I would assume it's the area of both the sidewalk and pool combined (79ft x 49ft = 3,871) minus the area of the pool alone (75ft x 45ft = 3,375). The area of the sidewalk would then be
496 ft.
From the system of equations given, it is correct to state that:
- System A has two real solutions
- System B has two real solutions
- System C has one real solution.
<h3>What are system of equations?</h3>
System of equations refers to a matrix that has elements which are representative of the coefficients of the given equations.
<h3>What are the solutions to the above systems of equations?</h3>
System A:
x² + y² = 17
y = -1/2x
The two real solutions to the above system is given as:
and
System B:
y = x² - 7x + 10
y = -6x +5
The two real solutions to the above system is given as:
System C
y = -2x² + 9
8x-y = -17
The one real solution is given as:
x = -2, y = 1
