The statement " <span>y </span><span>varies directly as </span><span>x </span><span>," means that then </span><span>x </span>increases,<span>y </span><span>increases </span><span>by the same factor so we have: y/x=k
for question 1 then: 15/5=3
so the direct variation equation is y=3x
Now if x=9 you only have to replace x in your equation and you get:
y=3*9=27</span>
30x-12-8x+40
22x-12+40
22x +28
Are those your only answer options?
I have an idea...
Combining 44 (c) and 23 (b) you get 67 243+32>342-67 or 342-(44+23) ==> false Combining 44 (c) and 43 (d) you get 87
243+32>342-87 or 342-(44+43) ==> true
Answer:
A geometric object is represented by its vertices (as position vectors) A geometric transformation is an operation that modifies its shape, size, position, orientation etc with respect to its current configuration operating on the vertices (position vectors).
Here, 2x + 1 = 3x
3x - 2x = 1
x = 1
In short, Solution would be 1 only.
Hope this helps!
