the value of y varies directly with X. Which function represents the relationship between X and Y if y equals 15/6 when x equals
Maru [420]

Answer:

y = (1/8)x

Step-by-step explanation:

The relevant basic formula is y = kx, where k is the constant of proportionality.

We must find k.  To do this, let y = 15/6 and x = 20 in the above formula:

15/6 = k(20)

We solve for k by dividing both sides by 20:  15/(6*20) = k = 1/8

Then the specific formula for this situation is y = (1/8)x

Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice.
In-s [12.5K]

Answer:

Beatrice's age is 34

Step-by-step explanation:

Beatruce = B

Andrew = B+2

Chris= B-3

B+(B+2) +(B-3 )= 67-B

3B-1 = 67-B

2B -1 = 67

2B= 68

B = 34

Beatrice is 34

Andrew is 36   (34+2)

Chris is 31 (34-3)

36+31 = 67

How do you find the phase shift of the trig function y=4sin(pieX+2)-5
max2010maxim [7]

The phase shift is the value of the angle when the variable
in the angle is zero.

The angle in the sin function in this equation is (pi X + 2).

When the variable 'X' is zero, the angle is  2 .

So the phase shift of this sin function is  2  (of whatever
the unit of the angle is ... 2 degrees, 2 radians, etc.)
