AC is perpendicular to BD
so
3x + 9 = 90
3x = 81
x = 27
answer
x = 27
---------------------------------------
in case if you need to find y
2x + y = 90
2(27) + y = 90
54 + y = 90
y = 90 - 54
y = 36
It depends because u have to show us the diagram since we have to know if it is opposite or adjacent to the angle! Anyways I think u can solve it on your own! The question might have something to do with trigonometry like cos sin and tan! Remember the area of a triangle is 1/2*base*height
Answer:
B
Step-by-step explanation:
Recall that functions are defined only if for each value in the domain produces one and only one value in the range.
If we view the relations in the questions as x-y coordinates, this means that for every x-value, you can only have one y-value
Lets evaluate the options:
A) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
C) we can see that for x = 3, this gives 2 possible values for y i.e (3,-8) and (3,8) (hence this is not a function)
D) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
the only choice where this doesn't occur is choice B
X=8 I’m not that to sure but hope i helped!
Answer:
Amount spent by Tony = $49
Amount spent by Molly = 2 * 14
[49] + [2*49 + 14 ] = $161 = amonut spent by both
