For the data in the table does y vary directly with x? If it does write an equation for the direct variation X Y
16 4
32 16
48 36

A)yes; y=2x
B)yes; y=1/4x
C)yes; y=1/8x
D) No; y does not vary directly with x

Answers

Answer 1
Answer:

Answer:

D) No; y does not vary directly with x.

Step-by-step explanation:

We can affirm that y varies directly with x, that is, that y is directly proportional to x if they fulfill the following condition.

y/x = k

where,

k is a constant number

We have 3 ordered pairs:

a) (16, 4)

b) (32, 16)

c) (48, 36)

If we perform y/x for each ordered pair,

a) 4/16 = 0.25

b) 16/32 = 0.50

c) 36/48 = 0.75

Since y/x is not constant, y does not vary directly with x.

A line passes through the point (-3,-4) and its y-intercept is (0,9). what is the equation of the line that is parallel to the first line and passes through the point (3,-7)?a. y=3/5x+2
b. y=5/3x+2
c. y=-5/3x-2
d. y=5/3x-2

Answers

You have a mistake in your question... y-intercept must be ( 0, -9 ), because with coordinates ( 0, 9 ) there is no answer.
The line equation of the 1st line: 
-4 = -3m - 9
3 m = - 9 + 4
3 m = -5
m = - 5/3
If the 2nd line is parallel to this one m-value is also -5/3.
-7 = - 5/3 · 3 + b
- 7 = - 5 + b
b = - 2
Answer: C ) y = - 5/3 x - 2

A peregrine falcon can fly 322 km/h h. How many meters can the falcon fly.

Answers


That depends on how many fish or mice he ate yesterday, how well
he slept last night, and where he really wants to be.

From the information given in the question, the only things we can
really say for sure is that if he maintains his top speed, he will fly
322,000 meters for every hour that he keeps it up, and that he will
be one scrawny, exhausted bird when it's all over.
