System Linear equation has no solution , because it is paralell lines but no intersection.
What is system linear equation?
An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.
Here the given system linear equations,
[tex]3y=\frac{3}{2}x+6[/tex] -------> 1 and [tex]\frac{1}{2}y-\frac{1}{4}x=3[/tex] --------> 2
Divide by 3 of equation 1 on both sides then,
[tex]y=\frac{1}{2}x+2[/tex] -----------> 3
Now put 3 into 2 then,
=> [tex]\frac{1}{4}x+1-\frac{1}{4}x=3[/tex]
=> 1=3
Hence the given system equation has no solution , because it is paralell lines but no intersection.

D. x < 5.2
E. 0
F. x< -5.2 or x> 5.2
The solution set x<-5.2 or x>5.2 is true for the inequality |x|>5.2.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides.
The given inequality is |x|>5.2.
So, the value of x should be greater than 5.2.
For example take x=6, then the given inequality will be -
|6|>5.2 = 6>5.2, so this is true.
Now take x=-6, then the given inequality will be -
|-6|>5.2 = 6>5.2, so this is also true.
Similarly, among the different choices x<-5.2 or x>5.2
The condition x>5.2 is already true.
Also, the condition x<-5.2 is also true for x if the value is lower than -5.2.
Therefore, the inequality x<-5.2 or x>5.2 is true.

The measure of an angle is 89
Find the measure of its supplement.
We can conclude that the supplement angle of 89° will be 91°.
What do we mean by supplement angles?Angles that add up to 180 degrees are referred to as supplementary angles.
For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
The sum of complementary angles is 90 degrees.
Two angles are complementary if their sum equals 90 degrees, and supplementary if their sum equals 180 degrees.
So, we have an angle of 89°.
We know that the supplement angle is an angle of measure 180°.
Now, the supplement angle of 89° will be as follows:
180 - 89
91°
Therefore, we can conclude that the supplement angle of 89° will be 91°.

To simplify fractions, we should follow these steps:
Step 1: Write the factors of the numbers in the numerator and denominator in step one.Step 2: Determine the shared factors that both the numerator and the denominator share.Step 3: At this point, we must divide the numerator and denominator by each other until there is only one other common component left.
Here, the given fraction is 4/28.
At first, we need to write the factors of the numerator and the denominator
Factors of the numerator, 4 = 1, 2, 4.
Factors of the denominator, 28 = 1, 2, 4, 7, 14, 28.
So, the common factors are 1, 2 and 4.
Dividing the numerator and denominator by the common factor, 2;
(4/2) / (28/2) or,

How to find the change in temperature?We are told that;
The freezer should be working at -18°C.
The temperature on the freezer marks -10°C.
Now, what we see here is basic arithmetic because we simply want to find the additional temperature that will make the current reading to be equal to the ideal temperature required for it to wor. Thus, what we will do is to simply subtract the current temperature from the ideal one to find out the temperature required to make it work well.
Thus;
Temperature change = -18 - (-10)
Temperature change = -18 + 10
Temperature change = -8°C.

What is integration ?
Integration is a process of finding an antiderivative of a function, it is the reverse process of differentiation. It can be thought of as the area under the curve of the function or the accumulation of the function over a certain interval.
Integration by parts is a technique that can be used to integrate a wide variety of functions, not only functions that include polynomials or exponential functions. In fact, integration by parts can be used to integrate any function that can be expressed as the product of two functions, where one of the functions is the derivative of the other function. In other words, integration by parts allows us to evaluate an integral of the form ∫u(x)dv(x)dx by expressing it in terms of an integral of the form ∫v(x)du(x)dx.
