Answer:
x<=5
Step-by-step explanation:
Two things
- direction its pointing is always how the sign will look like
- if the circle is shaded it will have an "or equals to" sign; if its blank, there is only the "greater/lesser" sign
Answer:
F=121.61 gr,
Step-by-step explanation:
we see that it is a problem of proportion, so then if the total mass of the sample is the sum of M plus fluorine
the sample weighs 1.38gr M + 0.71gr F = 2.09, where M y F represent :
M=1.38*100/2.09 = 66.02% and
F=0.71*100/2.09 = 33.97%, also
in 358 gr. * 0.3397F = 121.61 gr F
A 9/24 & 16/24
b 72/108 & 36/108 or 12/27 & 9/27
c 10/50 & 30/50 or 5/25 &15/25
d 15/3 & 6/3
A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
Option I
(3x+4)cm =(2x+10)cm
3x-2x=6
x=6
Option II
(3x+4)= (x+12)
3x-x=12-4
2x=8
x=4
Option III
(2x+10)= (x+12)
2x-x=12-10
x=2
