4x + y< 2

Mathematics
1 answer:
bulgar [2K]3 years ago
5 0

The two inequalities can be rewritten as

\begin{cases}y-2\end{cases}

The solution is composed by every point below the graph of the line y=-4x+2, and above the horizontal line y=-2

To draw the line y=-4x+2 we can build a little table (only 2 points are required):

\begin{array}{c|c}x&y\\0&2\\1&-2\end{array}

So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.

To draw the line y=-2, simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.

Choose the above/below areas as specified above to solve the system.

Question 1. Which of the following is not true for the equation six times d equals twelve?
Deffense [45]
Q1. The answer is To solve, you must divide both sides by 6

The equation is:   6d = 12
<span>Multiplication is the inverse operation: TRUE -         6d = 12      d = 12/6
Checking the solution involves multiplication: TRUE -    6 * 2 = 12
The equation represents the number that gives twelve when multiplied by 6: TRUE     d is </span>the number that gives twelve when multiplied by 6<span>
To solve, you must divide both sides by 6: false


Q2. The answer is 18
</span><span>
x - the number of students

The students were divided equally among 3 chaperones: 3 chaperones per x
Each chaperone supervised 6 students: 1 chaperone per 6 students
 
3 : x = 1 : 6
x = 3 * 6 : 1
x = 18


Q3. The answer is </span><span>t is greater than or equal to five.
</span>
It will take Harlon at least five years to complete his college degree. The key word is at least. This means that it can include number 5 as well. He may need 5 years, 6 years, 7 years,... Hence, t is greater than or equal to five.


Q4. The answer is <span>1.2
</span>
<span>p over zero point three + 2 = 6
p/0.3 + 2 = 6

multiply both sides by 0.03
p + 2 * 0.3 = 6 * 0.3
p + 0.6 = 1.8
p = 1.8 - 0.6
p = 1.2


Q5. The answer is 2.

</span><span>16w = 32

Divide both sides by 16
16w/16 = 32/16
w = 2</span>

Mekhanik [1.2K]

Answer: 0.8413

Step-by-step explanation:

Given : Henry has collected data to find that the typing speeds for the students in a typing class has a normal distribution.

Mean : \mu=47

Standard deviation : \sigma= 4

Let x be the random variable that represents the typing speeds for the students.

The z-score :-

z=\dfrac{x-\mu}{\sigma}

For x= 51

z=\dfrac{51-47}{4}=1

Using the standard normal distribution table ,the probability that a randomly selected student has a typing speed of less than 51 words per minute :-

P(x

Hence, the probability that a randomly selected student has a typing speed of less than 51 words per minute = 0.8413
