-2 (m+3) - 5m = -34
Help please

-2 (m+3) - 5m = -34Help Please

Answers

Answer 1

Answer:

m = 4

Step-by-step explanation:

Given

- 2(m + 3) - 5m = - 34 ← distribute and simplify left side

- 2m - 6 - 5m = - 34

- 7m - 6 = - 34 ( add 6 to both sides )

- 7m = - 28 ( divide both sides by - 7 )

m = 4

What is the slope of a line parallel to the line whose equation is y=3x + 4?​

Answers

Answer:

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

Step-by-step explanation:

When lines are parallel, they always have the same slope!

When lines are perpendicular, the slope would be the negative reciprocal!

10. The test was worth 100 points. There were 28 problems on the test. Some of the
problems were worth 3 points and others were worth 5 points. How many of each were
there?

Answers

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.

There are 1,200 bacteria in a lab dish. The population decreases 10% per day. Compare the decrease in the population for days 1 to 3 with the decrease for days 4 to 6.

Complete the sentence with “more quickly,” “less quickly,” or “at
the same rate.”

The population decreases [ Select ] from day 1 to day 3 than from day 4 to day 6.

Answers

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

What is Percentage?

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.

Step-by-step explanation:

Rewrite the explicit formula in function form. The identify the y
intercept of the function.
an = 9-3(n-1)

Answers

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)

A builder needed to buy one hundred fifty-four boards for his latest project. If the board he needs comes in packs of three, how many packets will he need to buy

Answers

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
