Determine Which Of The Lines, If Any, Are Parallel. Explain.Line A Passes Through (-1, - 2) And (1,0).Line

Answers

Answer 1

Answer:

Line A and Line C are parallel

Step-by-step explanation:

Slope Equation: [tex]m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Step 1:  Find the slope of the first line

Line a passes through (-1, -2) and (1, 0).

[tex]m = \frac{(0- (-2))}{(1 - (-1))}[/tex]

[tex]m=\frac{2}{2}[/tex]

[tex]m=1[/tex]

Step 2:  Find the slope of the second line

Line b passes through (4, 2) and (2, -2).

[tex]m = \frac{(-2- 2)}{(2 - 4)}[/tex]

[tex]m = \frac{-4}{-2}[/tex]

[tex]m=2[/tex]

Step 3:  Find the slope of the third line.

Line c passes through (0, 2) and (-1, 1).

[tex]m=\frac{(1-2)}{(-1 - 0)}[/tex]

[tex]m=\frac{-1}{-1}[/tex]

[tex]m=1[/tex]

Answer:  Line A and Line C are parallel

need help i dont know what I am doing

Answers

Answer:

answer below:)

Step-by-step explanation:

Basically, start off by simplifying each pair of numbers.

The first one: [tex]2^{2}[/tex] x 5 = 4 x 5 = 20

The second one: [tex]11^{1}[/tex]= 11

The third: [tex]8^{2}[/tex]-60 = 64 - 60 = 4

Now from least to greatest, so that would be 4, 11, 20 or in this case it would then be [tex]8^{2}[/tex]-60,  [tex]11^{1}[/tex],  [tex]2^{2}[/tex] x 5

The sum of two numbers is 38. The larger number is 8 more than the smaller number, What are the numbers?
Larger number:
Smaller number.

Answers

Answer:

Larger number: 23

Smaller number. 15

Step-by-step explanation:

y = x - 8

x + y = 38

substitute for y:

x + x - 8 = 38

2x = 46

x = 23

y = 15

Answer:   Larger number:  23

Smaller number:  15

Step-by-step explanation:

let x be the smaller number, then the larger number would be x+8

x + (x + 8) = 38

2x + 8 = 38

2x  = 30

x = 15

larger number = x + 8 = 15 + 8 = 23

Determine the number of liters of a 30% saline solution and the number of liters of a 60% saline solution that are required to make 10 liters of a 50% saline solution.

Answers

Answer:

Number of liters of 30% solution = x = 3.3 liters

Number of liters of 60% solution = y

= 6.67 liters

Step-by-step explanation:

Let us represent:

Number of liters of 30% solution = x

Number of liters of 60% solution = y

Determine the number of liters of a 30% saline solution and the number of liters of a 60% saline solution that are required to make 10 liters of a 50% saline solution.

30% × x + 60% × y = 10 × 50%

0.3x + 0.6y = 5...... Equation 1

x + y = 10...... Equation 2

x = 10 - y

We substitute 10 - y for x in Equation 1

Hence

0.3(10 - y) + 0.6y = 5

3 - 0.3y + 0.6y = 5

- 0.3y + 0.6y = 5 - 3

0.3y = 2

y = 2/0.3

y = 6.67 liters

Solving for x

x = 10 - y

x = 10 - 6.67

x = 3.33 liters

Hence:

Number of liters of 30% solution = x = 3.3 liters

Number of liters of 60% solution = y

= 6.67 liters
