Answer:

Where's the x?

I am assuming that the problem must be

-3 + 42 > 3x

if that is true, then

<u>x < 13</u>.

As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and

39 > 3 [39 is always greater than 3]

Step-by-step explanation:

Let me know if you need a step by step.

Answer:

D) x < -15

Step-by-step explanation:

-3x - 42 >3

Add 42 to each side

-3x - 42+42 >3+42

-3x > 45

Divide each side by -3.  Remember to flip the inequality since we are dividing by a negative

-3x/-3 < 45/-3

x < -15

not really sure how you want this solved but the equation itself is true

<u>Part A</u>

<u />\overline{AC} and \overline{BD}

<u>Part B</u>

Diagonals of a parallelogram bisect each other, so

BE=ED \implies 2x+3=3y-4 \implies 3y=2x+7 \implies y=\frac{2}{3}x+\frac{7}{3}\\\\AE=EC \implies y+4=4x-6 \implies y=4x-10

Solving by substitution,

\frac{2}{3}x+\frac{7}{3}=4x-10

Multiplying both sides by 3,

2x+7=12x-30\\\\37=10x\\\\x=3.7

So, y=\frac{2}{3}\left(\frac{37}{10} \right)+\frac{7}{3}=\frac{24}{5}

<u>Part C</u>

<u />BE=ED=2(3.7)+3=10.4\\\\AE=EC=4(3.7)-6=8.8

\therefore BD=2(10.4)=20.8, AC=2(8.8)=17.6

Does the graph represent a function and if so, why?
hichkok12 [17]

Answer:

No

Step-by-step explanation:

Definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output

Here we have more than one output for one input:

  • x=-1 => y= -1, 0, 1
  • x= 1  => y= 1, 2, 3

So this is not a function

Shivani played a video game with three levels. It took her 30 minutes to beat the first level and 1 hour and 45 minutes to beat
Georgia [21]

Answer:

9:30 am

Step-by-step explanation:

  1. Add 30 minutes + 30 minutes to get 60 minutes, which is one hour.
  2. Add 1 hour to 1 hour and 45 minutes to get 2 hours and 45 minutes.
  3. Subtract 2 hours from 12:15 pm, to get 10:15.
  4. That'll leave you with just 45 minutes left. To make it easier than subtract 45 minutes from 10:15, subtract 15 minutes from 10:15, to end up at 10:00 am.
  5. 45 minutes - 15 minutes = 30 minutes, so then you subract 30 minutes from 10:00 am, and you end up at 9:30 am, which is your final answer
