    Four order pairs are ( 2, 5 ), ( 4, 8 ), ( 6, 11 ), ( 0, 2). All those I cited are whole numbers so that should help plot them, and from there get a ruler or straight edge and align all the dots to create the line for the equation. The equation you gave was the standard form which was created out of the formula to find a equation it's y = mx + b, there could be small variations made. How I know it's proportional is because all linear equations are. But if that's not enough I also know since there's a ratio or pattern that it follows and doesn't stray from. In more depth, porportional relationship is a ratio between y and x which is the same thing everytime shown if simplified.

Oksi-84 [34.3K]

Answer:

x = 10

Step-by-step explanation:

Okay, let's solve :)

So first we have to distribute on the left side(it doesn't matter which side FYI)

When we do, we have :

10x + 30 = -4(-5-2x)

Now we distribute on the right side! Remember, negative * negative = positive.

10x + 30 = 20 + 8x + 3x

Let's simplify on the right side to

10x + 30 = 20 + 11x

Now, let's subtract 10x on both sides to get

x + 20 = 30(i simply flipped the equation)

Subtract 20 on both sides to get!

x = 10!

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.
