Answer:
x=1/2, y=2;
Step-by-step explanation:
First pair:
2x-5y =-9
4x+5y=12
Add them together:
6x=3
x = 1/2
2(1/2) - 5y =-9
1-5y = -9
1+9=5y
y=10/5=2
Answer: p=7/2=3.5
Step-by-step explanation:
Given
-4p+9=-5
Subtract 9 on both sides
-4p+9-9=-5-9
-4p=-14
Divide -4 on both sides
-4p/-4=-14/-4
p=7/2=3.5
Hope this helps!! :)

Answer:
You can find the point of intersection of the line with the y-axis and the the point of intersection of the line with the x-axis. See the graph attached.
Step-by-step explanation:
Find the intersection with the y-axis. Substitute
into the equation and solve for y:

≈3.33
Find the intersection with the x-axis. Substitute
into the equation and solve for x:


Now, you know that the line passes through the point (0,3.33) and (-10,0). Now you can graph the function. (Observe the graph attached)
15 divide 30 by 2 and you have your answer
