Answers
The solution to the system of equations is x = 7 and y = -3
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
5x + 2y = 29
5x - 2y = 41
Add both equations
So, we have
10x = 70
Divide the equation by 10
So, we have
x = 7
Substitute x = 7 in 5x - 2y = 41
5 x 7 - 2y = 41
This gives
35 - 2y - 41
Evaluate
2y = -6
Divide by 2
y = -3
Hence, the solution to the system of equations is x = 7 and y = -3

How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
2x + 12y = −17
3x + 2y = 7
Multiply through 3x + 2y = 7 by 6
So, we have
18x + 12y = 42
Subtract the equation 2x + 12y = −17 from 18x + 12y = 42
So, we have
18x - 2x + 12y - 12y = 42 + 17
Evaluate the like terms
So, we have
16x = 59
Divide both sides by 16
So, we have
x = 59/16
Substitute x = 59/16 in 3x + 2y = 7
3 x 59/16 + 2y = 7
This gives
177/16 + 2y = 7
So, we have
2y = 7 - 177/16
Evaluate the difference
2y = -65/16
Divide by 2
y = -65/32
Hence, the solution to the system where the system contains linear equations is (59/16, -65/32)

Un coche tarda 9hrs en recorrer un trayecto siendo su velocidad de 85km/h, ¿Cuánto tardará en recorrer el mismo trayecto a 70km/h?
Answers
The time taken to travel the distance 70 Km/h is 11 hours.
What is speed distance formula?Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took.
The formula can be rearranged in three ways:
speed = distance ÷ timedistance = speed × timetime = distance ÷ speedGiven:
time = 9 hours
speed = 85 Km/h
Now, distance
=speed * time
=85 * 9
= 765 km
As, the speed is 70 km/h
time = distance/ speed
time = 765 / 70
time = 10.92
time= 11 hours
Hence, the time taken to travel the distance 70 Km/h is 11 hours.

The function f₁(x) can be either vertical stretch or vertical compress: TRUE
What do we mean by Logarithmic Function?The following is the formula for basic logarithmic functions: Where b > 0, f(x) = logbx(r), y = logbx.It is the reciprocal of the exponential function x=b∧y.Log functions are denoted by natural logarithm (ln) and common logarithm (log).Here are a few examples of logarithmic functions:
f(x) = ln (x - 2)g(x) = log2(x + 5)-2h(x) = 2 log x, etc.So,
Given function:
f(x) = bˣg(x) = logbxThen,
f₁(x)=b^(x-h)f₁(x)=b^x/b^hNow, Put bˣ=f(x):
f₁(x)=f(x)/b^hf₁(x)=b^(-h)f(x)f₁(x)=c f(x)We discovered that:
c=b^(-h)So, depending on the values of b and h, c can be greater than or less than one.

If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.
What is the missing length of the triangle?
We are given a triangle with the condition that BA ≅ CA. This means that side BA has a length equal to that of side CA.
Now, an Isosceles triangle is defined as a triangle that has at least two sides of equal length. This means that the given triangle ABC is an Isosceles triangle.
Now, since Triangle ABC is an Isosceles triangle, it means that when we draw a perpendicular line through the point joining the two equal sides, it bisects the third side of the triangle.
Thus, it means that BD is congruent to CD.
If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.

Answers
An equivalent form of 5 / ( 2 + 2 i ) is ( 5 -5 i ) / 4 [ option I ]
Given,
5 / ( 2 + 2 i )
To find its equivalent form we need to simplify the term by using the concept of conjugates.
Conjugate of a term results in opposite power of the imaginary part.
The conjugate of 2 + 2 i = 2 - 2 i
Multiply and divide the term with the conjugate
=> 5 * ( 2 - 2 i ) / ( 2 + 2 i ) * ( 2 - 2 i )
=> 10 - 10 i / 2 ² - ( 2 i ) ² [ ( a + b ) ( a - b ) = a ² - b ² ]
=> 10 - 10 i / 4 - (-4) [ i ² = - 1 ]
=> 10 - 10 i / 8
=> 5 - 5 i / 4
This matches with option I

After playing 100 times the player will loose $-16.67.
Given the outcomes and the probability is:
Outcome Probability
-$10 1 (cost to play)
$14 draw red 5/12
$12 draw yellow 4/12
therefore, expected probability = ∑x.p(x)
x is no of trials and
p(x) is probability of the results.
E(x) = (14)5/12 + (12)4/12 + (0)3/12 - 10
E(x) = -2/12
E(x) = -10.1667
For 100 games the expected value E(100x) =

I am a 4-digit number larger than 2,500. No two of my digits are the same. The product of the thousands digit and the hundreds digit is equal to the ones digit. The sum of my digit is 16.
Read the clues. Find the number
Answers
Step-by-step explanation:
4-digit number abcd
a >= 2
a×b = d
so, 2 <= b <= 4 to allow a single digit result of a×b, and if b would be 1 or 0, the result would be either a copy of a or of b violating the rule that no 2 digits are the same.
that means a >= 3, because with a = 2 and b <= 4 the number can't be larger than 2500.
and that again means 2 <= b <= 3 and 3 <= a <= 4 to allow a single digit result of a×b.
the sum of "my digit" ? I guess you mean the sum of all digits is 16.
a + b + c + d = 16
so, my first guess :
a = 3
b = 2
therefore
d = 3×2 = 6
that means we have already 11 as sum of the digits, that leaves 5 for c.
so, the number would be
3256
the only alternative would start with a = 4 and then b = 2.
but that would make d = a×b = 8. abd 8 + 4 + 2 = 14, and that leaves for c only 2 to sum up to 16, and that would duplicate b.
so, 3256 is the only solution.

What is a rational number?
Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.
Calculation of the product of two rational numbers
Given two rational numbers,
8y - 4 / 10y - 5 and 5y -15 / 3y - 9
We need to multiply both the numbers i.e.
= (8y - 4 / 10y - 5) × (5y -15 / 3y - 9)
= (8y -4) × (5y - 15) / (10y - 5) × (3y - 9)
= (40y² - 140y + 20) / (30y² - 105y + 45)
= (8y² - 28y + 4) / (6y² - 21y + 9)
= (8y² - 28y + 4) / (6y² - 21y + 9)
The restriction is that the denominator, 6y² - 21y + 9 should not be 0.
Hence, the required product of two rational numbers is 8y2 - 28y + 4) / (6y2 - 21y + 9).
