we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form 
in this problem we have

so
<u>Find the value of the constant k</u>

substitute


the equation is equal to

<u>Find the value of y when
</u>
substitute the value of x in the equation


therefore
<u>the answer is</u>

Answer:
If you mean y = 4x + 5, then the answer is 5 (the height would be 5 feet)
Step-by-step explanation:
0.00037 = 3.7×10^-4
37,000 = 3.7×10^4
_____
The exponent of 10 is the place-value multiplier that the most-significant digit has.
In the first number, the most-significant digit (3) is multiplied by 0.0001 to find its place value. Of course 0.0001 = 10^-4.
In the second number, the most significant digit (3) is multiplied by 10,000 to find its place value. You know that 10,000 = 10^4.
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35
minus original aera
which is 5 by 7 which is 35
4a²+24a+35-35=4a²+24a
3rd option I think, can't tell which is which
If you mean what goes in the blanks, it is 5 for the first empty box and 10 for the second empty box.
