What is 4x- 45y × 34- -43 +π³÷√9-7889²×-2.488×1/3÷14÷2+83π-3× -3399.3884-10³? answer this challenging question for 25 points

4x -1530y+7388517.774

Step-by-step explanation:

4x- 45y × 34- -43 +π³÷√9-7889²×-2.488×1/3÷14÷2+83π-3×-3399.3884-10³

= 4x- 45y × 34+43 +π³÷√9-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000

= 4x- 45y × 34+43 +31.018÷3-62236321×-2.488×1/3÷14÷2+83π-3×-3399.3884-1000

= 4x- 45y × 34+43 +10.34-62236321×-2.488×1/3÷14÷2+83π+13199.652

= 4x- 45y × 34+43 +10.34-62236321×-0.1185+260.752+13199.652

= 4x- 45y × 34+43 +10.34+7375004+260.752+13199.652

= 4x -1530y+7388517.774

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the correct answer is a.) bc< mn 5 stars if this you : )
