Answer:
The equation which can be used to find the value of numbers
(x) + (x + 1) + (x + 2) = - 21
Step-by-step explanation:
Let the first no. is = x
Second number = x + 1
Third number = x + 2
The sum of three consecutive numbers = x + x + 1 + x + 2
Given that Three consecutive integers have a sum of –21.
Therefore
(x) + (x + 1) + (x + 2) = - 21
This is the equation which can be used to find the value of numbers.
3 4/5 rounds to 4
5 1/6 rounds to 5
4 x 5 = 20
I hope this helped! :)
Quadratic functions are second-order equations of the form y=ax^2+bx+c. Their graphs form parabolas. The defining characteristic of a quadratic is that the acceleration of the outputs is a constant.
Answer
(a)
(b)
Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following
So, if you know the inverse of 
then
For this case
Now for this case the inverse of A would be
Then when you multiply with the vector solution
So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
