-4.5x-2y=-12.5 and 3.25x-y=-0.75
we first multiply the second equation by -2
(-2)*(3.25x-y=-0.75)=-6.5x+2y=-1.5
add the equation to eliminate the y
so yo get (-4.5x-6.5x)=(-12.5-1.5)
-11x=-11
x=1
now we plug in x into any equation to solve for y
-45x-2y=-12.5 and x=1
(-45*1)-2y=-12.5
-4.5-2y=-12.5
-2y=-12.5+4.5
-2y=-8
y=4
then your answer is x=1 and y=4

Answer:
(3,4)
Step-by-step explanation:
Can't have any point with the same x-value, so it can be anything just can't be (5,y)
Answer:
50yds²
Step-by-step explanation:
area of a triangle equals base times height divided by 2
a=20*5/2
a=100/2
a=50yds²
