lisa evaluated the expressions 2x and x^2 for x=2 and found that both epressions were equal to 4. lisa concluded that 2x and x^2 are equivalent expressions. How could you show lisa that she is incorrect?
190 points
Answer:
Choose another number.
Step-by-step explanation
We could take x=3 and evaluate, for the first expression we would have
[tex]2x=2\cdot3=6[/tex]
and for the secod expression we would have
[tex]x^2=3^2=9[/tex]
For this choosen x, we would have
[tex]2x=6\neq9=x^2[/tex]
which would show lisa that she is incorrect.
The table shows the amount of money LaTasha charges customers to mow their lawns. The table represents a linear function.
Time (h) : 0, 1/2, 1, 1 1/2, 2
Cost ($) : 10, 14, 18, 22, 26
What does the initial value mean for this function?
A) LaTasha earns $18 for 1 hour of work.
B) LaTasha charges $10 before she begins mowing.
C) LaTasha does not charge her customers unless she has mowed for at least a half hour.
D) LaTasha charges $8.00 an hour to mow lawns.
Answer:
B) LaTasha charges $10 before she begins mowing.
Step-by-step explanation:
Latasha charges $10 before she begins mowing. From the linear function if you compare the relationship between time(hours) and cost($), you will notice that LaTasha charges $4 for 1/2 hour of mowing.
The first value shows LaTasha charges $10 before mowing. The hour value was 0 but yet her cost was $10 . The second value for time was 1/2 hour and the initial cost of $10 was added to the actual half hour she worked which is $4. After adding her initial cost of $10 , adding $4 dollar for every 1/2 hour gives your her cost in dollar. Example $10 + $4 = $ 14 , The next one she worked 1 hour which is $8 + 10 = $18 and so on
The time value increases by half hour and the cost increases by $4 . You can conclude that LaTasha charges $4 for every 1/2 hour she mow.

Step-by-step explanation:
The 50th term of 4,7,10,13,16
Final answer:
The 50th term of the arithmetic sequence is found by using the formula for the nth term of an arithmetic sequence. The 50th term is 151, considering the common difference of 3 between consecutive terms in the sequence.
Explanation:
To find the 50th term of the given arithmetic sequence 4, 7, 10, 13, 16, we first need to determine the common difference (d). The sequence increases by 3 with each term, so the common difference is 3.
The nth term of an arithmetic sequence can be found using the formula a_n = a_1 + (n-1)d, where a_1 is the first term and n is the term number. Plugging in the values for the 50th term:
a_1 = 4 (first term)
d = 3 (common difference)
n = 50 (term number)
Now, compute the 50th term:
a_50 = 4 + (50-1)×3
a_50 = 4 + 49×3
a_50 = 4 + 147
a_50 = 151
Therefore, the 50th term of this arithmetic sequence is 151.
which is shorter 3/6 of a minute or 4/6 of an hour
From the question itself, it might be clear that because a minute is so much shorter than an hour (a minute is only 1/60th of an hour, because there are 60 minutes in each hour), 3/6 of a minute will be shorter than 4/6 of an hour.
But, if you wanted to calculate this the long way, you can.
To compare these two you can convert them to a unit of time that they have in common - for example, minutes.
In the first fraction, you can reduce 3/6 down to 1/2 - you probably already know that 1/2 is the same as half a minute.
Then you can multiply fractions to find out how many minutes are in 4/6 of an hour.
4/6 can also be reduced down to 2/3. You also know that there are 60 minutes in an hour.
(2/3 / 1 hr) x (1 hr/60 min) = (2/3) x 60 = 120/3 = 40 min
40 min is of course bigger than half a minute! So 3/6 of a minute is shorter.

At an airport,there are a total of 1,160 seats in the waiting areas. There are 8 separate, same size, waiting areas. How many seats are in each waiting area
Final answer:
To find out how many seats are in each waiting area, divide the total number of seats by the number of waiting areas. In this case, there are 1,160 seats and 8 waiting areas. So, the number of seats in each waiting area is 145.
Explanation:
To find out how many seats are in each waiting area, you need to divide the total number of seats by the number of waiting areas. In this case, there are 1,160 seats and 8 waiting areas.
So, to find the number of seats in each waiting area, divide 1,160 by 8.
1,160 ÷ 8 = 145
Therefore, there are 145 seats in each waiting area.
The formula C=5/9 (F-32) can be used to convert a temperature from degress Fahrenheit to degress Celsius.
The formula C=5/9 (F-32) converts degrees Fahrenheit to degrees Celsius. A 40.0°F decrease in Fahrenheit is equivalent to a 22.2°C decrease in Celsius. The Celsius scale is also known as 'centigrade' due to the 100-degree interval between the freezing and boiling points of water.
Explanation:The formula C=5/9 (F-32) is used to convert temperatures from degrees Fahrenheit (F) to degrees Celsius (C). To demonstrate a temperature conversion with a 40.0°F decrease, if the original temperature is T°F, the new temperature in Fahrenheit after the decrease would be (T-40)°F. The corresponding decrease in Celsius is (5/9) × 40°C, as each Fahrenheit degree is equivalent to 5/9 of a Celsius degree. To show this in a formula: ∆C = 5/9 (∆F).
On a warm day with a temperature of 88°F, the conversion to Celsius is computed as follows: T°C = 5/9 × (88°F - 32) = 5/9 × 56 = 311.1°C after rounding to the nearest tenth. The Celsius scale is sometimes referred to as centigrade because it is based on 100, from the Latin centum meaning 'hundred', referring to the 100-degree interval between the freezing and boiling points of water.
An example of converting Fahrenheit to Celsius and Kelvin is the case of a student with a temperature of 103.5°F. Using the conversion formula, the Celsius temperature would be C = 5/9 × (103.5°F - 32) = 39.7°C, and the Kelvin temperature would be K = 39.7°C + 273.15 = 312.85 K.

What is distributive property?
The distributive property is the property that expresses the distributive law of algebraic multiplication. Similarly, in polynomial expression we can use the distributive property, for example, we can write a(c+b) in the form of (ac+bc).
It is given that:
Drinks: 57 drinks for $2 each Pizza: 26 slices for $2 each Candy: 55 candy bars for $1 each Peanuts
2(57 + 26) + 1(55 + 31)
a(b + c) = ab + ac
Thus, he is using the distributive property option (B) distributive is correct if 57 drinks for $2 each Pizza: 26 slices for $2 for each Candy.

Your heart beats 240 times in 4 minutes. How many times does your heart beat each minute?
To find out how many times your heart beats per minute, divide the total number of beats by the number of minutes. In this case, 240 beats in 4 minutes results in a heart rate of 60 beats per minute.
If your heart beats 240 times in 4 minutes, you can find out how many times it beats per minute by dividing the total beats by the total minutes. So, you would divide 240 beats by 4 minutes to calculate the heart rate in beats per minute (BPM).
The calculation would look like this:
240 beats \/ 4 minutes = 60 beats per minute.
Therefore, your heart beats 60 times each minute. It's interesting to note that the average heart rate is between 60 to 100 BPM for resting adults. If your heart beats 75 times per minute, it's considered within the average range.
Knowing your heart rate can be important for monitoring your fitness levels and overall health, especially during activities like exercising where your heart rate increases.
