Which relation is also a function?

2 answers:

8 0

A function will not have any repeating x values...they all have to be different. They can have repeating y values, just not the x ones.

so ur sets of numbers are all set up like (x,y). Now look through ur answer choices and which one has all different x values ? That will be ur function.

ur answer is : { (-4,-3), (0,-3), (1,-3), (4,-3)}.....and as u can see, all the x values {-4,0,1,4} are different.

What is the value of X? (giving brainliest and thanks to all!)

Jlenok [28]

Answer:

I believe it is A

Step-by-step explanation:

I dont quite remember the formula, but I belive that 30 would be correct because if im remembering correctly the formulas are "a + b = c" and "c - (a/b) = (a/b)

a/b = a or b, depending what they give you

a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4

Norma-Jean [14]

Answer:

Option b which is $2x^2+6x+3=0$

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is $-x^2+8x+2=0$

Discriminant from the equation we will find by the formula

$D=b^2-4ac$

Here, a=-1,b=8 and c=2 on substituting the values we will get

$D=8^2-4(-1)(2)=72$

Hence, option a is incorrect.

Now, we will consider option b which is $2x^2+6x+3=0$

Here, a=2,b=6 and c=3 on substituting the values we get

$D=(6)^2-4(2)(3)=12$

Hence, option b is correct

Therefore, option b is the required answer.

Kate has a kite with the dimensions shown below. What is the value of X?

sergij07 [2.7K]

Hey there! :D

We will use the properties of similar triangles to figure this out.

We will use two triangles inside the kite, with sides with the value of "x".

Smaller triangle:

Smaller side= 11

Bottom side= x

Bigger triangle:

Smaller side= x

Bottom side= 25

$\frac{11}{x} = \frac{x}{25}$

Cross multiply.

25*11= 275

x*x= $x^{2}$

Find the square root.

√275= 16.583....

Or 5√11.

I hope this helps!
