What are odd and even numbers?A number that can be split into two equally sized groups is said to be even. A number that cannot be split into two equal groups is said to be odd.No matter how many digits they have, even numbers always end in 2, 4, 6, 8 or 0. Odd numbers end with 1, 3, 5, 7, and 9.Any number multiplied by an even number gives an even number.Let us consider an input = number (n) × even number.
So, the output is definitely an even number.
The output is always an even integer for every input. Odd numbers end in the digits 1, 3, 5, 7 while even numbers conclude in the numerals 0, 2, 4, 6, 8. In this instance, we can multiply any x number by any even integer to obtain an even number.

Solve each equation. 0.2(x+3)-4(2 x-3)=0.9
The solution of the given linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is at x = 1.5.
According to the given question.
We have a linear equation in one variable.
0.2(x+3)-4(2 x-3)=0.9
As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofore, the solution of the linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is given by
0.2(x+3)-4(2 x-3)=0.9
⇒ 0.2x + 0.6 -8x + 12 = 0.9
⇒ -7.8x + 12.6 = 0.9
⇒ -7.8x = 0.9 - 12.6
⇒ -7.8x = -11.7
⇒ x = -11.7/(-7.8)
⇒ x = 1.5
Hence, the solution of the given linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is at x = 1.5.

What to do if B is negative in a transformation? Does it become a positive fraction or stay a negative fraction when reflected over the y axis?
Step-by-step explanation:
what is B in your question ? you did not tell us.
since you mention "fraction", I assume B is the slope of a line ?
if that is the case, please remember, the slope is (y coordinate change / x coordinate change) when going from one point of the line to another.
the way you phrased it I assume the slope was originally negative.
that means either the y difference or the x difference was negative (but not both, otherwise it would have been a positive fraction again).
let's look at what happens, when things get reflected across the y axis :
things go from the left side (negative x values) to the right side (positive x values) of the y axis or vice versa.
and things stay on the same side of the x axis (either above the x-axis with positive y values, or below the x-axis with negative y values).
so, that reflection causes the x values to flip their sign, but the y values stay the same.
so, if y was originally negative, then x must have been positive. after the reflection x is now negative too, that makes the y/x fraction -/- = +/+ positive.
if y was originally positive, then x must have been negative. after the reflection x is now positive too, that makes the y/x fraction +/+ positive.
therefore, in every case, the reflected slope fraction must be positive.
Find a new function g(x) transformed from f(x)=-x-2 such that g(x) is perpendicular to f(x) .
The new function is g(x) =-1(1/-x) +2.
The transformation of function f(x) to function g(x) is given by g(x)=A f(Bx+ H)+K. where the constant A scales the function vertically. (A negative A reflects the function about the x-axis B scales the function horizontally. (A negative B reflects the function on the y-axis.) H shifts the function horizontally, and K shifts the function vertically.
Convert f(x) to g(x)
where the conversion is g(x)=f(x)+2.
A perpendicular line has negative reciprocal slopes, so for g(x) to be perpendicular to f(x), we need to get the negative reciprocal of -x, which is -1(1/-x)
So, f(x)=-x-2 ; m = -1
From the above information, we get g(x) as follows.
g(x) =-1(1/-x) +2

Your dog takes off from your house after seeing a cat run across the street. If your dog started from rest and achieved 5.5 m/s in 3 seconds, what is the acceleration of your dog?
The acceleration of the dog is approximately 1.83 meter per second² .
Acceleration is defined as the rate of change of velocity . The change in velocity per unit time is acceleration.
The formula to calculate acceleration is given by acceleration = velocity ÷ time.Negative acceleration is called deceleration.Acceleration can be uniform or non-uniform.In the given problem the dog started from rest and achieved the final velocity of 5.5 m/s.
Let us use Newton's laws to write the equation:
v = u + at , where v is the final velocity , u is the initial velocity , a is acceleration and t is time.
The dog starts from rest so the initial velocity is 0.
given v=5.5 /s and t = 3 seconds
putting the values we get:
v = u + a t
or , 5.5 = 0 + 3a
or, a = 5.5/3 meters per seconds²
or, a = 1.8333... m/s²
or, a ≈ 1.83 m/s²
The acceleration of the dog is 1.83 m/s²

Malika was given a gift card for a coffee shop. Each morning, Malika uses the card to buy one cup of coffee. Each cup of coffee costs $2.50 and the original amount of money on the gift card was $45. Make a table of values and then write an equation for A,A, in terms of x,x, representing the amount money remaining on the card after buying xx cups of coffee.
The expression representing the amount remaining will be 45 - 2.50x.
Table of values
At x = 1 Amount = 42.50
At x = 2 Amount = 40.
How to illustrate the information?From the information, Malika uses the card to buy one cup of coffee. Each cup of coffee costs $2.50 and the original amount of money on the gift card was $45.
Therefore, the expression representing the amount remaining will be:
A = 45 - (2.50 × x)
A = 45 - 2.50x
At x = 1 Amount remaining will be:
= 45 - 2.50
= 42.50
At x = 2
A = 45 - 2.50x
A = 45 - 2.50(2)

Total surface Area of cross or soiled cylinders
The cylinder's total surface area includes the area of the curving surface as well as the areas of the two circle-shaped bases of the cylinder.
The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:
Area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bottoms, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.
(r2 + r2 + 2rh) is the cylinder's total surface area.

Step-by-step explanation:
a. What is the solution of this system of equations? 3x + 7y = 15 , 5x +2y = -4.
The solution of the system of equations involving 3x + 7y = 15 and 5x + 2y = -4 is (-2 , 3).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
3x + 7y = 15 (equation 1)
5x + 2y = -4 (equation 2)
Using the first equation, find the value of one variable, lets say x, in terms of the other.
3x + 7y = 15 (equation 1)
3x = 15 - 7y
x = 5 - (7/3)y
Substitute the equation of x to the second equation.
5x + 2y = -4 (equation 2)
5[5 - (7/3)y] + 2y = -4
25 - (35/3)y + 2y = -4
Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
25 - (35/3)y + 2y = -4
- (35/3)y + 2y = -4 - 25
-(29/3)y = -29
y = 3
Substitute the value of y in the equation of x.
x = 5 - (7/3)(3)
x = 5 - 7
x = -2
Hence, the solution of the given system of equations is (-2 , 3).
