The one with domain {8, 3, 1} and range {6, 2, 7, 9}(top-left) is not a function because 3 is being mapped to two different values, 2 and 7.

Determine which equation has the same solutions as the given equation. x2 − 10x − 11 = 0

cupoosta [38]

The equation x² − 10x − 11 = 0 that is equivalent to (x – 5)² = 36. Then the correct option is A.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

The equation is given below.

x² − 10x − 11 = 0

Then the equation can be written as

x² − 10x + 25 – 25 − 11 = 0

(x – 5)² = 36

Then the correct option is A.

The complete question is attached below.

I really need some help

earnstyle [38]

Answer:

CEFA

Step-by-step explanation:

1. $p=2(2x)+2(3x+2)=4x+6x+4=10x+4$

2. $p=2(x)+2(4x+1)=2x+8x+2=10x+2$

3. $p=2(7)+2(x+5)=14+2x+10=2x+24$

4. $p=2(5)+2(4x-3)=10+8x-6=8x+4$

Hope this helps

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 58 dash m-by-5

svetoff [14.1K]

Answer:

We need to find the area of the semicircles + the area of the square.

The area of a square is equal to the square of the lenght of one side.

As = L^2 = 58m^2 = 3,364 m^2

Now, each of the semicircles has a diameter of 58m, and we have that the area of a circle is equal to:

Ac = pi*(d/2)^2 = 3.14*(58m/2)^2 = 3.14(27m)^2 = 2,289.06m^2

And the area of a semicircle is half of that, so the area of each semicircle is:

a = (2,289.06m^2)/2 = 1,144.53m^2

And we have 4 of those, so the total area of the semicircles is:

4*a = 4* 1,144.53m^2 = 4578.12m^2

Now, we need to add the area of the square 3,364 m^2 + 4578.12m^2 = 7942.12m^2

This is nothing like the provided anwer of Val, so the numbers of val may be wrong.

Answer:

Neither A nor B

Step-by-step explanation:

Some of the ordered pairs have numbers that are repeating! Therefore, none of them are functions. Ex. (7, -4) (7, -2)
