What is the distance between the points (-9,9) and (-4,-3)

Mathematics
1 answer:
Liula [17]3 years ago
4 0

Answer: 13 units

Step-by-step explanation:

d = sqrt[(-3-9)^2 + (-4 - - 9)^2]

= sqrt [(-12)^2 + (5)^2]

= sqrt (144 + 25)

= sqrt 169

= 13

Jason states that Triangle A B C is congruent to triangle R S T. Kelley states that Triangle A B C is congruent to triangle T S
Brilliant_brown [7]

Answer:

The correct option is;

Jason's statement is correct. RST is the same orientation, shape, and size as ABC

Step-by-step explanation:

Here we have

ABC = (2, 1), (3, 3), (4, 1)

RST = (-4, -2), (-3, 0), (-2, -2)

Therefore the length of the sides are as follows

AB = \sqrt{(2-3)^2+(1-3)^2} = \sqrt{5}

AC = \sqrt{(2-4)^2+(1-1)^2} =2

BC = \sqrt{(3-4)^2+(3-1)^2} = \sqrt{5}

For triangle SRT we have

RS = \sqrt{(-4-(-3))^2+(-2-0)^2} = \sqrt{5}

RT = \sqrt{(-4-(-2))^2+(-2-(-2))^2} = 2

ST = \sqrt{(-3-(-2))^2+(0-(-2))^2} = \sqrt{5}

Therefore their dimensions are equal

However the side with length 2  occurs between (2, 1) and (4, 1) in triangle ABC and between (-4, -2) and (-2, -2) in triangle RST

That is Jason's statement is correct. RST is the same orientation, shape, and size as ABC.

laiz [17]

Answer:

x= 3.21

Step-by-step explanation:

25- 21.79= 3.21

the equation equals to 25 so you need to find what x is by subtracting the other value

Hope this helps
