Answer:

\frac{0.3x - 2.1}{3}  = 0.4  \\ 0.3x - 2.1 = 0.4 \times 3 \\ 0.3x - 2.1 = 0.12 \\ 0.3 x = 0.12 + 2.1 \\ 0.3x = 2.22 \\ x =  \frac{2.22}{0.3}  \\ x = 7.4

Answer:

\frac{0.3x - 2.1}{3}  = 0.4 \\ 0.3x - 2.1 = 0.4 \times 3 \\ 0.3x - 2.1 = 1.2 \\ 0.3x = 1.2 + 2.1 \\ 0.3x = 3.3 \\ x =  \frac{3.3}{0.3}  \\  \boxed{x = 11}

  • <u>x = 11</u> is the right answer.

A coordinate axis is drawn with a parabola pointing up that has vertex of 0,3. Determine the intervals on which the function is
mel-nik [20]

Answer:

Option (2). Increasing x > 0; decreasing x < 0

Step-by-step explanation:

Equation of the parabola having vertex (0, 3) will be,

y = (x - 0)² + 3

y = x² + 3

To check the function is increasing or decreasing in the given intervals we will find the derivative of the function,

\frac{dy}{dx}=\frac{d}{dx}(x^{2}+3)

y' = 2x

For x < 0 Or x = -1

y' = 2(-1)

  = -2 < 0

Therefore, function is decreasing in x < 0

For x > 0 Or x = 1

y' = 2(1) + 3

  = 5 > 0

Therefore, function is increasing in x > 0

Option (2) is the answer.
