You are kayaking along a 24-mile stretch of river. You travel 6 miles per hour when paddling and 2 miles per hour when drifting. Give three possible combinations of paddling and drifting times. Write your answers as ordered pairs.

Answers

Answer:

(1,6), (2,6), (3,3)

Step-by-step explanation:

Since you travel 6 miles per hour when paddling and 2 miles per hour when drifting, and the total distance covered is 24 miles, we find the times t and t' of paddling and drifting respectively in which the product 6t + 2t' = 24.

So, for the first values of t and t' , we have t = 1 and t' = 9

So, 6t + 2t' = 6 × 1 + 2 × 9 = 6 + 18 = 24

As an ordered pair (1, 9)

For the second set of values of t and t' , we have t = 2 and t' = 6

So, 6t + 2t' = 6 × 2 + 2 × 6 = 12 + 12 = 24

As an ordered pair (2, 6)

For the third set of values of t and t' , we have t = 3 and t' = 3

So, 6t + 2t' = 6 × 3 + 2 × 3 = 18 + 6 = 24

As an ordered pair (3, 3)

So, the three different combinations of paddling and drifting times are (1,6), (2,6), and (3,3)

Answers

Answer:

do distributive property on both, so multiply 6•x and 6•-4. then multiply 7•x and 7•3.

so it'll basically be 6x - 24 = 7x + 21.

then add 24 to both sides so: 6x - 24 + 24 = 7x + 21 + 24. since -24+24=0 it'll be 6x = 7x + 21 + 24.

then add 21 + 24 and that will be 45.

so 6x = 7x + 45

then subtract 7x from both sides 6x - 7x = 7x + 45 - 7x

that'll be -x = 7x + 45 - 7x

combine like terms (7x - 7x) = 0

so -x = 45

and since x can't be negative, do the opposite signs

so instead of -x = 45, make it x = -45

what is the effect on the graph of the function f(x)=x^2 when f(x) is changed to f(x)+9

Answers

Given:

The function is

[tex]f(x)=x^2[/tex]

This function is changed to f(x)+9.

To find:

The effect on the graph of the function.

Solution:

The translation is defined as

[tex]g(x)=f(x)+b[/tex] .... (1)

Where, b is vertical shift. If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The new function is

[tex]g(x)=f(x)+9[/tex] ...(2)

From (1) and (2), we get

[tex]b=9[/tex]

So, the graph of f(x) shifts 9 units up as shown in the below graph.
