Answer:x=4

Step-by-step explanation:

You can split this up into two equations

x-4=0

x+5=0

To solve each:

x-4=0

Add 4 to each side

x=4

------------

x+5=0

Subtract 5 from each side

x=-5

So your two solutions are -5 and 4 but you want the positive one so the answer is x=4

PLEASE HELP!!
Olegator [25]

Answer:

About 15%

Step-by-step explanation:

Since the weather is good, this means that 500 flights are affected because 50% of the flights experience good weather and 50% of the flights experience bad weather.

there will be 75 flights that are delayed due to causes other than bad weather

if you assume that all of the flights that are not caused by bad weather occur in good weather, then the probability would have to be 75 / 500 = .15 = 15%.

How far is the point described by the ordered pair (4,5)<br>from the x axis?​
weeeeeb [17]

Answer:

<h2>The point is 4 units away from the x-axis.</h2>

Step-by-step explanation:

The given ordered pair is (4, 5).

Remember, in a ordered pair, the first number is about the number of units used horizontally, and the second number is about the number of units used vertically.

So, this point is 4 units right side of the origin and 5 units upside of the origin.

Therefore, the point is 4 units away from the x-axis.
