Answer:
Step-by-step explanation:
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.Understand what multi-variable equations are. Two or more linear equations that are grouped together are called a system. That means that a system of linear equations is when two or more linear equations are being solved at the same time.[1] For example:
8x - 3y = -3
5x - 2y = -1
These are two linear equations that you must solve at the same time, meaning you must use both equations to solve both equations.
So the angles inside the triangle add up to 180
95+25+x=180
120+x=180
subtract 120 from both sides
x=60
answer is 60 degrees
It either B or D. zoz dnd keep
Answer: (3, 7)
Step-by-step explanation: The pattern seems to be dividing each axis by 2, so 6/2 = 3 and 14/2 = 7, making (3, 7)
Have a nice day! :)
Answer:
C: .94
Step-by-step explanation:
7e^x=18
x=ln(18/7)
x=ln(2.5714)
x=.94
