Slope: 4

Y-interecept: -2

Step-by-step explanation:

To find the slope, use rise over run. Go up from the y-intercept and over until you hit another exact point.

To find the y-intercept, just find the point that is on the y-axis.

y intercept is -2 and the slope is 3

An arithmetic sequence is represented by the explicit formula A(n) = 8 - 6(n - 1) What is the recursive formula? Group of answer choices

Answers

Answer:

A(1) = -4A(n) = A(n - 1) - 6

Step-by-step explanation:

GivenAP with the explicit formula A(n) = 8 - 6(n - 1)To find Recursive formulaSolution

Recursive formula is the formula A(n) = A(n - 1) + d

Based on the explicit formula we have:

A(n) = 8 - 6(n - 1) = 8 - 6n + 6 = 2 - 6nA(n - 1) = 2 - 6( n - 1) = 2 - 6n + 6 = 8 - 6n

The common difference is:

d  = A(n) - A(n - 1) = 2 - 6n - (8 - 6n) = 2 - 6n - 8 + 6n = - 6

The first term is:

A(1) = 2 - 6(1) = 2 - 6 = -4

So the recursive formula is:

A(1) = -4A(n) = A(n - 1) - 6

Use the graph to write a linear function that relates y to x .

Answers

Answer:

2y = x + 2

Step-by-step explanation:

Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;

From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:

[tex]m = \frac{dy}{dx} = \frac{1}{2}[/tex]

Joining the points gives a straight line, which means a constant gradient of ¹/₂

Use the line equation formula to get the function:

y - y₁ = m(x - x₁)

m = ¹/₂

x₁ = 0

y₁ = 1

y - 1 = ¹/₂.(x - 0)

y - 1 = ¹/₂.x

2y - 2 = x

2y = x + 2

Flying against the wind, a jet travels 2480 miles in 4 hours. Flying with the wind, the same jet travels 7040 miles in 8 hours. What is the rate of the jet in still air and what is the rate of the wind?

Answers

Answer:

The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.

Step-by-step explanation:

Given that:

Distance traveled by jet against the wind = 2480 miles in 4 hours

Combined speed = [tex]\frac{Distance}{Time}[/tex] = [tex]\frac{2480}{4}[/tex]

Combined speed = 620 miles per hour

Distance traveled with wind = 7040 miles in 8 hours

Combined speed = [tex]\frac{7040}{8}[/tex]

Combined speed = 880

Let,

Speed of jet = x

Speed of wind = y

When jet travels against the wind, the speed will be subtracted

x-y=620      Eqn 1

When jet travels with the wind, the speed will be added

x+y=880     Eqn 2

Adding Eqn 1 and 2

(x-y)+(x+y)=620+880

x-y+x+y=1500

2x=1500

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{1500}{2}\\x=750[/tex]

Putting x=750 in Eqn 2

750+y=880

y=880-750

y=130

Hence,

The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.

regularly, you would +20 to both sides, but without a full =, you cant solve. If the equation is 6x-20=0, x would equal 3 2/6.

Hope this helps!

ok so you have 6x-20 it would be in the negatives so when you do that it stays negative because one negative stays as negative so you subtract -20 first then you multiply that by 6x which would give you negative 120 (-120
