Answer:
The second one
Step-by-step explanation:
A linear function will always increase or decrease by the same amount:
The first one adds eight for every increase of 1 in the x value
The third one subtracts three for every increase of 1 in the x value
However,
The second one starts by adding three, and then adds 1.5 for the rest
The second table is nonlinear
Answer:
Option B:
Sammi made a mistake in Step 2 because he chose a title without knowing if the table represents the number of hours read per week.
Step-by-step explanation:
A dot plot type of a problem.
Sammi forgot to put the corresponding title for the dots such as whether those were the correspondents name or a universal label such as college students. This will make the graph have a mistake in some places. Sammi should include the label that corresponds or represents the dot.
Step-by-step explanation:
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 16 from both sides</em>
Substitute:
The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684
Divide both sides by 19:
19x/19 = 684/19
x = 36 m
Step by step explanation
<u>let x be the number of minutes and y be the total charges per month</u>
<em>A. Melissa's cell phone plan charges two cents a minute plus a $10 monthly fee. </em>
<em>y=0.02x+10</em>
<em> </em>
<em>B. Sandra's cell phone plan charges seven cents a minute. </em>
<em>y=0.07x</em>
<em />
<em>C. Holly's cell phone plan charges five cents per minute. She also receives a $5 discount each month.</em>
<em>y=0.05x-5</em>
<em />
<em> D. Alicia's cell phone plan charges six cents per minute plus a $5 monthly fee.</em>
<em>y=0.06x+5</em>
