When James family went on the road to the carnival they were stuck in traffic. After a 20 minutes they are were 30 more miles le
Assoli18 [71]

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Gabriella is X years old her sister Felisha is 6 years older than she is their mother is twice as old is Felicia their aunt Tany
Makovka662 [10]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~

Let me lay down the Given, and than I'll solve the question...

<em>Felisha</em> is 6 years older than <em>Gabriella</em><em> - (y)</em>

<em>Their Mother</em> is 2 times older than <em>Felisha</em>

<em>Their Aunt (Tanya - [x] )</em> is X years older than <em>Their Mother</em>

<em /><u><em>We are solving for how old is Tanya? ...</em></u>

**I stated Gabriella with a y instead of an X so that the equation does not look confusing, feel free to replace my y with "<em /><em>Gabriella(X)</em>", when writing/typing your answer...

**When I use the variable <em>Z</em>, this is how many years Tanya is older than the Mother...


To find how many years Tanya is older than the Mother: Z = 2 * (6 + y)

Now... the answer is: X = (2 * (6 + y)) + Z

I stated it this way, because we have to add Felisha's and Gabriella's age first, and than your multiply that age <em>Total</em> by 2 to get the Mother's age...

What are the domain and range of y=-5/6(x+2)^2-8?
marusya05 [52]

Answer:

Domain: allrealnumbers

Range: f(x) <= -8

Step-by-step explanation:

This equation shows that this shape is a parabola that is opening downwards (because of the negative in the -5/6)

This means it has a highest point. The x+2 means the curve is shifted/slid/tranlated to the right 2 units and the -8 at the end shows that it is slid/shifted/translated down 8 units. So the curve only exists starting from -8 and going down. That is the range f(x) <= -8

All upward and downward opening parabolas have a domain of all real numbers.
