Answer:

2102

Step-by-step explanation:

Evaluate   -x³+3x²+5x+1   when x = -12

simply substitue x = -12 into the equation

-x³+3x²+5x+1   when x = -12

= - (-12)³ + 3(-12)² + 5(-12)+1

= -(-1728) + 3(144) - 60 + 1

= 1728 + 432 - 60 +1

= 2102

Which graph shows the solution set of x-9/7x+2<=0
S_A_V [24]
For this case we have the following inequality:
 \frac{x-9}{7x+2}  \leq 0
 Solving for the numerator we have:
 x-9 \leq 0
 x  \leq 9
 Solving for the denominator we have:
 7x+2\ \textgreater \ 0
 7x\ \textgreater \ -2
 x \ \textgreater \   \frac{-2}{7}
 Therefore, the solution is given by:
 \frac{-2}{7} \ \textless \  x  \leq 9
 The graph that shows this solution is the graphic number 3.

Help pls is geometry
Burka [1]

Answer:

C) 16, 6

Step-by-step explanation:

  1. Set AB and DC equal to eachother. 4x = x + 12.
  2. Subtract x from both sides. 3x = 12
  3. Divide by 3 to get x alone. x = 4
  4. Plug this x value in the equation for AB. 4•(4) = 16
  5. We know the AD equals 6, so that will be one of the values and we now know that AB equals 16.
