Y/7 =2/x do those show direct variation ​

Mathematics

saul85 [17]2 years ago

Answer:

y/7 =2/x does not show direct variation

Step-by-step explanation:

y/7 =2/x is one equation, so please ask, "Does y/7 =2/x represent direct variation?"

Let's solve this y/7 =2/x for y:  Mult. both terms by 7.

We obtain y = 14/x.  This does NOT have the form of a direct proportion because that x is in the denominator.

So, no, y/7 =2/x does not show direct variation.

If y=kx, where k is a constant, and y=24 when x=6, what is the value of y when x=5?A. 6B. 15C. 20D. 23
Marizza181 [45]

First, we will find the value of k

We can do this by sybstituting y=24, x=6 in;

y=kx and then solve for k

24= k(6)

divide both-side of the equation by 6

24/6 = k

4 = k

k=4

Then when x = 5, we will substitute x=5 and k=4 in; y=kx and then solve for y

y= (4)(5)

y = 20

the direction angle for vectors 135° the X component of the vector is -3 what is the Ywhat is what what is the Y component of th
blagie [28]
Well, the X component (assuming x is the horizontal) is equal to RCosZ

Where Z is the angle and R is the size of the resultant

Substitute into formula :

X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)

The vertical component (or Y component) is equal to RSinZ

Vertical component = RSinZ
= 4.24264... × Sin135°
= 3

The answer is 3
