Let x, y and z be non-zero numbers. If x: y = 3 : 1 and y: z = 4:3, find (x + z) : (x + y). Please help me to solve this question with steps, thanks!orz

 15 : 16

Step-by-step explanation:

x : y              y : z

3 : 1              4 : 3

Find the LCM for both y's.  LCM = 4

     x : y                        y : z

3(4) : 1(4)                      4 : 3

 12 :  4                         4 : 3

-->    x : y : z = 12 : 4 : 3

 (x + z) : (x + y)

12 + 3 : 12 + 4

   15   :     16

i can you with this question sweetie!

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
