Step-by-step explanation:

Step 2: -2x - 3 = x - 18

In order to go to Step 3, we must remove the -2x term from the left. In order to do this, we add 2x on both sides:

-2x - 3 + (2x) = x - 18 + (2x)

=> Step 3: -3 = 3x - 18.

Hence the answer is Addition Property of Equality. (A)

Need help plz due on Monday I believe
ra1l [238]

Answer:

1(a) = 10

1(b) = 9

1(c) = 12

2(a) = 8

2(b) = 10

2(c) = 1

Step-by-step explanation:

1(a) = 22 - 2.6

     = 22 - 12 = 10

1(b) = 6 - 1/4 . 16 + 21 / 3

     = 6 - 16/4 + 7

     = 6 - 4 + 7

     = 9

1(c) = (8-5). (5-3)^2

     = 3*2^2

     = 3*4

     = 12

2(a) = 4(x-2)/(x-1) when x = 0

       = 4(0-2)/ (0-1)

       = 4*-2/-1

       = -8 / -1

       = 8

2(b) = (-3x^2 + 4) / 4 when x = -2

       = (6^2 + 4) / 4

        = (36 + 4) / 4

       = 40 / 4 = 10

2(c) = [-2x/4 + 4*(x-1)] / x^2 - 1 when x = 2

      = (-1 + 4 * 1) / 4 - 1

      = 3 / 3

      = 1

Look at the rectangle and the square: Ada says that the length of diagonal SQ is two times the length of diagonal OM. Is Ada cor
Musya8 [376]

Answer:

No, she is wrong.

Step-by-step explanation:

A diagonal of square or rectangle is equals to hypotenuse of a triangle. So you can apply Pythagoras Theorem to solve it :

{c}^{2}  =  {a}^{2}  +  {b}^{2}

Rectangle,

{qs}^{2}  =  {rs}^{2}  +  {qr}^{2}

{qs}^{2}  =  {16}^{2}  +  {8}^{2}  = 320

qs =  \sqrt{320}  = 17.9 \: inches

Square,

{om}^{2}  =  {lo}^{2}  +  {lm}^{2}

{om}^{2}  =  {8}^{2}  +  {8}^{2}  = 128

om =  \sqrt{128}  = 11.3 \: inches

Given that QS is 17.9 and OM is 11.3. So SQ is not 2 times greater than OM.

17.9 \div 11.3 = 1.58 \: (not \: equals \: to \: 2)

What’s the right answer?
galina1969 [7]

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

I am unable to read all of the options in the picture you provided but I hope this helps! (:
