Please help explanation if possible

Since y varies directly with x, we know that a multiplier of k will be multiplied by x.

y = kx

In order to use this equation we need to know the value of k.  That is why they gave us known values of x & y.

"when y = –51, x = 3"

Plug these values into our equation and solve for k.

–51 = k(3)

–51/3 = k   Divide both sides by 3

k = –17  Simplify

Now that we know k our equation from here on is:

y = –17x

Now we can use this equation to solve y if x = 2 by plugging in 2 for x.

y = –17(2)

y = –34  FINAL ANSWER

the y is -29 when the x is 2 in this

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

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
