Either graphs A or B.

Answer:

C) Graph B

Step-by-step explanation:

All of these equations have the line y = -2x - 2 graphed.

In the inequality, we have the symbol greater than or equal to. This tells us the line drawn must be solid, not dashed. This means the correct graph is either B or D.

Since it is greater than or equal to, the shaded area must be above the line. This is graph B.

The area of a square is 4 square meters. How long is each side? Please show every step.

inessss [21]

Since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.

So, all of the sides of the square are 2 meters long.

Solving quadratic equation using the completing method. (a).x^2+6x+1=0

irina1246 [14]

Answer:

$x = -3 + 2\sqrt2 \ , \ x = -3 - 2\sqrt2$

Step-by-step explanation:

x² + 6x + 1 = 0

a = 1 , b = 6 , c = 1

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{-6 \pm \sqrt{36-4}}{2}\\\\x=\frac{-6 \pm \sqrt{32}}{2}\\\\x= \frac{-6 \pm \sqrt{16 \times 2}}{2}\\\\x = \frac{-6 +4\sqrt2 }{2}\\\\x = -3 + 2\sqrt2 \ , \ x = -3 - 2\sqrt2$

Consider the numbers 0, 10, 20, 30, and 40. Multiply each by 4 and compare the result to 60 to determine into which of the follo

olya-2409 [2.1K]

Answer:

b) 10 to 20

Step-by-step explanation:

You have to multiply each of the given numbers by 4, and add 8 to that result.

So:

0*4+8 = 8

10*4+8 = 48

20*4+8 = 88

30*4+8 = 128

40*4+8 = 168

And 60 is between the result of 10 and 20, so that's the interval you have to select.

The correct answer is b) 10 to 20

Please I need help with this question

Anna007 [38]

Answer:

1. No

2. No

3. No

4. No

Step-by-step explanation:

y=2 so you multiply your x by 2 and you should come out with your y

your y should be 1 * 2 = 2 but is 9 ---->for (1, 9)

your y should be -6 * 2 = -12 but is 2 ---->for (-6, 2)

your y should be 2 * 2 = 4 but is -8 ----->for (2, -8)

your y should be 0 * 2 = 0 but is -4 ----> ( 0, -4)

side note -I'm sorry if you get it wrong,hopefully it's right though.
