Write the equation of the line that passes through the point (-5,5) and has a slope of -8/5A) y= -8/5 x - 3
B) y= -8/5x+3
C) 3x - 5y =0
D) 5x-3y=0

Answers

Answer 1
Answer:

Answer:

A) y= -8/5x -3

Step-by-step explanation:

This is your current equation: y= -8/5x + b. I would plug in your point to the equation. It should look like this: 5= -8/5(-5)+b. Multiply -8/5 by -5 to get 8. This is what you should have: 5=8+b. Subtract 8 from both sides to get -3=b. So, this is your final answer: y= -8/5x -3. So, A is the correct answer. Hope this helped!

PLEASE HELP ASAP!!!Which sets of side lengths represent Pythagorean triples? Check all that apply.

Answers

Answer with Step-by-step explanation:

For the Pythagorean triples, the square of largest number must be equal to the sum of squares of remaining two numbers.

1,2,5

5²=25

1²+2²=5

25≠5

Hence, it is not a Pythagorean triple.

6,8,14

14²=196

6²+8²=100

100≠196

Hence, it is not a Pythagorean triple.

8,15,17

17²=289

8²+15²=289

Hence, it is a Pythagorean triple

10,24,26

26²=676

10²+24²=676

Hence, it is Pythagorean triple

15,20,30

30²=900

15²+20²=625

900≠625

Hence, it is not a Pythagorean triple

28,45,53

53²=2809

28²+45²=2809

Hence, it is a Pythagorean triple

8,15,17 is one, 10,24,26 is one, and 28,45,53 is one

The sum of three consecutive integers is 1,623

Answers

Set the unknown integer to x. Since they are consecutive integers the next will be x+1 and the next x+2. So

x + x+1 + x+2 = 1623
3x + 3 = 1623
3x = 1620
x = 540

x+1 = 541
x+2 = 542

The consecutive integers are 540, 541, and 542.

Order from least to greatest 0.6 4/5 0.75

Answers

Because the majority is in decimal form, you'll have to change the fraction to a decimal too so that it would be easier to solve this problem. 4/5 in decimal form is 0.8

So, the order from least to greatest is

0.6, 0.75, 4/5

Hope this helps :)

Answer:0.6,0.75,4/5
