The height is not linear depending on time. Then the incorrect option is D.

<h3>What is a linear equation?</h3>

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

In linear motion, the height of the object is given as,

u = √(2gh)

From the first equation on motion, we have

v = u - gt

0 = √(2gh) - gt

2h = gt²

h = gt² / 2

Thus, the height is not linear depending on time.

Then the incorrect option is D.

More about the linear equation link is given below.

Answer:

The answer is D


Step-by-step explanation:

Plug any x value for the y values of f(x) and g(x)

Let's do 0 since it is easier.

f(x)=-2(0)-4=-4

g(x)=-2(0)+2=2

So, g(x) is 6 greater than f(x).

Thus, g is most likely moved 6 units up from f.

Find the value of x that make it true
lesantik [10]

Answer:

Step-by-step explanation:

1). 10 = \frac{1+7x}{7+x}

   10(7 + x) = 1 + 7x

   70 + 10x = 7x + 1

   10x - 7x = 1 - 70

   3x = -69

   x = -23

2). 0.2 = \frac{6+2x}{12+x}

    0.2(12 + x) = 6 + 2x

    2.4 + 0.2x = 6 + 2x

    2.4 - 6 = 2x - 0.2x

    1.8x = -3.6

    x = -2

3). 0.8 = \frac{x}{x+0.5}

    0.8(x + 0.5) = x

    0.8x + 0.4 = x

    x - 0.8x = 0.4

    0.2x = 0.4

    x = 2

4). 3.5 = \frac{4+2x}{0.5-x}

    3.5(0.5 - x) = 4 + 2x

    1.75 - 3.5x = 4 + 2x

    -3.5x - 2x = 4 - 1.75

    -5.5x = 2.25

     x = -\frac{2.25}{5.5}

     x = - \frac{9}{22}

A copying machine reduces a 12 cm line to 10.5 cm

you can find the percentage by using 10.5/12 and x/100 to find x

10.5 * 100 = 1050

1050/12=87.5
