Set equal to each other since both equal 90
5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0
5(0)-6y=-90
-6y=90
divide by -6
y=-15
(x,y)
(0,-15)
Answer:
0.07
Step-by-step explanation:
to find the IQR you do Q3-Q1
2.00-1.93
Treat ast fraction
96/132
divide by 2,3,5,7 or factors starting from 2
96/2=48
132/2=66
48/66
divide 2
48/2=24
66/2=33
24/33
divide 3 since cannot divide 33 by 2
24/3=8
33/3=11
8/11
8:11
answer is 8:11
It should be negative one (-1)
