Answer:

controlled experiment

Step-by-step explanation:

Controlled experiment is a type of experiment in which except for only one variable, everything is kept constant.

The common type of the controlled experiment compares the control group against the experimental group. All the variables are identical between two groups except factor which is being tested.

Big advantage of the controlled experiment is that one can eliminate much of uncertainty about the results.

Solution:

2/x     +  y/4     =    3/2

Let's solve for y.

2/ x    +   y/ 4    =     3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8    =     6x

Step 2: Add -8 to both sides.

xy    +    8    +    −   8    =    6x    +    −8

xy    =   6x   −    8

Step 3: Divide both sides by x.

xy/x     =       6x    -    8/x

Answer   =====>  y   =    6x     -   8/x




When Graph:  

y     =     6    -   8/x

x- Intercepts Points:

4/3,    and       0




Equation====>  2:

Let's solve for x.

2/ x      +    y/ 4     =      3/ 2

Step 1: Multiply both sides by 4x.

xy     +    8     =    6x

Step 2: Add -6x to both sides.

xy    +    8    +    − 6x    =     6x     +     −  6x

xy    −     6x    +    8    =    0

Step 3: Add -8 to both sides.

xy     −     6x    +    8    +    −    8      =     0    +       −8

xy     −    6x      =   −8

Step 4: Factor out variable x.

x(y   −   6)    =    −8

Step 5: Divide both sides by y-6.

x( y   -    6 )/y   -  6       =        -8/ y    -   6

Answer  ======>      x     =       -8/y    -   6







Hope that helps!!!!                                  : )

What is the first step in constructing an incenter to triangle xyz?
Marizza181 [45]

The first step is constructing an angle bisector for one of the angles of the triangle.

We have to find the first step for the constructing an inscribed circle

<h3>What is the incenter triangle?</h3>

The incenter of a triangle is the point from which the distances to the sides are equal, in this point we can start to construct the inscribed circle in the triangle because the incenter would also be the center of the circumference.

Therefore the first step in constructing an angle bisector for one of the angles of the triangle.

A rock is dropped off a 500-foot cliff. After 1 second the rock is traveling 32 feet per second then after 4 seconds the rock st
kozerog [31]

Answer:

<u>A. The equation describing the relationship between speed and time is:</u>

<u>s = 32t</u>

<u>Ordered pairs of the form (speed, time) are:</u>

<u>(32, 1)</u>

<u>(64, 2)</u>

<u>(96, 3)</u>

<u>(128, 4)</u>

<u>B. </u>

<u>Using s = 32t, we have:</u>

<u>s = 32 * 5 = 160 feet per second</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Height of the cliff = 500 feet

Speed after one second = 32 feet per second

Speed after four seconds = 128 feet per second

2. Assume the relationship between time, t, and speed, s, is linear and write an equation describing the relationship. Use ordered pairs of the form (speed, time)

The equation describing the relationship between speed and time is:

s = 32t

Ordered pairs of the form (speed, time) are:

(32, 1)

(64, 2)

(96, 3)

(128, 4)

3.  Use the equation to determine the speed of the rock 5 seconds after is dropped.

s = 32t

s = 32 * 5 = 160 feet per second
