HELP PLZ 5x + -9 + 3x - 20 =

1 answer:

6 0

Add like terms. "Like terms" are those with the same constellation of variables.
.. terms with variable x: 5x +3x = (5 +3)x = 8x
.. terms with no variable: -9 -20 = -29

The simplified form is 8x -29.

If A is a 5 by 7 matrix, what is the maximum rank that A can have?

amm1812

Answer:

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix $5\times 7$ the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.

An unfair coin is twice as likely to land "Heads" as "Tails". If the coin is tossed twice, what is the probability that it will

Ierofanga [76]

The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25. A visual representation of the toss of two coins. The Product Rule is evident from the visual representation of all possible outcomes of tossing two coins shown above.

Explain why f(x) = x2+4/x2-x-2 is not continuous at x = 2.

xxTIMURxx [149]

Answer: Option a.

Step-by-step explanation:

Make the denominator equal to zero and solve for x:

Factor the quadratic equation. Find two number whose sum is -1 and whose product is -2. Then:

$x^{2}-x-2=0\\(x-2)(x+1)=0\\x=2\\x=-1$

Then, as you can see the value x=2 makes the denominator equal to zero and the division by zero does not exist. Therefore you can conclude that the function shown in the problem is not defined at x=2

The answer is the option a.

Which expressions go in which box?

almond37 [142]

To qualify as a polynomial, the expression in question:
* Consists of one or more terms
* Variables are only with positive whole exponents
* No variables in the denominator of any term (the coefficients however, can be fractions.)

In that case the answer is most likely:
