A 2-column table with 4 rows. Column 1 is labeled x with entries 1, 2, 4, 5. Column 2 is labeled y with entries 15, 30, 60, 75. x y

1 15

2 30

4 60

5 75

Does this table represent a proportional relationship?

(A) No. The points are not on the same line.

(B) No. The line does not pass through the origin.

(C)No. The ordered pairs do not make equivalent ratios.

(D) Yes. The points are on a line that passes through the origin.

the answer is 5/3x+7/5y+7

answer: the answer is 127 degrees

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
