Answer:
Number 5 is ' 2(x) + 1 = y '
I dont know how to solve number 6.
Step-by-step explanation:
you take your x variables and compare them to each other and compare them to the y variables. each x variable goes into the y variable 2 times. thats where the 2(x) comes from. then once yiu do that for all your x variables, you must look to see what they have in common. in this case all of them are one digit less than the y value. so you add that to your equation and it become ' 2(x) + 1 = y '
First take the fractions and find their common denominator:

x 4 =

Now you can add the fractions:

Now add your whole numbers and the fraction:
1+1= 2 >> 2+

= 2

yards
Now subract 2

from 5:
5-2

=
2
yards
Answer:
Domain: [0, ∞)
Range: [7850, ∞)
Step-by-step explanation:
A function is defined by the set of ordered pairs having different output values for every input value.
In the graph attached, for every input value (x-coordinates) there is a unique output (y-coordinates) value.
Therefore, graph represents a function.
Domain of the given function → [0, ∞)
Range of the function → [7850, ∞)
