Insert x = -1 and y = 4 into the first inequality:-
4 <= -(-1) + 4 = 5

so this fits

Answer: First one

Step-by-step explanation:

Due to slope form which is y=mx + b.

-1 = x and y = 4.

It does not show the one because it would be equal to X, but it does show the negative

Arithmetic average of real nonnegative numbers is always smaller than or equal to geometric average. Group of answer choices Tru

noname [10]

Answer:

False

Step-by-step explanation:

Actually, the arithmetic average (or mean) is always greater or equal than the geometric average. This is known as the Arithmetic-Geometric inequality (AM inequality). Let a,b be two real numbers, then the AM inequality states that

$\frac{a+b}{2}\geq \sqrt{ab}$

To see that the given statement is false, consider a=1, b=3. The arithmetic mean is equal to (1+3)/2=2, and the geometric mean is equal to $\sqrt{1\cdot 3}=\sqrt{3}$ but $2>\sqrt{3}$ , contrary to the statement (arithmetic>geometric in this case).

A flagpole has a height of 16 yards. It will be supported by three cables, each of which is attached to the flagpole at a point

Marta_Voda [28]

Cables are forming 3 right angled triangles the pole being the shared height of them;

(height) b= 12yd
(base) a= 9yd
(hypotenuse) c= ?
Need to find the long side (hypotenuse);

a^2 + b^2 = c^2

12^2 + 9^2 = 225
Take square root of 225 = 15
Then you have;

1x 12yd = 12
3x 9 yd = 27
3x 15yd = 45

Add them up = 84yd of cable needed
