So slope is rise/run so 5/1 would be your slope. Hope this helped.

Solve and graph the absolute value inequality: |2x + 4| > 14.

Aloiza [94]

Answer:

"number line with open circles on negative 9 and 5, shading going in the opposite directions."

Step-by-step explanation:

Your inequality doesn't include an equal sign so there will be no closed holes. It will only be open holes.

|u|>14 means that the number u has to be greater than 14 or less than -14. These numbers I describe just now all have a distance greater than 14 from 0.

So |u|>14 implies u>14 or u<-14.

But we are solving |2x+4|>14 so this implies we have 2x+4>14 or 2x+4<-14.

2x+4>14

Subtract 4 on both sides:

2x >10

Divide both sides by 2:

x >5

2x+4<-14

Subtract 4 on both sides:

2x <-18

Divide both sides by 2:

x <-9

So our solution is x>5 or x<-9.

Graphing!

-----------(-9)---------------------------------(5)---------------

So we shaded to the right of 5 because our inequality says x is bigger than 5.

We shaded to the left of -9 because our inequality says x is less than -9.

A number is selected from the set (1, 2, 3, 5, 15, 21, 29, 38, 500). If equal elemental probabilities are assigned, what is

Katen [24]

Answer:

$\frac{7}{9}$ OR 77.78%

Step-by-step explanation:

So, we first need to find out how many numbers fit the "less than 29 or odd" group.

This would be: 1, 2, 3, 5, 15, 21, and 29, which is a total of 7 numbers.

Next, we figure out the total amount of numbers in the population.

This would be: 1, 2, 3, 5, 15, 21, 29, 38, and 500, which is a total of 9 numbers.

Finally, we put the first number (7) over the total (9) = $\frac{7}{9}$

$\frac{7}{9}$ is now able to be written in a percentage, if you need.

The probability is $\frac{7}{9}$ OR 77.78%

Write the following statement as a conditional statement. <br> Every week has seven days.

Vedmedyk [2.9K]

Definition: A conditional statement, symbolized by p q, is an if-then statement in which p is a hypothesis and q is a conclusion. The logical connector in a conditional statement is denoted by the symbol $p\Rightarrow q$ .
