Answer:
The lines have different slopes: first one is -2, the second is 0
There is one solution and it is (3, -3)
Step-by-step explanation:
straight line equation: ax + by + c = 0
slope m= -a/b
the first line has m = -2/1 = -2
the second has m = 0/1 = 0
to find the solution, if needed, simply consider the first equation and put -3 as value of y (the second equation gives you that value straight away y = -3)
so -3 = 2x -3
2x = -3 + 3 so 2x = 0 therefore x = 0
The area and circumference of the circle will be 28.26 square units and 18.84 units, respectively.
<h3>What is the circumference and area of a circle?</h3>
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The circumference of the circle will be
C = 2πr units
From the diagram, the radius of the circle is 3 units. Then the area of the circle will be
A = πr²
A = 3.14 x 3²
A = 3.14 x 9
A = 28.26 square units
Then the circumference of the circle will be
C = 2πr
C = 2 x 3.14 x 3
C = 18.84 units
The area and circumference of the circle will be 28.26 square units and 18.84 units, respectively.

Step-by-step explanation:
Dada la siguiente información:
Costo total= $1,956
<u>Para calculate el valor parcial, debemos usar la siguiente información:</u>
Precio proporcional= costo total* ( 1 - porcentaje de descuento)
50%:
Precio proporcional= 1,956*(1 - 0.5)
Precio proporcional= $978
25%:
Precio proporcional= 1,956*(1 - 0.75)
Precio proporcional= $489
