Irect Variation

Mathematics
1 answer:
Anit [1.1K]2 years ago
4 0

For this case we have to by definition, if "y" varies directly with "x" then it is true that:

y = kx

Where:

k: Is the constant of proportionality

We find the constant "k" according to the given data:

14 = k (-4)\\k = - \frac {14} {4} = -\frac {7} {2}

Thus, the constant of proportionality is - \frac {7} {2}.

Now, we find the value of "y" when x = -6:

y = - \frac {7} {2} (- 6)\\y = \frac {42} {2}\\y = 21

Thus, whenx = -6, the value of y is 21.

ANswer:

y = 21

Use common factors to write two fractions equivalent to 80/140
9966 [12]

Answer:

80/140 = (80:20)/(140:20) = 4/7

4/7 = (4*4)/(7*4) = 16/28

4/7 = (4*5)/(7*5) = 20/35 not 20/28 not 20/32

4/7 = (4*5.5)/(7*5.5) = 22/38.5 not 22/37

Translate the given statement into propositional logic using proposition provided :
olya-2409 [2.1K]

Answer: m ⇒ e ∨ p

Step-by-step explanation:

First look at the statement and locate the connectives ( these are words which connect sentences such as: and, or, implies, is equivalent and not.) Each of these connectives have a symbol/ variable.  

  • In this case the connectives are "only if" and "or" these are important because we will not attach propositional variables to them, where:

⇒ = " only if"

∨ = "or"

  • Convert the phrases into variables where:

m = " You can see the movie"

e = "You are over 18 years old"

p = " you have the permission of a parent"

  • Construct the statement sequentially.

You can see the movie (m) only if (⇒) you are over 18 years old (e) or (∨) you have the permission of a parent (p)

  • Remove the phrases and you'll have your answer:

m ⇒ e ∨ p
