Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

Step-by-step explanation:

plz forgive me if my answer is wrong

Domain = looking for the very far left value and the very far right value on the x-axis, and only x-axis, so the farthest left x-axis value and the farthest right x-axis value.

Range = very bottom y-value, and very top y-value

In both cases, if the arrows extend forever then that means you could have the value of infinity.

A series of transformations maps EFGH onto its image. Determine the series of transformations involving a reflection, translatio
Annette [7]

Answer:

See below

Step-by-step explanation:

Firstly, we'll dilate EFGH by any scale factor.

<u><em>Let's find the scale factor first.</em></u>

=> Scale Factor = \frac{Side \ of \ dilated \ figure}{Side \ of \ original \ figure}

=> Scale Factor = \frac{6}{4}

=> Scale Factor = 1.5

1) Dilate the figure by a scale factor of 1.5

2) Reflect it across the origin

3) Translate (Move) 5 units down and then 10 units left.

These transformations will map EFGH onto its image.

Jada and Priya are trying to solve the equation 2/3+x=4
denis-greek [22]

Answer:

Priya is correct.  Because 2/3 is being added to x and not multiplied, then subtracting 2/3 from both sides is the correct action.

Step-by-step explanation:

Let's run through solving it that way:

2/3 + x = 4

2/3 - 2/3 + x = 4 - 2/3

0 + x = 4 - 2/3

x = 4 - 2/3

x = 10/3

Write whether each statement is true of false. Explain your reasoning.
sp2606 [1]
6 - p....p = 1.5
6 - 1.5 = 4.5
TRUE...because when u sub in 1.5 for p, the difference is 4.5, which is less then 5.

(30)(420) = 12000 - 600
12600 = 11400...incorrect
FALSE...because the product of 30 and 420 does not equal 600 less then 12000

16.3 + 11.9 < 27
28.2 < 27..incorrect
FALSE...because the sum of 16.3 and 11.9 is greater then 27
