Given:
The inequality is
[tex]x+19\leq 23[/tex]
To find:
The value of x and then graph on the number line.
Solution:
We have,
[tex]x+19\leq 23[/tex]
Subtracting 19 from both sides, we get
[tex]x+19-19\leq 23-19[/tex]
[tex]x\leq 4[/tex]
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.

What is an exponential function?
An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula
f(x) = eˣ
11 - 9 = 2 = 2¹
15 - 11 = 4 = 2²
23 - 15 = 8 = 2³
39 - 23 = 16 = 2⁴
Therefore, we can deduce that the parent function for this function represented in the table is an exponential function.
If function f was translated up to 5 units, then f(x) values would be increased by 5. Also, a point in the table for the transformed function is equal to (1, 4).

It takes 45 min for Faucet A to fill a tank, and it takes Faucet B 63 min. How many minutes will it take the two faucets to fill the tank together?
Answers
Answer:
the total minutes taken together is 26.25 minutes
Step-by-step explanation:
The computation of the number of minutes that required to fill the tank together is shown below:
[tex]\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25[/tex]minutes
Hence, the total minutes taken together is 26.25 minutes

1.how do you make your estimate on different quantities like time,angle, temperature and rate?
2.was your estimate as good as the actual measurement?
3.what difficulties did you encounter in making your estimate?
Answers
Answer:
See Explanation
Step-by-step explanation:
Note: This question is more of an opinion. The answers I will provide will be base on my personal encounters with the given quantities.
Solving (1): Estimates of the given quantities
To make estimates, you employ the use of measuring device of each quantity.
For instance:
Time ----- Clock
Angle ---- Protractor
Temperature ---- Thermometer
Rate ---- This solely depend on the rate that is being measured (e.g. speedometer for speed)
Solving (2): Estimate and Actual measurement
In my case, the answer is yes because I have mastered the use of each device.
Solving (3): Difficulties
Some of the difficulties that may be encountered when taking estimates are:
- Using the wrong tools
The absence of the right measuring devices or alternate devices will definitely not give an accurate result
(e.g it will be difficult to measure an angle with a ruler)
- Unstable environments
Stable environments give accurate results.
(e.g It may be difficult to measure the speed of a car when it does not move at a constant speed; In this case, you may opt for the instantaneous speed)
- Poorly calibrated or un-calibrated devices
When a device is not calibrated properly, the device will give wrong measurements.
