Line l and line m are straight lines. What is the measure of angle y? PLEASE HELP ! Line l intersects line m to form 4 angles. Clockwise, from the top, the angles are: y, x, z, 43 degrees.
43°
47°
137°
147°

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

the answer is c hope it

step-by-step explanation:

c - they will have the same distribution
