smaller number = y
larger number = x
x - y = 69
4y = x + 3
you can solve this using substitution
x = 69 + y
(isolating one of the variables)
4y = 69 + y + 3
(substituting 69 + y for x into the other equation)
4y = 72 + y
3y = 72
y = 24
(simplify)
x - 24 = 69
x = 93
(substituting 24 into one of the original equations)

assuming I = E(R + r), prove that I/I = R/E + r/E
If we assume that I = E(R + r), then I/I = R/E + r/E.
The inverse of a value of a number is known as the reciprocal of the number. The reciprocal can be found out by replacing the numerator with the denominator and vice versa. For example, reciprocal of a number x will be 1/x and vice versa.
Here, we are given that I = E/(R + r)
Taking reciprocals of both sides we get-
Reciprocal of I will be- 1/I
Reciprocal of E/(R + r) will be- (R + r)/ E
Thus,
1/I = (R + r)/ E
Simplifying the equation further, we get-
1/I = R/E + r/E
Hence, proved

Compare the steepness of the following functions. How does F3 compare to F1
Answer:
Function 3 is less steep.
Step-by-step explanation:
The steepness of a linear function is determined by its coefficient of x.
Since the coefficient of x in [tex]f_3(x)[/tex], 0.5, is smaller than that of [tex]f_1(x)[/tex], 2, function 3 is less steep than function 1.
Significance of the coefficient of x
We can think of the function as an equation of a line in the slope-intercept form. That is, y= mx +c, where m is the slope and c is the y-intercept.
Steepness and value of x
The larger the numerical value of m, the steeper the line is.
Significance of the sign of x
The sign (positive or negative) of m tells us the direction in which the line is sloping towards. A positive m value gives us a line sloping upwards from left to right, while a negative m value gives us a line that is sloping downwards from left to right.

https://brainly.com/question/13359759An observation deck extends 456 feet out above a valley. The deck sits 406 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h=-161 +406. How long will it take for the object to be 6 feet above the valley floor?
We need to know the relation between height, time to solve this problem. The time taken by the object to be 6 feet above the valley floor is 25 seconds.
The distance an object falls is proportional to the time it took to fall because of gravitational force. Here we have been given an equation that shows us the relation between height of the object and the time taken to reach that height. We know that the initial height of the object is 406 feet, if we substitute the initial height in the equation we get time to be zero which shows us that this is the initial height. We need to find out the time taken by the object to be 6 feet above the valley floor.
h= -16t+406
6=-16t+406
-400=-16t
t=400/16=25 seconds
Therefore the time taken by the object to be at a height 6 feet above the valley floor is 25 seconds.

Mr. McDowell bought a block of fudge that weighed 7/10 of a pound. He cut the fudge into 7 equal pieces. What was the weight of each piece of fudge?
Answer: 1/10 of a pound
Step-by-step explanation:
The total weight was 7/10 of a pound. Cutting the fudge into 7 pieces implies dividing the fudge by 7.
7 is the same as 7/1.
When dividing fractions, we can multiply by the reciprocal. Essentially, we just flip the second number.
[tex]\frac{7}{10}/7 =\frac{7}{10} / \frac{7}{1} =\frac{7}{10} *\frac{1}{7}[/tex]
We can multiply this out to 7/70 and then simplify to 1/10,
or we could first cross simplify by dividing the 7s out of the numerator and denominator before multiplying. Either way, your answer ends up being 1/10 of a pound.
