Circle whether the point is a solution to the inequality. Show work to support the answer.y ≤ 1/3x + 4 is (-6,2) a solution?Yes/No
Answers
Answer:Explanation:
Yes
The point is a solution if it satisfies the inequality.
In this case, the inequality is y ≤ (1/3)x + 4, so replacing (x, y) = (-6, 2), we get:
y ≤ (1/3)x + 4
2 (1/3)(-6) + 4≤
2 ≤ -2 + 4
2 ≤ 2
Since 2 is equal to 2, the inequality is satisfied and (-6, 2) is a solution.

In a certain science experiment, it was required to estimate the nitrogen
content of the blood plasma of a certain colony of rats at their 37th day of age.
A sample of 9 rats was taken at random and the following data was obtained
(grams per 100cc of plasma):
0.98, 0.83, 0.99, 0.86, 0.90, 0.81, 0.94, 0.92, and 0.87.
Find the estimates for the average content and the variation in nitrogen
content in the colony.
Answers
The estimates for the average content is 0.9.
The variation in nitrogen content in the colony is 0.0036.
What is the average of a data set?
The average of a data set or the mean of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The sum of the data set is calculated as follows;
total = 0.98 + 0.83 + 0.99 + 0.86 + 0.9 + 0.81 + 0.94 + 0.92 + 0.87
total = 8.1
The estimated average of the nitrogen content = 8.1/9 = 0.9
The deviation of each data from the mean;
= (0.98 - 0.9), (0.83 - 0.9), (0.99 - 0.9), (0.86 - 0.9), (0.9 - 0.9), (0.81 - 0.9), (0.94 - 0.9), (0.92 - 0.9), (0.87 - 0.9)
= 0.08, -0.07, 0.09, -0.04, 0, -0.09, 0.04, 0.02, -0.03
The sum of the square of each data from the mean;
= (0.08)² + (-0.07)² + (0.09)² + (-0.04)² + (0.0)² + (-0.09)² + (0.04)² + (0.02)² + (-0.03)²

Mike works a total of 58 hr per week at his two jobs. He makes $7 per hour at job A and $8 per hour at job B. If his total
pay for one week is $424 before taxes, then how many hours does he work at each job?
Answers
Mike works 40 hours at job A and 18 hours at job B.
What are simultaneous equations?Simultaneous equations are two or more algebraic equations that share the same unknown variables and have the same solution for each of them. This suggests that the equations are simultaneous and have a single solution.
Given:
Mike makes $7 per hour at job A and $8 per hour at job B.
Let x be the number of hours Mike spends working at job A and y be the number of hours he spends working at job B.
Since he works a total of 58 hours per week,
x + y = 58
His total pay for one week is $424.
7x + 8y = 424
Solving both equations simultaneously we get,
From the first equation, we have, y = 58 - x
Putting the value of y in the second equation,
7x + 8(58 - x) = 424
7x + 464 - 8x = 424
8x - 7x = 464 - 424
x = 40
So, now calculate y = 58 - 40 = 18
Therefore, Mike spends 40 hours working at job A and 18 hours working at job B.

(b)
Find the heights reached by balloons 1, 2, 3 and 4.
Answers
Algebraic expression for Height of Balloon 2 = 7x and Height of Balloon 3 = x/2.
Heights reached by balloons 1, 2, 3 and 4 will be 54.73, 383.11, 27.36, 84.73 respectively.
We have the following given information as per the question
Balloon 1 reaches x m.
Balloon 2 reaches a height of 7 times balloon 1
∴ Balloon 2 reaches 7x m.
Balloon 3 reaches a height of half that of balloon 1.
∴ Balloon 3 reaches [tex] \frac{x}{2} [/tex] m.
Balloon 4 reaches a height of 30 meters more than balloon 1.
∴ Balloon 4 reaches ( x + 30 ) m.
Now As given The total height reached by all the balloons was 550 meters.
∴ Height of Balloon 1 + Height of Balloon 2 + Height of Balloon 3 + Height of Balloon 4 = 550 meter
∴ x + 7x + [tex] \frac{x}{2} [/tex] + (x + 30 ) =550
∴ 9.5x + 30 = 550
∴ 9.5x = 550 - 30
∴ 9.5x = 520
∴ x = 520/9.5
∴ x = 54.73 meter
(a) Algebraic expression to model the heights reached by balloons 2, 3 will be
Height of Balloon 2 = 7x = 7(54.73) = 383.11 meter
Height of Balloon 3 = x/2 = 54.73 / 2 = 27.36 meter
(b) The heights reached by balloons 1, 2, 3 and 4 will be as follows
Height of Balloon 1 = x = 54.73 meter.
Height of Balloon 2 = 7x = 7(54.73) = 383.11 meter
Height of Balloon 3 = x/2 = 54.73 / 2 = 27.36 meter
Height of Balloon 4 = x + 30 = 54.73 + 30 = 84.73 meter
