Answer:

The answer sorta varies, for example

"1² + 2² = 3² " <em>cannot form a triangle</em>, same with 4² + 5² = 10², there are actually more numbers but im not sure XD

LMK if this is wrong <3

Answer:

y = -5/4x - 3/2

Step-by-step explanation:

y2 - y1 / x2 - x1

6 - (-4) / -6 - 2

10 / -8

= -5/4

-4 = -5/4(2) + b

-4 = -5/2 + b

Answer:

16.67% probability of getting 2 blues

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the marbles are selected is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

What is the probability of getting 2 blues?

Desired outcomes:

Two blue marbles, from a set of 4.

$D = C_{4,2} = \frac{4!}{2!(4-2)!} = 6$

Total outcomes:

Two marbles, from a set of 9.

$T = C_{9,2} = \frac{9!}{2!(9-2)!} = 36$

Probability:

$p = \frac{D}{T} = \frac{6}{36} = 0.1667$

16.67% probability of getting 2 blues

Factor the expression

Alex777 [14]

Factor the equation using difference of squares, which says that a^2-2ab+b^2=(a-b)^2.

a is 2 since the square root of 4 is 2 and b is 5 because the square root of 25 is 5.

Final answer: (2x-5y)^2

This is a simple "solve for x" equation.
5k-2k=12
3k=12
k=4
You should try doing some more on your own, as this will be coming up a lot in the future.
