Find the solution set (x+1)(x+1)=0

Answers

Answer 1

Answer: x= -1 beacuse negative one plus one is 0 and that will equal zero for both sides

Answer 2

Answer: (x+1)(x+1)
x²+2x+1=0
x²+1x+1x+1=0
x(x+1)+1(x+1)
(x+1)(x+1)
x=-1

reduce the fraction so that it's 4/21
The ratio would be 4:21

Whats the mean, media, maximum,minimum,mode and range of 1,2,1,3,4

Answers

First put the numbers in order least to greatest.
(1,1,2,3,4)
The mean is the average of the group of numbers.
Too find it you add all the numbers up and divide it by how many numbers there are.
In this case it would be 11 divided by 5 so the mean would be $2 (1)/(5)$

Median is just another word for middle. After putting the numbers in order, the number in the center of the group is the median, in this case it would be 2.

The maximum would just be the largest number which is self explantory (4)

The minimum would be the lowest number (1)

I was taught to see mode as the word "most". All you do is see which number occurs the most. If all the numbers only occur once, your answer would be "No mode"

It is that simple! The Range is the difference between the lowest and highest number. So all you have to do is subtract the maximum by the minimum. In this case it would be 4-1 = 3

What is the value of the system determinant for the following system of equations? 6x + y = 4 5x + y - 7 = 0

Answers

Answer: The value of the determinant is 1.

Step-by-step explanation: The given system of linear equation is as follows:

$6x+y=4~~~~~~~~~~~~~~~~(i)\n\n5x-y-7=0\n\n\Rightarrow 5x-y=7~~~~~~~~~~~(ii)$

The first column of the determinant gives the coefficients of 'x' and the second column gives the coefficients of y in the two equations.

Therefore, the determinant for the given system is

$D=\begin{vmatrix} 6& 1\n 5& 1\end{vmatrix}=6* 1-5* 1=6-5=1.$

Thus, the required value of the determinant is 1.

Can you please answer this question

-12+(-66)+48 and how

Thanks in advance

Answers

Answer:

-30

Step-by-step explanation:

so we will write the -12 as it is then multiply the positive sign by the negative sign of the num 66 (bc there are paranthesis around the number) it will be - sign (example 2+(-6) is equal to -4 and because the negative sign over powers the positive sign) then we will write the +48 as it is so it will be -12-66+48 = -30 (answer is negative bc its the sign of the biggest number)

really hope this helped and good luck!
