Answer:
2 is the constant of proportionality in the equation y = 2x .
Step-by-step explanation:
Definition of constant of proportionality
When two variables are directly proportional to each others .
Let us assume that u and v .
u \propto vu∝v
Than the equation becomes u= kv
Where k is called the constant of proportionality .
Thus in the question x and y are proportional variables .
i.e
y \propto xy∝x
y = kx
Where k is called the constant of proportionality .
Compare the equation y = kx with y=2x .
Thus
k = 2
Therefore 2 is the constant of proportionality in the equation y = 2x
the explanation is not mine only the answer
Answer:
it's not greater than it would be 2x-3y because you can add then together because the not the same variable
Step-by-step explanation:
When n is multiplied by -5/8 and the product is equal to -4, it's really saying
-5/8n = -4
To solve an equation like this we can use properties of equality
For this problem there is only one step, being dividing both sides by -5/8
-4 divided by -5/8 = 32/5
Answer: 32/5 or 6 2/5
I hope this helps!
8.3 + 3.5y − 0.5(16y − 5) = -4.5y + 10.8
Answer: x + 0.8 = 101.1
Step-by-step explanation:
Let x represent Connor's temperature last night. Connor's temperature was 0.8 degrees Fahrenheit higher this morning than it had been last night. This means that his temperature this morning will be
x + 0.8 degrees Fahrenheit
His temperature this morning was 101.1 degrees Fahrenheit. Therefore, the equation of the situation will be
x + 0.8 degrees Fahrenheit = 101.1 degrees Fahrenheit
