The solution to function f(x) = 4 is 2 1/5.
Given that, f(x) = 5x - 7
Now, function f(x) = 4 implies that
i.e. 5x - 7 = 4
i.e. 5x = 4 + 7
i.e. 5x = 11
i.e. x = 11/5
x =2 1/5
So, option (4) is correct.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

The function is f(x)= 5x-7. The solution to f(x)=4 is when x is 11/5.
Given that,
The function is f(x)= 5x-7
A function is nothing but in mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain),where there is exactly one output for every input, and the output can be connected to its input.
f(x), where x is the input, is a common way to refer to a function. A function represented as y = f(x).
We have to find the solution to f(x)=4
Take 5x-7 in the place of f(x) because they are equal.
5x-7=4
5x=4+7
5x=11
x=11/5
Therefore, the solution x value is 11/5.

Choose the estimate closest to the length of a pen: 30cm, 160mm, or 16mm.
The estimate closest to the length of a pen is 160mm
How to estimate the closest length of a pen?Estimation is when we use approximate values in a calculation to give an approximate, predicted answer rather than an exact answer.
We can estimate some lengths and distances using approximate values for measurements.
For example, 16 cm is approximately the length of a pen.
Therefore, the estimate of a pen is 16 cm.
Since the length in cm is not in the option, we have to convert.
Hence,
1 centimetres = 10 millimetres
16 centimetres = ?
cross multiply
estimated length of a pen = 160 millimetres.
Therefore, the estimate closest to the length of a pen is 160mm

Angle sum of a triangle: [tex]< A + < B+ < C=180^o\\[/tex]
Types of Triangles: Isosceles, Equilateral, Scalene
Given AB = AC are two sides of the big triangle, then ΔABC is Isosceles.
Isosceles triangles are defined to have two equal sides and two equal angles (opposite the congruent(equal) sides).
Also, since ABC is defined as a triangle, BC is a straight line, a.k.a., it is a [tex]180^o[/tex] angle. As the image shows, the line, AD creates a right angle on one side, therefore it creates a right angle([tex]90^o[/tex]) on the other side.
Back to Isosceles Triangles, AD = AE means ΔADE is isosceles and <ADE = <AED
Using the Angle sum formula of a triangle, you can fill in <A, <B, and <C with the following:
<A=[tex]50^o[/tex]
<B=<C=y [This is because <ADE = <AED]
[tex]50^o+2y=180^o\\2y=130^o\\y=65^o[/tex]
Now, this means that <ADE=[tex]65^o[/tex] and <ADC =[tex]90^o[/tex]
<x is better seen as <EDC
<EDC+<ADE=<ADC
Since we know <ADE is 65 and <ADC is 90, we can plug in these to the formula above.
[tex]x+65^o=90^o\\x=25^o[/tex]

The range of distance between Aaron and Clara is 7<d<23.
What is the triangle?Triangles are three-sided polygons with three vertices. The angles of the triangle are formed by connecting the three sides end to end at a point. The sum of the triangle's three angles equals 180 degrees. Every triangle has three sides and three angles, which may or may not be the same. In the case of a right triangle, the sides are given special names, with the side opposite the right angle being known as the hypotenuse and the other two sides being known as the legs.The range of possible distance from Aaron to Clara:

The equation of the given function will be h=-0.096x+30.6. The mass will be 63.5 grams.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
1.) The slope of the given function will be,
Slope = (25.8 - 30.6) / (50 - 0) = -4.8/50 = -0.096
Now, substitute the values in the general linear equation,
h = -0.096x + c
30.6 = -0.096(0) + c
c = 30.6
Therefore, the equation of the given function will be h=-0.096x+30.6.
2.) Mass when the height is given as 24.5 cm, will be,
h = -0.096x + 30.6
24.5 = -0.096x + 30.6
24.5 - 30.6 = -0.096x
-6.1 = -0.096x
x = -6.1/-0.096
x = 63.5
Hence, the mass will be 63.5 grams.

Two positive integers that differ by 9 are in the ratio of 8 to 11. What is the value of the smaller of the two numbers?
The numbers are 24 and 33 so the smaller one is 24
Answer:
24 and 33 are the numbers among which 24 is the smallest.
Step-by-step explanation:
Let one positive integer be x, then another will be x - 9
Solve:
[tex]\sf \dfrac{x-9 }{x} = \dfrac{8}{11}[/tex]
cross multiply
[tex]\sf 11x-99= 8x[/tex]
collect like terms
[tex]\sf 11x-8x = 99[/tex]
simplify
[tex]\sf 3x = 99[/tex]
divide both sides by 3
[tex]\sf x = 33[/tex]
As the integer is positive, x = 33, then another will be 33 - 9 = 24.

one seventh times the absolute value of the quantity x minus 3 end quantity minus 2 equals 9
The solutions of "one seventh times the absolute values of the quantity x minus 3 minus 2 equals 9" is 80 and -74
The absolute value of the quantity x minus 3 = |x-3|
The one seventh time the absolute value of the quantity x minus 3 minus 2 equal to 9
Then the equation will become
(1/7)×|x-3|-2=9
Solve the equation
(1/7)×|x-3|-2= 9
(1/7)×|x-3|= 11
|x-3| = 11×7
|x-3|= 77
The absolute value equation will become
x-3= 77
x-3 = -77

The solution to the inequality is w ≥ 470 or w ≤ 530
How to determine the solution to the inequality?The given parameters are:
Number of words = 500
Absolute deviation = 30
Acceptable number of words = w
The absolute value inequality is represented as
|w - Number of words| ≥ Absolute deviation
So, we have
|w - 500| ≥ 30
Remove the absolute bracket
So, we have
w - 500 ≥ -30 or w - 500 ≤ 30
Add 500 to both sides of the inequality
So, we have
