None of the above (e) is the answer. This problem can be easily solved with the formula m/x=k. Specifically for this problem, the equation would be 60/6=k. Basic division tells us that k=10, which is not one of the choices you had to choose from. Therefore, the answer is e.

If m varies directly with x, then that means that you have to find the slope. To make it easier, m = y-variable, and x = x-variable.

Because you are trying to find your constant of variation (another word for slope, rate of change, etc.), the change of y over the change of x is your equation. in other words, divide your m variable by x.

When m = 60 and x = 6, you can set it up. 60 / 6 = k; and k = 10 when solved. Since 10 is not one of the answer choices listed in your answer key, I believe that your answer is NONE OF THE ABOVE.


I hoped this helped you.

Angle x and y are complementary. Angle x is supplementary to a 128º angle.
tiny-mole [99]

Answer:

x = 52

y = 38

Step-by-step explanation:

Angle x is supplementary to a 128º angle.

Supplementary angles add to 180

x+128 = 180

Subtract 128 from each side

x+128-128 = 180-128

x =52

Angle x and y are complementary.  

Complementary angles add to 90

x+y =90

52+y =90

Subtract 52 from each side

52-52 +y = 90-52

y = 38

You plant a spruce tree that grows 4 inches per year and a hemlock tree that grows _____ inches per year. The initial heights ar
UNO [17]

<em>Complete Question:</em>

<em>You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year. </em>

<em>The initial heights are shown. </em>

Write a system of linear equations that represents this situation.

Answer:

s(x) = 8 + 4x

h(x) = 14 + 6x

Step-by-step explanation:

Given

Spruce Tree (s):

Initial\ Height = 8

Growth = 4 (yearly)

Hemlock Tree (h):

Initial\ Height = 14

Growth = 6 (yearly)

Required

Represent as system of linear equations

Let the number of years be x.

In both cases, the equation can be formed using:

Equation = Initial\ Height + Growth * x

For Spruce Tree (s):

s(x) = 8 + 4 * x

s(x) = 8 + 4x

For Hemlock Tree (h):

h(x) = 14 + 6 * x

h(x) = 14 + 6x

<em>Hence, the equations are </em>s(x) = 8 + 4x<em> and </em>h(x) = 14 + 6x<em></em>
