Answer: D- f(x) - g(x) = -2x^{3} + 2x^{1/2}

Step-by-step explanation:

f(x) - g(x) = (x^{1/2} - x) - (2x^{3} - x^{1/2} - x)

f(x) - g(x) = x^{1/2} - x - 2x^{3} + x^{1/2} + x - distribute negative sign

f(x) - g(x) = -2x^{3} + 2x^{1/2} - combine like terms ( -x & +x cancel out)

Morgarella [4.7K]

Answer:

( 7 , 4 )

given:

  • 4x + 10y = 68
  • 4x - y = 24

make y the subject in equation 2:

4x - y = 24

-y = 24 - 4x

y = 4x - 24

insert this in equation 1:

4x + 10y = 68

4x + 10(4x - 24) = 68

4x + 40x - 240 = 68

44x = 68 + 240

44x = 308

x = 7

solve for y:

y = 4x - 24

y = 4(7) - 24

y = 4

For this case we have the following solution.
 x = gallons of water to be added
 For the 10% solution we have:
 0.1 * 8 = 0.8
 Then, for 5% we have:
 (0.8 / x + 8) = 0.05
 Rewriting:
 (0.8 / x + 8) = (5/100)
 Answer:
 An equation can be used to find x, the humber of gallons of water he should add is:
 (0.8 / x + 8) = (5/100)

Answer:  " b = 3 ⅕ ; or, write as: 3.2  .
_____________________________________
Given:  "A = (1/2) * b * h " ;

 ↔  A = (b * h) / 2 

2A = (b*h) ;

2A/ h = b ;

↔ b = (2A) / h ;

Given A = 48 ;  and h = 30 ; Plug in these values; and solve for "b" ; 

→ b = (2*48) / 30 ; 

        = 96/30 ; 

        = (96÷6) / (30÷6) ;

→ b = 16/5 ;  = 3 <span>⅕ ; or, write as: 3.2 .
