Choose the table that represents g(x) = −2⋅f(x) when f(x) = x + 4
fomenos

Answer:

  x g(x)

  1 −10

  2 −12

  3 −14

Step-by-step explanation:

Substitute the values and do the arithmetic.

Table values for x are 1, 2, 3. We only need to find g(1) to determine which table is the correct choice.

  f(1) = 1 +4 = 5 . . . . . . . . . put 1 where x is and do the arithmetic

 g(1) = -2·f(1) = -2·5 = -10 . . . . . matches the 3rd choice

x - price of a video tape

y - price of a DVD

\left\{\begin{array}{ccc}2x+3y=134\\x+5y=179&|\text{subtract 5y from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=134\\x=179-5y&|\text{substitute to the first equation}\end{array}\right\\\\2(179-5y)+3y=134\qquad\text{use distributive property}\\\\(2)(179)+(2)(-5y)+3y=134\\\\358-10y+3y=134\qquad\text{subtract 358 from both sides}\\\\-7y=-224\qquad\text{divide both sides by (-7)}\\\\\boxed{y=32}\\\\\text{Put the value of y to the second equation}\\\\x=179-5(32)\\\\x=179-160\\\\\boxed{x=19}

GalinKa [24]

Answer:

D. \frac{79}{6}

Step-by-step explanation:

\bigg(  \frac{7}{2} -  \frac{1}{3}  \bigg).( - 2)^{2}  +  \frac{1}{2}  \\  \\  =   \bigg(  \frac{7 \times 3 - 1 \times 2}{2 \times 3}   \bigg).4  +  \frac{1}{2}  \\  \\  = \bigg(  \frac{21 - 2}{6}   \bigg).4  +  \frac{1}{2}  \\  \\  =  \frac{19}{6}    \times 4  +  \frac{1}{2}  \\  \\  = \frac{19}{3}    \times 2  +  \frac{1}{2}  \\  \\  = \frac{38}{3}   +  \frac{1}{2}  \\  \\  = \frac{38 \times 2 + 1 \times 3}{3 \times 2}   \\  \\  = \frac{76 + 3}{6}   \\  \\  = \frac{79}{6}
