Answer: 3.6
Step-by-step explanation: 3x1.2= 3.6
The line of the equation perpendicular to y=5 and cuts through (-5,-7) will be given by
m(x-x1)=y-y1
where m=slope.
from y=0x+5, the slope of the perpendicular line m=0,
thus the equation will be:
0(x--5)=y--7
0=y+7
y=-7
The equation is y=-7
Answer:
C
Step-by-step explanation:
(a)
2 : 4 ( divide both values by 2)
= 1 : 2
3 : 6 ( divide both values by 3 )
= 1 : 2
Thus 2 : 4 = 3 : 6
(b)
3 : 9 ( divide both values by 3 )
= 1 : 3
Thus 1 : 3 = 3 : 9
(c)
4 : 6 ( divide both values by 2 )
= 2 : 3 ≠ 3 : 2
(d)
10 : 2 ( divide both values by 2 )
= 5 : 1
Thus 5 : 1 = 10 : 2
