Answer:
A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.
Answer:
First, you change each number to an improper fraction, simplify if possible. Then Multiply the numerators and then denominators, put your answer at lowest terms.
I really hope this helped.!
Percentage = (1352/40929) x 100%
percentage = 0.03303281292 x 100%
percentage = 3.30%
Answer:
The roots of the equation is real and repeated
Step-by-step explanation:
Here, we want to describe the nature of the roots of the given quadratic equation
To get the nature of the roots, we find the discriminant of the equation
The discriminant is;
b^2 - 4ac
In this case, b = -28 , a = 49 and c = 4
The discriminant is thus;
-28^2 - 4(49)(4)
= 784 - 784 = 0
Since the discriminant is zero, this means that the quadratic equation has real roots which are the same
The answers D, the explanation is that it’s basically common sense just look for the same numbers and make it make sense :)
