//I'll let x = $5, y = $10
x + y = 13
5x + 10y = 90
So, y = 13 - x
5x + 10(13 - x) = 90
5x + 130 - 10x = 90
-5x = -40
x = 8

Answer:
- width 117 feet
- length 292 feet
Step-by-step explanation:
Let w represent the width of the field. Then w+175 is its length. The perimeter is ...
P = 2(L+W)
818 = 2((w+175) +w) . . . . . fill in given values
818 = 4w +350 . . . . . . . . . simplify
468 = 4w . . . . . . . . . subtract 350
117 = w . . . . . . . . divide by 4
w+175 = 292 . . . . find the corresponding length
The width of the field is 117 feet; the length is 292 feet.
It is the graph in the middle because x can only have one y.
Hope that this helps :)
Answer:
Step-by-step explanation:
Here we can see that the parent function is 
and the translated function is g(x). f(x) is a parabola.
Rule says that any factor if multiplied by f(x) is going to contract the graph towards the y axis and vice versa.
Similarly any factor if f(x) is divided by some factor it is going to be stretch the graph away from the y axis and vice versa.
Here we can see that the translated graph g(x) is stretched away from the y axis with reference to the parent function f(x). Hence as per he rule discussed above, we get a preliminary information that the parent function f(x) is being divided by some factor.
now we are given that
Where as
{as given in the graph}
Hence
at x=3 , f(x) = 9 and g(x) = 1 , and also we have discussed above that f(x) is divided by some factor. Hence 
The height of the flagpole with an angle of elevation to the top of the pole of 31° is 60.086 feet
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a triangle.
Let h represent the height of the flagpole, hence:
tan(31) = h/100
h = 60.086 feet
The height of the flagpole with an angle of elevation to the top of the pole of 31° is 60.086 feet
