A proportional relationship is also a direct variation.
The general equation of direct cvariation is
y = kx,
where k is a number.
In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as
y = -x
Answer:
14b
Step-by-step explanation:
Here, we want to get the greatest common factor of the two terms
The greatest common factor can be obtained by finding the expression that factor the given expression
We have this as;
14b(2a + 3)
So the greatest common factor is 14b
The answer should be y=-4x^2
He walked 3 miles in an hour. He would have to also walk 9 laps in 45 minutes to walk the same amount. Not sure what your question is?
So 2.25 is 50% of the original price
let's write original price as x
50% of x = 2.25
0.5 * x = 2.25
divide both sides by 0.5
x = 4.5
The original price is 4.5
To check:
50% * (4.5) =?= 2.25
0.5 * 4.5 =?= 2.25
2.25 = 2.25
Hope this helps.
