Which of the following is an arithmetic sequence where a₁ = 9 and d= 7?

A) 9, 16, 23, 30, 37, ...
B) 0, 9, 18, 27, 36,...
C) 7, 16, 25, 34, 43,...
D) 0, 7, 14, 21, 28, ...

Answers

Answer 1

Answer:

Option A

Step-by-step explanation:

Arithmetic sequence:

  In a arithmetic sequence, difference between any two consecutive term is constant.

  a₁ = 9  & d = 7

         t₁ = 9

         t₂ = a₁ + d

             = 9 + 7

             = 16

         t₃ = t₂ + d = 16+ 7

            = 23

        t₄ = t₃ + d

            = 23 + 7

            = 30

        t₅ = t₄ + d

           = 30 + 7

           = 37

9,16,23,30,37,.......

A rectangle is covered by 24 unit squares. There are no gaps or overlap.

How can the area of the rectangle be found?


The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.

The area of the rectangle is half the number of unit squares that cover the rectangle. The area of the rectangle is 12 square units.

The area of the rectangle is double the number of unit squares that cover the rectangle. The area of the rectangle is 48 square units.

Answers

Answer: Choice A

The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.

=====================================================

Explanation:

Imagine drawing equally spaced grid lines to subdivide the rectangle. This splits the rectangle into smaller squares. In this case, each little square is 1 square unit. Having 24 of these squares leads to a total area of 24 square units.

We could have 8 rows and 3 columns of these squares to get 8*3 = 24 total. Or we could have 6 rows and 4 columns to get 6*4 = 24. Another configuration is 12 rows and 2 columns which leads to 12*2 = 24.

Describe the steps necessary to solve the following system equations:

-3x - 4y = 2 and 3x + 3y = -3

Answers

Answer:

(- 2, 1 )

Step-by-step explanation:

Given the 2 equations

- 3x - 4y = 2 → (1)

3x + 3y = - 3 → (2)

Adding the 2 equations term by term will eliminate the x- term, that is

0 - y = - 1

- y = - 1 ( multiply both sides by - 1 )

y = 1

Substitute y = 1 into either of the 2 equations and solve for x

Substituting into (2)

3x + 3(1) = - 3

3x + 3 = - 3 ( subtract 3 from both sides )

3x = - 6 ( divide both sides by 3 )

x = - 2

solution is (- 2, 1 )

Answer:

x = -2 and y = 1

Step-by-step explanation:

3x + 3y = -3, x + y = -1,  x = -y -1

-3(-y-1) - 4y = 2, 3y + 3 - 4y - 2 = 0

-y +1 = 0, y = 1

x + y = -1, x + 1 = -1, x = -2

Write the equation of the line in slope-intercept form that goes through the points (4, -2) and (8, -9)

Answers

Answer:

y = 17/6 x - 40/3

Step-by-step explanation:

Slope-intercept form: y = mx + b

First, let's find the slope:

slope formula: (y2-y1) divded by (x2-x1)

(4, -2) and (8, -9)

(-9 - 8) divded by (-2 - 4) = 17/6

We found m, now we have to find b.

The new equation: y = 17/6 x + b

Insert any of the two points, in this case, I'll insert (4, -2)

-2 = 17/6 (4) + b

-2 = 68/6 + b

b = -2 - 68/6

b = -40/3

Overall equation: y = 17/6 x - 40/3

y = -7/4 + 5

Steps are on paper.

Find the value of x
x°
66°
117°

Answers

Answer:

x = 51 degrees

Step-by-step explanation:

Keep in mind, the angles of a triangle add up to 180 degrees.

A flat line also equals 180 degrees.

First, we should find the lower left angle. We know that 117 plus that angle is going to be 180, since it's a flat line.

180 - 117 = 63

Now, we just need to find angle x. (All 3 of our angles should add up to 180, knowing this, we can put it in an equation)

63 + 66 + x = 180

Then, you solve for x:

(63+66) + x = 180

129       + x = 180

-129             -129

               x = 51

One pipe can fill a tank three times as fast as another pipe. If together the two pipes can fill the tank in 36 minutes, how many minutes would it take the slower pipe to fill the tank by itself? Your answer

Answers

Answer: 144 minutes

Step-by-step explanation:

Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.

Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.

Therefore,

1/x + 3/x = 1/36

4/x = 1/36

x = 36 × 4

x = 144

The number of minutes taken by the slower pipe will be 144 minutes.
