On a coordinate grid, what is the distance from A (4,9) to B (4,3)?

Answers

$d=√((x_1-x_2)^2+(y_1-y_2)^2)\n\nd=√((4-4)^2+(9-3)^2)\nd=√(0^2+6^2)\nd=√(6^2)\nd=6$

just subtract them
4-4=0
9-3=6

the distance is 6 since the x part stayed on the sam line

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The function is,

⇒ f (x) = 2/3x + 3

Now,

Since, The function is,

⇒ f (x) = 2/3x + 3

Substitute x = 12 in above equation, we get;

⇒ f (x) = 2/3x + 3

⇒ f (12) = 2/3 × 12 + 3

⇒ f (12) = 2 × 4 + 3

⇒ f (12) = 11

Thus, The value of f (12) will be;

⇒ f (12) = 11

last month you swam the 50-meter freestyle in 28.38 seconds. today you swam it in 27.33 seconds. what is your percent of change?

Answers

The distance is the same(50 meters). So we will operate only with numbers 28.38 and 27.33.
The difference is 28.38-27.33=1.05
So the percent of change is (1.05/28.38)*100%≈3.7%
The answer is 3.7%
