Answer:
The y-coordinate of the solution is, 10
Step-by-step explanation:
Given the system of equation:
....[1]
....[2]
Equate the equation [1] and [2] we have;
Add 2x to both sides of an equation:
Subtract 4 from both sides we have;
or
Using perfect square:
⇒We can write the equation as:
then;
⇒
Subtract 3 from both sides we have;
x = -3
Substitute value of x in [1] we have;
⇒
Solution for the given system of equation = (-3, 10)
Therefore, the y-coordinate of the solution is, 10
Answer:
The number of spots in the parking lot if there are 32 parking spots in the first row =111.
Step-by-step explanation:
We are given that a new parking lot is being built for a medical office.
We are given that
The expression representing the number of parking spots in the new lot =
Where x= The number of parking lots in the first row
We have to find number of spots in the parking lot when parking spots in the first row is 32.
The number of parking spots in the first row =x=32
Substitute the value of x in the given expression then we get
Number of spots in the parking lot =
Number of spots in the parking lot=
The number of spots in the parking lot=120-9
The number of spots in the parking lot=111.
Hence, the number of spots in the parking lot if there are 32 parking spots in the first row=111.
