Are these numbers a Pythagorean triple? yes or no

Mathematics
1 answer:
Illusion [34]3 years ago
3 0

Answer:

Yes

Step-by-step explanation:

You know if the numbers are in a Pythagorean triple if the sum of the squares of the two smaller numbers is equal to the square of the largest number according to the Pythagorean Theorem: a^2+b^2=c^2.

Here, a = 15 and b = 20. Let's see if: 15^2+20^2 equals 25^2.

15^2 = 225

20^2 = 400

15^2 + 20^2 = 225 + 400 = 625

25^2 = 625

Since 15^2 + 20^2 does indeed equal 25^2, we know that this is a Pythagorean triple.

Hope this helps!

you are asked to solve for y in the equation -3=5y-2x , given that x= -4 what is the first step you will take
Genrish500 [490]
First step is replacing x with -4. => -3=5y+8 => 5y= -8-3 => y =-11/5

Write an equation of the form y=mx for the pairs (-1,4) and (1,-4)
hram777 [196]
Y = mx
We just need to find the slope:

y2 - y1 / x2 -x1 = -4 - 4 / 1 - - 1 = -8/2 = -4/1 = -4

so:  y = -4x

Hope that helps! :)

What is the vertex of y=x^2+4x+3
AnnyKZ [126]

Answer:

(-2, -1)

Step-by-step explanation:

This is a quadratic equation in standard form, and a = 1, b = 4 and c = 3.

The x-coordinate of the vertex is given by the formula

        -b                                                                         -4

x = --------- which here has the numerical value x = -------- = -2

        2a                                                                           2

Finally, we evaluate y=x^2+4x+3 at x = -2 to find the y-coordinate of the vertex:

y = (-2)^2 + 4(-2) + 3 = -1

The vertex is at (-2, -1).
