solve the system of equations using a matrix. x+3y=11 4x-y=31
Answer:
[tex] \sf \: x=8 and y=1[/tex]
Step-by-step explanation:
Let's solve your system by elimination.
x+3y=11;4x−y=31
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x+3y=11)
1(4x−y=31)
Becomes:
−4x−12y=−44
4x−y=31
Add these equations to eliminate x:
−13y=−13
Then solve−13y=−13for y:
−13y=−13
−13y/−13=−13/−13
(Divide both sides by -13)
y=1
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
x+3y=11
Substitute1foryinx+3y=11:
x+(3)(1)=11
x+3=11(Simplify both sides of the equation)
x+3+−3=11+−3(Add -3 to both sides)
x=8

Construct a true table. Use tea for true enough for falls
Truth Table is used to perform logical operations in Maths. These operations comprise boolean algebra or boolean functions. It is basically used to check whether the propositional expression is true or false, as per the input values. This is based on boolean algebra.
A truth table is a breakdown of a logic function by listing all possible values the function can attain. Such a table typically contains several rows and columns, with the top row representing the logical variables and combinations, in increasing complexity leading up to the final function.
Here we construct truth table for And operation -
see attachment below -
So because we don't have statements on either side of the "and" symbol that are both true, the statment ~p∧q is false. So ~p∧q=F. Now that we know the truth value of everything in the parintheses (~p∧q), we can join this statement with ∨p to give us the final statement (~p∧q)∨p.

Write in point-slope form an equation of the line through each pair of points. (1,9) and (6,2)
The equation of the line in point-slope form, which passes through the pair of points located at (1 , 9) and (6 , 2), is y - 9 = -7/5(x - 1).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (1 , 9) and (6 , 2).
m = (y2 - y1)/(x2 - x1)
m = (2 - 9)/(6 - 1)
m = -7/5
Using the point slope form, plug in the values of the slope and one point to set up the equation.
(y - y1) = m(x - x1)
where m = -7/5 and (x1 , y1) = (1 , 9)
(y - 9) = -7/5(x - 1)
y - 9 = -7/5(x - 1)

IF AB = 7, AD = 25 and CD = 10, find BC
The measure of the length of BC from the expression is 8
Addition postulateThe segment addition postulate in geometry is the axiom which states that a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments.
Given the following segments
AB = 7
AD = 25 and:
CD = 10
Using the addition postulate below:
AB+BC+CD = AD
Substitute the given parameters
7+BC+10 = 25
17+BC = 25
Subtract 17 from both sides
17+BC-17 = 25 - 17
BC = 8
Hence the measure of the length of BC from the expression is 8

Simplify by combining like terms. 7s-s
The simplification by combining like terms of 7s -s is 6s.
According to the given question.
We have an expression 7s - s.
As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression
7s - s.
Here 7s and s both are the like terms.
So, we subtract coeffcients of s to simplify the given expression.
Therefore, the simplification of the expression 7s - s is given by
7s - s

Y=3x + 1 and 5x = y + 3
How to solve this type of simultaneous equation?
Answer:
(2, 7 )
Step-by-step explanation:
y = 3x + 1 → (1)
5x = y + 3 → (2)
substitute y = 3x + 1 into (2)
5x = 3x + 1 + 3
5x = 3x + 4 ( subtract 3x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
substitute x = 2 into (1)
y = 3(2) + 1 = 6 + 1 = 7
solution is (2, 7 )

Find the geometric mean between pair of numbers.
3 √2/7 and 5√2/7
The geometric mean between pair of numbers 3√2/7 and 5√2/7 is 0.78.
The geometric mean is the average or mean value that signifies the central tendency of a set of numbers. This is obtained by finding the product of their values.
Geometric mean (GM) is calculated as:
GM = [tex]\sqrt{x y}[/tex]
where x and y are the given two values.
According to the given condition, x = [tex]\frac{3\sqrt{2} }{7}[/tex] and y = [tex]\frac{5\sqrt{2} }{7}[/tex]
Substituting these values in the equation above,
∴GM = [tex]\sqrt{\frac{3\sqrt{2} }{7} \frac{5\sqrt{2} }{7} }[/tex]
= [tex]\sqrt{\frac{30}{49} }[/tex]
= 0.78.
Thus, the geometric mean between the given two numbers is 0.78.

The next three terms of the sequence are 84.375, 63.28, 47.46
What are the next three terms?In order to determine the next three terms, the relationship between the numbers have to be determined.
When examined, it can be seen that the next number is 75% of the previous number
150 / 200 = 75%
112.50 / 150 = 75%
The next number would be 75% of 112.50 = 112.50 x 0.75 = 84.375
The second number would be 75% of 84.375 = 0.75 x 84.375 = 63.28

How far is the third fret from the first fret?
The required distance between the third and first fret would be 64.390 mm.
What are Arithmetic functions?Arithmetic functions are defined as adding, subtracting, dividing, and multiplying built-in functions.
- Subtraction operation: calculates the difference between the right-hand and left-hand operands.
for example 4 -2 = 2
+ Addition operation: on either side of the operator, additional significances are added.
For example 4 + 2 = 6
We have been given that the distance between the first and second frets is 33.641 mm.
The distance between the second and third frets is 31.749 mm.
So the distance between the third and first fret will be:
⇒ 33.641 + 31.749
