So this is how we solve this question by cancelling x value in both equations for obtaining y and then substituting y in equation to get x

3x = 2y. Is this equation a linear or non-linear relation? How do you know?
viktelen [127]

Answer:

  • linear equation
  • all variables are to the first power

Step-by-step explanation:

"Linear equation" is another way to say "first-degree equation." That is, the equation involves constants and variables to the first degree only. No term contains any product or ratio of variables.

A term is first degree when the sum of all of the exponents of the variables is 1, and all exponents are positive integers. That is, the only allowed exponent of the single variable in a term is 1.

Here, the term on the left side of the equal sign has x to the first power. The term on the right side of the equal sign has y to the first power. Both are linear terms, so this is a linear equation.

subtract 6-5.5 to get .5

and then divide .5/6 to get 0.0833

then multiply that quotient by 100 to get percentage

PLZ HELP WILL GIVE 50 POINTS - QUADRATIC APPLICATIONS
Contact [7]

Answer:

The bird will be at a ground distance of 10.04 units away.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

f(x) = ax^{2} + bx + c

It's vertex is the point (x_{v}, y_{v})

In which

x_{v} = -\frac{b}{2a}

y_{v} = -\frac{\Delta}{4a}

Where

\Delta = b^2-4ac

If a<0, the vertex is a maximum point, that is, the maximum value happens at x_{v}, and it's value is y_{v}.

Equation for the height:

The height of the bird after x seconds is given by:

h(x) = -0.114x^2 + 2.29x + 3.5

Which is a quadratic equation with a = -0.114, b = 2.29, c = 3.5.

When the bird is at its highest?

Quadratic equation with a < 0, and thus, at the vertex. The ground distance is the x-value of the vertex. Thus

x_{v} = -\frac{b}{2a} = -\frac{2.29}{2(-0.114)} = 10.04

The bird will be at a ground distance of 10.04 units away.
