Answer:
It means direct sum.
Step-by-step explanation:
Answer:
m=-1/3
Step-by-step explanation:
To find the slope you have to use the equation:y₂-y₁ divided by x₂-x₁
So you would have 3-4 divided by 0-(-3)
And then you would get -1/3
Answer:
y variable will be elimited when adding the system of equations
x = 2 or y = 3
Step-by-step explanation:
- x + 6y = 16
8x - 6y = -2
Add both equations
(-x + 8x) + {6y + (-6y)} = 16 + (-2)
7x + 6y - 6y = 16 - 2
7x + 0 = 14
7x = 14
x = 14/7
x = 2
- x + 6y = 16
- 2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
the x variable will be eliminating when adding the system of equations and the
y variable will be elimited when adding the system of equations
or the sum of the system equations is negative 8X = 14 or
x = 2 or y = 3
or there's only one solution to the system equations

The factored form of the expression 10x² -x - 2 is (5x+2)(2x-1)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 10x² -x - 2
Factorize the given expression
10x² -x - 2
Separate the middle term into -5x and 4x to have;
10x² - 5x + 4x - 2
Factor out the GCF
5x(2x-1)+2(2x-1)
Hence the factored form will be;
(5x+2)(2x-1)
The factored form of the expression 10x² -x - 2 is (5x+2)(2x-1)
