Evaluate the expression when d = 20 and v = 19 20v + 12d - 6v

506

Step-by-step explanation:

First what you would do is replace the v in 20v with 19 like so 20(19) and that would give you 380. Next you would replace the d in 12d with 12(20) and that would give you 240. Then replace the v in -6v with -6(19) and that would give you -114. Add them together and you get 506. The reason why -6x19= -114 is that a negitive times a positive equals a negitive. Or

20v+12d-6v

20(19)+12(20)-6(19)

380+12(20)-6(19)

380+240-6(19)

380+240-114

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

connie < felicia < stew

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
