Answer: D (5/2, -17/4)

Step-by-step explanation:  Using elimination your goal is to get rid or 1 variable  so you can solve for the one that's left.  By adding the -2y and 2y you will get 0.  You will also add the 3x+x (4x) and -1+11 (10).  You have now gotten rid of the y and have 4x=10.  By dividing each side by 4 we now know x =2.5.  D is the only possible solution with x=2.5 (5/2) but to solve for y you plug 2.5 in to an equation as x so) x-2y=11

                                                                           2.5-2y=11

                                                                            -2y=8.5                                                                        Answer D (5/2,-17/4)                                      y=-17/4 (4.25)

PLEASE HELP!!!<br> Question is above^
julsineya [31]

Answer:

C

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 9, 2) and (x₂, y₂ ) = (- 4, 2)

d = \sqrt{(-4+9)^2+(2-2)^2}

  = \sqrt{5^2+0^2} = \sqrt{25} = 5 → C

The length of a rectangle is 6 more than twice its width. The
Whitepunk [10]

Answer:

The answer is option (C). The width of the rectangle=6 inches

Step-by-step explanation:

<em>Step 1: Determine the dimensions of the rectangle</em>

width=w

length=w+6

<em>Step 2: Determine the perimeter of the rectangle</em>

P=2(L+W)

where;

P=perimeter

L=length

W=width

In our case;

P=36 inches

L=w+6

w=w

replacing;

2(w+w+6)=36

2(2 w+6)=36

4 w+12=36

4 w=36-12=24

4 w=24

w=24/4=6

W=6 inches

L=6+6=12 inches

The width of the rectangle=6 inches

Evaluate 2 sin 60° + tan 45° + cos²60°​
DerKrebs [107]

Answer:

1.25+√3 or 2.9821 to the nearest ten thousandth.

Step-by-step explanation:

sin 60 = √3/2,  tan 45 = 1 and cos^2 60 = (1/2)^2 = 1/4

So we get 2 *√3/2 + 1 + 1/4

= √3 +  1.25
