If x =( 5a^4) and a =( 2b^3), express x in terms of b.

x = 80 b^12

Step-by-step explanation:

given as

x =(5a^4)          1                         and a =(2b^3)         2

now if we put the value of a in eq 1, then we can write x in terms of b

therefore x= (5(2b^3)^4)

                 = (5(2^4×b^12))

                 = (5(16× b^12))

                 = 80 b^12

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
