In the given equation, as the value of <em>y</em> increase, the value of <em>x</em> also
increases.
- Yes, 4·y = 16·x is a direct variation
Reasons:
A direct variation is a relationship that exists between two variables. It is
also known as a direct proportion which can be expressed as; y = k·x
Where <em>k</em> is a number
The given equation is 4·y = 16·x
Dividing both sides by 4 gives;
Which gives;
y = 4·x
Comparing the above equation with the equation for a direct variation gives;
y = 4·x
y = k·x
Therefore;
k = 4
The equation, y = 4·x, and therefore, the equation from which it is derived, 4·y = 16·x, is a direct variation.

Answer:
The answer would be 2.7. Am not very sure though
Step-by-step explanation:
So what you do is
for example the unkown number is x and the answer you get is y
12-x=y * -15=-140
-140/-15=9.33 (this is y the answer)
12-x=9.3
12-9.3=2.7
To check your answer
12-2.7=9.3
9.3 * -15=-139.5 if you round it then it would be -140
Answer:
the answer is 611.2
how,-3.3x
611.2
=6
there before 614.2 there come always+if there is nothing
then,there is- before-3.3x then rule=
<h3>- + +=-</h3>
so we have to substract it
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets
