X= number of goals
y= number of points
x+y=18
3x+y=28
(3x+y)-(x+y)=28-18
2x=10
x=5
y=13
Answer:
one solution;y=-4
Step-by-step explanation:
-2y-7+-5y=13-2y
-7y-7=13-2y
-5y-7=13
-5y=20
y=-4
Answer:
4in^2 or 16.649110640674in^2
Step-by-step explanation:
base surface area is 4in^2
total surface area is 16.649110640674in^2
Option D:
are the coordinates of the point P
Explanation:
It is given that "A coordinate grid shown from negative 2 to positive 2 on x-axis and negative 2 to positive 2 on y-axis. There are 4 grid lines between a whole unit of the grid".
Thus, the value of each grid is 
It is also given that, "A point labeled P is shown at the intersection of 8 grid lines to the left of the y-axis and 4 grid lines above the x-axis".
Since the point P lies on the left of the y-axis and above the x-axis, the x-value will be negative and y-value will be positive.
Thus, the value of x-axis is given by

And the value of y-axis is given by

Thus, the coordinates of the point P is 
Hence, Option D is the correct answer.
