The function f(x)=5x+4f(x)=5x+4 models the height of a tree, where x represents the years since the tree was planted for year 3
Romashka [77]
"<span>all real numbers between 3 and 10 inclusive" could not be the answer, because these are x-values (values of the independent variable).

"</span><span>all real numbers between 19 and 54 inclusive" is the range.  Why?  Because in year 3, f(3) = height of tree = 5(3) + 4 = 19 feet.  

In year 10, f(10) = 5(10) + 4 = 54 feet. </span>

Eugenia walked all the way to school at 3 mph then realized she forgot her math book (how could she?!), so she ran back at 7 mph
kondor19780726 [428]

Let us say distance between Eugenia's home and school is x miles.

Speed of Eugenia when she walked from home to school = 3 mph

Speed of Eugenia when she walked from school to home = 7 mph

Total time taken = 45 minutes or 0.75 hours

We know that the speed distance formula is given by:

speed=\frac{distance}{time}

time=\frac{distance}{speed}

Time taken by Eugenia when she walked from home to school = x/3 hours

Time taken by Eugenia when she walked from school to home = x/7 hours

Total time taken = x/3+x/7

So forming an equation we have,

\frac{x}{3}+\frac{x}{7}=0.75

Taking lcd of 7 and 3 as 21,

\frac{7x}{21}+\frac{3x}{21}=0.75

\frac{10x}{21}=0.75

10x=15.75

Dividing both sides by 10 , we have

x= 1.575

Answer: So we can say that the distance between Eugenia's house and school is 1.575 miles.
