)

Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

  Find the x-intercept.

     To find the x-intercept(s), substitute in 0 for y and solve for x.

        0 = −3x + 12

      Solve the equation.

        Rewrite the equation as −3x + 12 = 0.

              −3x + 12 = 0

         Subtract 12 from both sides of the equation.

              −3x = −12

         Divide each term by −3 and simplify.

              x = 4

     x-intercept(s) in point form.

     x-intercept(s): (4, 0)

  Find the y-intercept.

     To find the y-intercept(s), substitute in 0 for x and solve for y.

        y = −3 ⋅ 0 + 12

   Solve the equation.

     Remove parentheses.

           y = −3 ⋅ 0 + 12

       Simplify −3 ⋅ 0 + 12.

           y = 12

     intercept(s) in point form.

     intercept(s): (0, 12)

  Create a table of the x and y values.

      x | y

     0 | 12

     4 | 0

Graph the line using the slope and the y-intercept, or the points.

Slope: −3

intercept: (0, 12)

Answer:

The slope of any line parallel to y=3x+4 would be 3!

Step-by-step explanation:
