The system of equations will have no solutions if the two lines are parallel, then one example can be:
5x - 2y = 1
15x - 6y = 0
For which values of a and b the system has no solutions?Here we have the following system of equations:
5x - 2y = 1
a*x - 6y = b
The system will have no solutions only if the two equations are parallel. You can see that the coefficient of y on the second equation is 3 times the coefficient on the first equation.
Then a should also be 3 times the coefficient of x on the first equation:
a = 3*5
a = 15
And b should be any number but 3 times the constant on the other equation:
b ≠ 3*1
So we can take b = 0, for example.
So the system with no solutions will be:
5x - 2y = 1
15x - 6y = 0

The answer to the stated domain range puzzle is 0.
What exactly are a domain and range?both domain and range. The range of values that can be plugged into a function is known as its domain. In a function like f, this set represents the x values (x). The values that the function outputs when we enter an x value are in this set.
What do a function's domain and range consist of?The collection of all possible inputs and outputs constitutes a function's domain and range, respectively. Important features of a function are the domain and range.
According to the given information:(f(g)(x) = (√x)² - 1
(f(g)(x) = x - 1
(f(g)(x)(1) = 1 - 1 = 0

What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
We graph both equations in the same coordinate system in order to visually solve a system of linear equations. The intersection of the two lines is where the system's answer will be found. The point where the two lines join is (-3, -4), which is where this equation system's solution lies.

Cardi B uses 1/2 cup of sugar to make 4 1/3 batches of brownies. How much sugar is required to make each batch of brownies?
The sugar required to make each batch of brownies is 3/26 cups
How to determine how much sugar is required to make each batch of brownies?From the question, we have the following parameters that can be used in our computation:
Brownies = 4 1/3 batches
Sugar = 1/2 cups
The amount of sugar required to make each batch of brownies is then calculated as
Sugar needed = Sugar/Brownies
Substitute the known values in the above equation, so, we have the following representation
Sugar needed = (1/2)/(4 1/3)
Evaluate
Sugar needed = 3/26
Hence, the amount is 3/26 cups
