babymother [125]

Answer:

15 < 23

Could you include the numbers on D.? Thanks!

Step-by-step explanation:

They've been open for 15 hours, to reach 392 people. They can't be open for more than 23, because that would be more than 600 people. Therefore 23 need to be always GREATER than 15

15 < 23

see if you can find a number line that matches the expression.

Hope this helped! Please mark as brainliet! Thanks!

Me too! I'm an A/B Honor role student, but i get stuck and need help all the time. Not every one is perfect! ^_^

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains
aniked [119]

Answer:

\[y=-2x+13\]

Step-by-step explanation:

Equation of the line CD is given as \[y=-2x-2\]

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by \[y=mx+c\]

\[y=-2x+c\]

But this line passes through (4,5)

Substituting the values in the equation:

\[5=-2*(4)+c\]

=> \[c=5+8=13\]

So the overall equation of the parallel line is given by \[y=-2x+13\]

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

8x - (2x - 13) = 42

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute negative:                                                     8x - 2x + 13 = 42
  2. [Subtraction] Combine like terms:                                                                    6x + 13 = 42
  3. [Subtraction Property of Equality] Subtract 13 on both sides:                        6x = 29
  4. [Division Property of Equality] Divide 6 on both sides:                                 x = 29/6

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                                                                                                  8(29/6) - [2(29/6) - 13] = 42
  2. Multiply:                                                                                                             116/3 - [29/3 - 13] = 42
  3. [Brackets] Subtract:                                                                                           116/3 - -10/3 = 42
  4. Subtract:                                                                                                            42 = 42

Here we see 42 does indeed equal 42.

∴ x = 29/6 is the solution.
