Which equation represents a line which is parallel to the line 3x + 8y = - 40 ?

Answers

Step-by-step explanation:

3x + 8y = -40

8y = -40 - 3x

y = -5 - 3/8x

y = -3/8x - 5

Equation that represents a line which is parallel to y = -3/8x - 5 can be any equation as long as it's y = -3/8x + c, as in c can be any value as long as the other parts of the equation is not changed

Enter the value of the answer in the first blank and enter the units in the second.


Enter your answer in decimal form. Round to the nearest tenth if rounding is necessary.


Enter units as ft., square ft., or cubic ft.

Answers

Answer:

The area of each section of the kennel is 33 square ft

Step-by-step explanation:

The given parameters for the fencing are;

The length of each section, L = 2 ft + The width, 3×W

The total amount of fencing = 113 feet

The The total perimeter of the kennel = 12·W + 7·L = 113

Were we are given L = 2 + 3·W

By substitution, we have;

12 × W + 7 × (2 + 3·W) = 113

33·W + 14 = 113

33·W  = 113 - 14 = 99

W = 99/33 = 3

W = 3 ft.

L = 2 + 3·W = 2 + 3 × 3 = 11

L = 11 ft.

The area of each section of the kennel, A = L × W = 3 × 11 = 33 square ft.

The area of each section of the kennel = 33 square ft.

Line 1 and Line 2: Parallel O Perpendicular O Neither Х Line 1 and Line 3: O Parallel O Perpendicular O Neither Line 2 and Line 3: Parallel O Perpendicular Neither​

Answers

Answer:

Step-by-step explanation:

We will use the following steps to solve this problem,

Step - (1).

Covert the equations into slope-intercept form.

Step - (2)

If the slopes of the two lines are equal, lines will be parallel.

[tex]m_1=m_2[/tex]

Step - (3)

If the slopes of the two lines are negative reciprocal, lines will be perpendicular.

[tex]m_1\times m_2=-1[/tex]

Line 1: 8x - 6y = -2

          6y = 8x +2

            y = [tex]\frac{4}{3}x+\frac{1}{3}[/tex]

Slope of line 1 = [tex]m_1=\frac{4}{3}[/tex]

Line 2: y = [tex]-\frac{3}{4}x-5[/tex]

Slope of line 2 = [tex]m_2=-\frac{3}{4}[/tex]

Line 3: 4y = -3x + 3

             y = [tex]-\frac{3}{4}x+\frac{3}{4}[/tex]

Slope of line 3 = [tex]m_3=-\frac{3}{4}[/tex]

1). Since, [tex]m_1\times m_2=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

2). Since, [tex]m_1\times m_3=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

3). Since, [tex]m_2=m_3=-\frac{3}{4}[/tex]

   Line 2 and line 3 are parallel.

3) The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take? I got 92 am I correct to crazy? 100 minutes 95 minutes 90 minutes 80 minutes

Answers

Given:

The International Space Station takes 644 minutes to orbit Earth 7 times.

To find:

The time taken by each orbit.

Solution:

Total time = 644 minutes

Total number of orbits =7

Now,

[tex]\text{Time taken be each orbit}=\dfrac{\text{Total time}}{\text{Number of orbits}}[/tex]

[tex]\text{Time taken be each orbit}=\dfrac{644}{7}[/tex]

[tex]\text{Time taken be each orbit}=92[/tex]

So, the required time is 92 minutes.

Therefore, you are correct and all options are incorrect.

Which point lies on the graph of the finite sequence shown? 5,-1,6, 0, 7, 1,8 O (-1,2) (0,5) (5, 1) (6, 1) ​

Given that;

A sequence is,

⇒ 5, -1, 6, 0, 7, 1, 8

Now, You have to look at the first coordinate (x -Axis) then go over that many times in the sequence and if that number is matched with the y-axis, then you got it.

Hence, Look at your numbers then go to (6, 1) go over 6 and if you land on 1 then that's the answer.
