Using the process of elimination, we will be able to determine the answer. So, 5x+3y=-10 multiply it by *3 to change the equation into 15x+9y=-30. Then to change 3x+5y=-6 multiply it by *5, to change it into 15x+25y=-30. So now with these two equations 15x+9y=-30 and 15x+25y=-30, use subtraction to get rid of the variable x.
Thus,
15x+9y=-30
-
15x+25y=-30
which will leave you with
-16y=0
thus, y=0
Then, plug y back into the original equation to find x
5x+3(0)=-10
5x=-10
x=-2
Thus the point of intersection is (-2,0)
-2 being the x, and y being 0.
Answer:
the answer would be infinite solution
Step-by-step explanation:
Answer:
15 m/sec
1 km = 1000 m
1 hr = 60 min
1 min = 60 sec
1 hr = 60 × 60 sec
So, 15 m/sec = 15 × (60 × 60)/1000 km/hr
54 km/hr
Answer:
0.05
Step-by-step explanation:
this is because the total probability always adds up to 1
