Sry I don’t know try Socratic
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
X^2+4x-12
x^2+6x-2x-12
x(x+6)-2(x+6)
(x-2)(x+6)
So, B is the answer
Answer:
A function is a relation in which no two ordered pairs have the same first element. A function associates each element in its domain with one and only one element in its range. Solution: a) A = {(1, 2), (2, 3), (3, 4), (4, 5)} is a function because all the first elements are different.
Step-by-step explanation:
Unit of measurement in a formula suggests a definite magnitude of a certain quantity. For instance, there are basic unit of measurement for the 7 basic quantities: These are
1. seconds (s) for time
2. meter (m) for length
3. candela (cd) for luminous intensity
4. Ampere (A) for electric current
5. Kelvin (K) for Temperature
6. Kilogram (kg) for mass
7. mole (mol) for amount of substance
These units of measure should be homogenous in a formula for easy interpretation. Other derived quantities (e.g volume) also have their corresponding units as well as those quantities which are not based on the metric systems (e.g Celsius, pounds, etc)
