What is the solution to the system of equations graphed below?

y = 4x + 11

y = -2x - 1

Answers

Answer 1

Answer:

Step-by-step explanation:

y = 4x + 11, and y = -2x - 1, so

4x + 11 = -2x - 1

6x + 11  = -1

6x = -12

x = -2

y = 4x+11 = 3

Answer 2

y = 4x + 11

y = -2x - 1

4x + 11 = -2x - 1

4x + 2x = -1 - 11

6x = -12

x = -12/6

x = -2

y = 4x + 11

y = 4(-2) + 11

y = -8 + 11

y=3

Answer is (-2,3).

The series C: 625 – 125 + 25 – 5 + …   converges. Explanation given.

What is common ratio?

The distance between each number in a geometric series is known as the common ratio. The ratio between two consecutive numbers, or a number divided by the number before it in the sequence, is known as the common ratio since it is the same for all numbers or common.

Given series:

A: 9 + 81 + 729 + …

B: 1 + 0.25 + 0.0625 + 0.015625 + …

C: 625 – 125 + 25 – 5 + …

D: 8 – 16 + 32 – 64 + …

To prove convergence:

A: 9 + 81 + 729 + …

Simplifying,

9 + (9)² + (9)³+ ....

The first term = 9

The second term = (9)²

So, the ratio = 9

That means, the geometric series with common ratio

IrI = 9 > 1

So, if the common ratio of geometric series is greater than 1 then the series diverges.

B: 1 + 0.25 + 0.0625 + 0.015625 + …

Simplifying,

1 + (1/4) + 1/(4)²+ ....

The first term = 1

Second term = 0.25

Third term = 0.0625

The ratio r = 4

IrI = 4 > 1

So, if the common ratio of geometric series is greater than 1 then the series diverges.

C: 625 – 125 + 25 – 5 + …

Simplifying,

The first term = 625

Second term = 125

Third term = 25

The ratio r = -125/625 = -1/5

IrI = 1/5 < 1

So, if the common ratio of the series is lesser than 1 then the series converges.

D: 8 – 16 + 32 – 64 + …

The first term = 8

Second term = -16

The ratio = -16/8 = -2

IrI = 2> 1

So, if the common ratio of the series is greater than 1 then the series diverges.

Therefore, the series C converges.

The weight of a puppy is 1.6 kg and the weight of a kitten is 750 g. What is the difference in their weights (measured in g)?

Answers

You would multiply 1.6kg by 1000 to get the amount of grams since 1000 grams equals one kilogram.

So 1.6x1000=1600

Then you would take 1600 and subtract 750 from it to get the difference which is 850g! Hope this helped :^)

Answer:

850g difference

Step-by-step explanation:

1 kilograms is equal to 1000 grams and every 0.1 kilogram is 100, so 1.6 kilograms into grams is 1600 grams. 1600-750=850

Answer:

x = 11

Step-by-step explanation:

interior angles of a triangle = 180

equation:

⇒ 82 + 31 + 6x + 1 = 180

combine like terms:

⇒ 82 + 31 + 6x + 1 = 180

⇒ 114 + 6x = 180

subtract 114 on both sides:

⇒ 114 - 114 + 6x = 180 - 114

⇒ 6x = 66

divide 6 on both sides:

⇒ 6x = 66

⇒ [tex]\frac{6x}{6} = \frac{66}{6}[/tex]

⇒ x = 11
