The slope of the line AB by joining the coordinates x and y is equal to 2.
Let the coordinates of the points A and B to form a line AB by joining them are:
A ( x₁ , y₁ ) = A ( x₁ = 50 , y₁ = 30 )
B ( x₂ , y₂ ) = B ( x₂ = 60 , y₂ = 50 )
Slope of the line by joining two points is :
= ( y₂ - y₁ ) / ( x₂ - x₁ )
Substitute the value in the formula we get,
Slope of the line
= ( 50 - 30 ) / ( 60 - 50 )
= ( 20 ) / ( 10 )
= 2 / 1
= 2
Therefore, the slope of the function y and x for line AB by joining the coordinates of A and B is equal to 2.
The given question is incomplete, I answer the question in general according to my knowledge:
If the point is at A ( x = 50 , y = 30 ) and point B is at ( x = 60 , y = 50 ) , what is the slope of the function described by y and x for line AB?

The first term of a sequence is -2, and the common difference is 6.
what are the next three terms?
The next three terms of the sequence will be 4,10,16.
What is a sequence?
A sequence is a list of numbers (or elements) that exhibits a particular pattern. For example, Olivia has been offered a job with a starting monthly salary of $1000 with an annual increment of $500. Can you calculate her monthly salary in the first three years? It will be $1000, $1500, and $2000. Observe that Olivia's salary over a number of years forms a sequence as they follow a pattern where the numbers are increasing by an amount of $500 every time.
Some of the most common examples of sequence are:
Arithmetic Sequences
A sequence in which every term is created by adding or subtracting a definite number from the preceding number is an arithmetic sequence.
Geometric Sequences
A sequence in which every term is obtained by multiplying or dividing a definite number with the preceding number is known as a geometric sequence.
Harmonic Sequences
A series of numbers is said to be in harmonic sequence if the reciprocals of all the elements of the sequence form an arithmetic sequence.
Fibonacci Numbers
Fibonacci numbers form an interesting sequence of numbers in which each element is obtained by adding two preceding elements and the sequence starts with 0 and 1. Sequence is defined as, F0 = 0 and F1 = 1 and Fₙ = Fn-1 + Fn-2
Now,
Given first term=-2
difference is =6
Therefore,
The next three terms of arithmetic sequence will be -2+6,-2+6+6,-2+6+6+6 i.e. 4,10,16.
Hence,
The next three terms of the sequence will be 4,10,16.

Answer: x=-6 y=-8
Step-by-step explanation:
For 1st equation solve for x.
3x-2y=-2
3x=-2+2y
x=[tex]\frac{-2+2y}{3}[/tex]
Then plug in the x found in 1st equation into the 2nd equation.
-7x+6y=-6

x=[tex]\frac{-2+2(-8)}{3}[/tex]
x=[tex]\frac{-2-16}{3}[/tex]
x=[tex]\frac{-18}{3}[/tex]
x=-6
Answer:
x = -6 and y = -8
Step-by-step explanation:
These two simultaneous linear equations using elimination method:
For this method to be applied, the coefficients of ‘x’ or ‘y’ in the two equations need to be the same with opposite signs.
The coefficients of ‘x’ will be focused on:
(3x - 2y = -2) Multiplied by 7
(-7x + 6y = -6) Multiplied by 3
21x - 14y = -14
-21x + 18y = -18
In the net total, it can be observed that the two ‘x’ terms will completely cancel each other out:
4y = -32
[tex]y = -\frac{32}{4}[/tex]
y = -8
Substitute this value of y in any of the equations to determine the value of x:
3x - 2(-8) = -2
3x + 16 = -2
3x = -2 - 16
3x = -18
[tex]= x =- \frac{18}{3}[/tex]

29 of the firt 42 preident of the United State were lawyer what percentage of thee preident were lawyer
To find the percentages of U.S. presidents who were lawyers, we can divide the number of presidents by the total number of presidents and then multiply by 100 to get the answer as a percentage.
Given the information, we have:
Number of presidents who were lawyers = 29
Total number of presidents = 42
So, the percentages of presidents who were lawyers is:
(29 / 42) * 100 = 69%
Therefore, 69% of the first 42 U.S. presidents were lawyers.
A percentage is a number or ratio expressed as a fraction of 100. It represents a portion of a whole and is often used to describe parts of a larger quantity in terms of 100. For example, if a student scored 80 out of 100 on a test, their score can be expressed as 80%, which means they answered 80 out of 100 questions correctly. The symbol for percentage is "%". To convert a fraction or decimal to a percentage, it is multiplied by 100.

For each graph, f(x) is the parent function and g(x) is a transformation of f(x). Use the graph to determine the equation of g(x).
The equation of g(x) when the parent function f(x) = 3^x is transformed is g(x) = 3^{x - 4} + 5.
The equation of g(x) when the parent function f(x) = 2^x is transformed is g(x) = 4(2)^{x - 3}.
The equation of g(x) when the parent function f(x) = 4^x is transformed is g(x) = -2(4)^{x + 1} + 3.
How to determine the equation of g(x) by using the graph?By critically observing the graph of the exponential function f(x) = 3^x, we can reasonably and logically deduce that f(x) is vertically translated (k) by 5 units up and horizontally translated (h) by 4 units to the right. Therefore, the equation of g(x) is given by:
g(x) = 3^{x - h} + k
g(x) = 3^{x - 4} + 5.
Based on the graph of the exponential function f(x) = 2^x, we can reasonably and logically deduce that f(x) is compressed by a scale factor (a) of 4 units and horizontally translated (h) by 3 units to the right. Therefore, the equation of g(x) is given by:
g(x) = a(b)^x - h}
g(x) = 4(2)^{x - 3}
Based on the graph of the exponential function f(x) = 4^x, we can reasonably and logically deduce that f(x) is reflected across the x-axis and expanded by a scale factor (a) of 2 units, followed by a translation of 1 units left and 3 units up:
where; a = -2, h = -1, and k = 3.

a population has µ = 30 and σ = 10. if 5 points are added to every score in the population, what are the new values for the mean and standard deviation?
If 5 points are added to every score in the population, then new values for mean is 35 and standard deviation is 10 .
If 5 points are added to every score in the population, the mean (µ) of the population will increase by 5 and the standard deviation (σ) will remain unchanged.
The new mean (µ') will be:
⇒ µ' = µ + 5 = 30 + 5 = 35
The new standard deviation (σ') will be:
⇒ σ' = σ = 10

what is the Greatest Common Factor of (48x^(2)-40x)/(56x)
Answer: the GCF of (48x^2 - 40x) / (56x) is 8x.
Step-by-step explanation:
To find the greatest common factor (GCF) of the expression (48x^2 - 40x) / (56x), we can use the following steps:
Factor the numerator: 48x^2 - 40x = 8x(6x - 5)
Identify the monomial that divides evenly into both the numerator and denominator: 8x
Divide out this monomial from both the numerator and denominator. This will simplify the fraction to (6x-5)/7
Therefore, the GCF of (48x^2 - 40x) / (56x) is 8x.

Answer:
20
Step-by-step explanation:
[tex]20^{2} = 400[/tex]
[tex]\sqrt{400} = 20[/tex]
Answer: The square root of 400 is 20.
Step-by-step explanation:
The square root of a number is the value that, when multiplied by itself, gives the original number. To find the square root of 400, you can use the long division method or an electronic calculator.
Alternatively, you can approximate the square root of 400 by finding the nearest perfect square (a number whose square root is a whole number). In this case, the perfect squares closest to 400 are 361 and 441. Since the square root of 361 is 19 and the square root of 441 is 21, you can estimate that the square root of 400 is between 19 and 21. Since 20 is halfway between 19 and 21, you can approximate the square root of 400 to be 20.

given that the current in (ma) flowing through a wire is given by: i(t) = ⎧ ⎪⎨ ⎪⎩ 0 for t < 0 6t for 0 ≤ t ≤ 5 s 30e−0.6(t−5) for t ≥ 5 s, (a) sketch i(t) versus t. (b) sketch q(t) versus t.
The given equation represents the current (i (t)) flowing through a wire in milliamps (ma) over time (t) in seconds (s).
(a) To sketch i (t) versus t, the equation i (t) is first rearranged into three separate parts; i (t) = 0 for t < 0, i (t) = 6t for 0 ≤ t ≤ 5s and i (t) = 30e−0.6(t−5) for t ≥ 5s. The graph is then plotted with the origin (0, 0) and the points (0, 0), (5, 30) and (10, 0). A line is then drawn from (0, 0) to (5, 30) and then from (5, 30) to (10, 0). The resulting plot is the graph of i (t) versus t.
(b) To sketch q (t) versus t, the integral of the equation i (t) is taken. The integral of i (t) = 0 for t < 0 is 0. The integral of i (t) = 6t for 0 ≤ t ≤ 5s is q (t) = 3t2 + C. The integral of i (t) = 30e−0.6(t−5) for t ≥ 5s is q (t) = −30e−0.6(t−5) + C. The graph is then plotted with the origin (0, 0) and the points (0, 0), (5, 75) and (10, -30). A line is then drawn from (0, 0) to (5, 75) and then from (5, 75) to (10, -30). The resulting plot is the graph of q (t) versus t.
