Y + 5 = 0
y >= -5
Therefore, you would choose the first answer.

Answer:

y ≥ 0

Step-by-step explanation:

if you put a negative in place of 'x' you would get a negative root which is an imaginary number

Factorize by splitting the middle term 6x-11x+4

Gennadij [26K]

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

(2x - 1)(3x - 4)

Find the area of an equilateral triangle (regular 3-gon) with the given measurement. 9-inch perimeter A = sq. in.

Alona [7]

Answer:

$3.9 in^2$

Step-by-step explanation:

The area of a triangle is given by

$A=\frac{1}{2}bh$

where

b is the base

h is the height

Here we have an equilateral triangle, which has the 3 sides of the same length.

Let's call L the length of one side.

We know that the perimeter of the triangle is

p = 9 in

The perimeter is the sum of the three sides, so:

$p=L+L+L=3L$

Therefore, we find the length of the side:

$L=\frac{p}{3}=\frac{9}{3}=3 in$

Therefore the length is the base of the triangle,

$b=L$

The height can be calculated by considering half triangle: the hypothenuse is equal to L, while one side is equal to half the base (b/2), therefore the height is given by Pythagorean's theorem:

$h=\sqrt{L^2-(\frac{b}{2})^2}=\sqrt{3^2-(\frac{3}{2})^2}=2.6 in$

Therefore, the area of the triangle is:

$A=\frac{1}{2}(3)(2.6)=3.9 in^2$

3. Grad point question for a quiz Graph the inequality. A. x -3 D. x≤-3

LUCKY_DIMON [66]

Answer:

The answer most likely would be x > -3

Step-by-step explanation:

It would be this because it's a opened dot and not a closed one. A closed dot would have the greater or less than sign with the line underneath it

REMEMBER if it is shaded to the right then the inequality points to the right (>). If it is shaded to the left the inequality points to the left (<)
