How do I determine the radius of x^2+y^2=25 ?

Answers

Circles!!!

The general formula is:
x^2 + y^2 = r^2
where x and y form the circle while r is the radius.

You already have the problem set up in its general form and you don't want the radius squared... so square root everything.

If you do that then you'll get:
x + y = 5
where 5 is the radius and NOT the radius squared. If you have questions then leave a comment. Good luck!

Find a pair of irational numbers whose sum is irational

Answers

Answer:

√2 and √3

Good Luck!!!

Final answer:

A pair of irrational numbers whose sum is irrational does not practically exist. The sum of two irrational numbers can be either rational or irrational, and this solely depends on the numbers being added together.

Explanation:

The irrational numbers can be defined as any real number that is not a rational number. However, the sum of two irrational numbers is not always irrational. It could be rational or irrational depending on the numbers you're adding. However, you've asked for a case where the sum is also irrational. Let's consider two irrational numbers √2 and -√2. √2 is irrational. Likewise, -√2 is also irrational. However, when added (√2 - √2), they result in 0 which is not irrational. Therefore, it's near impossible to find two irrational numbers whose sum is also irrational.

#SPJ12

Write an equation of a line that has the same slope as 2x – 5y = 12 and the same y-intercept as 4y + 24 = 5x.y = 1/6x - 5/2
y = 2/5x - 6
y = 6x - 2/5
y = 5/2x - 6

Answers

in ax+by=c form
slope=-a/b

y intercept is when x=0


sloope of 2x-5y=12 is -2/-5=2/5

y intercept of 4y+24=5x
4y+24=5(0)
4y+24=0
4y=-24
y=-6
y int=-6

y=mx+b
m=slope
b=y intercept
y=2/5x-6
