Answer:

<em>No values of x can make f(x)=6</em>

Step-by-step explanation:

Equation with Absolute Value

The absolute value of a number is always positive. That condition must be met when solving equations. Any condition that goes against the rule, must be discarded and not part of the solution.

The function provided in the question is:

f(x) = -0.5|2x + 2| + 1

We need to find the value(s) of x that make:

f(x)=6

It needs to solve the equation:

-0.5|2x + 2| + 1=6

Subtracting 1:

-0.5|2x + 2| =6-1=5

Dividing by -0.5:

|2x + 2| =5/(-0.5)=-10

We reach to this equation to solve:

|2x + 2| =-10

As stated above, the absolute value is always positive, and the equation forces the absolute value to be negative. There is no possible value of x that makes the absolute value negative, thus:

No values of x can make f(x)=6

A lighthouse is located at (1, 2) in a coordinate system measured in miles. a sailboat starts at (–7, 8) and sails in a positive
schepotkina [342]

The system of equations that can be used to determine whether the boat comes within 5 miles of the lighthouse is:

  • y = (2/7)(x - 2)^2 - 6
  • (x - 1)^2 + (y - 2)^2 = 5^2

<h3>What are equations?</h3>
  • The equation is described as the state of being equal and is commonly represented as a math expression with equal values on either side, or it refers to an issue in which many factors must be considered.
  • 2+2 = 3+1 is an example of an equation.

To find the system of equations that can be used to determine whether the boat comes within 5 miles of the lighthouse:

The vertex form of a quadratic function is given by: f(x) = a(x - h)^2 + k

Where (h, k) is the vertex of the parabola, a is constant.

For the sailboat we have vertex: (h, k) = (2, -6) and one point: (-7, 8) that is f(-7) = 8.

  • f(x) = a(x - 2)^2 - 6

We will find a using f(-7) = 8:

  • f(-7) = a(-7-2)^2 - 6
  • f(-7) = 49a - 6
  • 49a - 6 = 8
  • 49a = 14
  • a = 14/49
  • a = 2/7

The quadratic function for the sailboat is given by:

  • f(x) = (2/7)(x - 2)^2 - 6 or y = (2/7)(x - 2)^2 - 6

The equation for a circle with a radius of 5 and center (1, 2) is:

  • (x - 1)^2 + (y - 2)^2 = 5^2

Therefore, the system of equations that can be used to determine whether the boat comes within 5 miles of the lighthouse is:

  • y = (2/7)(x - 2)^2 - 6
  • (x - 1)^2 + (y - 2)^2 = 5^2
