For this case we have the following inequality:

2x + 1

Subtracting 1 from both sides of the inequality we have:

2x

Dividing between 2 on both sides of the inequality:

x

Thus, the solution is given by all values of "x" less than 2.

Answer:

x

An N-scale model railroad caboose is 3 inches long. N scale is 169 feet to 1 foot.
hammer [34]

9514 1404 393

Answer:

  • c/3 = 169/12
  • 42 1/4 feet

Step-by-step explanation:

Since we want to know the actual number of feet, we can write the proportion with that in the numerator.

  \dfrac{\text{actual feet}}{\text{scale inches}}=\boxed{\dfrac{c}{3}=\dfrac{169}{12}}\\\\c=\dfrac{3\cdot169}{12}=42\frac{1}{4}\qquad\text{multiply by 3}

The real caboose is 42 1/4 feet long.

Answer:

D. The minimum y-value of g(x) approaches -3

Step-by-step explanation:

Form a table for values of x with corresponding values for f(x) and g(x)

<u>x   </u>                 <u>f(x)=3x²-3                                         g(x)=2^x -3                           </u>

-3                   =3(-3²)-3=24                                       2⁻³ -3 = -2.88

-2                    =3(-2²)-3=9                                        2⁻² -3 = -2.75

-1                     =3(-1²)-3=0                                         2⁻¹-3 = -2.5

0                      =3(0²)-3= -3                                        2⁰ -3 = -2

1                       =3(1²)-3=0                                           2¹ -3 = -1

2                      =3(2²)-3=9                                          2²- 3 = 1

3                     =3(3²)-3=24                                          2³ -3= 5

From the table above, you can see the minimum value of y in g(x)  -2.88 approaches -3
