Answers:
- The direct variation equation is y = 5x
- If x = 4, then y = 20
=================================================
Explanation:
Let's say that the letter k replaces the green box
We have the equation y = kx
Plug in (x,y) = (7,35) to get the equation 35 = k*7
Dividing both sides by 7 leads to k = 5
Therefore, the direct variation equation is y = 5x
We can check this by plugging in x = 7
y = 5x
y = 5*7
y = 35
So x = 7 leads to y = 35 as expected.
-------------
Do the same for x = 4
y = 5x
y = 5*4
y = 20 when x = 4
Side note: direct variation equations always go through the origin.
I think ordered pair D would be the correct one
68*x/100=48
=> 68*x=4800
=> x=4800/68
=> x~=70.58
P.S: * means multiply, ~= means approximation, / means divide
Reflexive Property, the property where the quantity equals itself.
