This is saying that ABC is conguent with LMN meaning all the sides are the same, making it safe to assume that AB is equal to LM. This also means that the equations for both are equal to each other
-3y + 10 = 2y + 15
-5y = 5
y = -1
Then to find AB you plug the -1 in for the y value
-3(-1) + 10 = 13
Knowing these 2 parts, the answer is A
Answer:
x > 5
Step-by-step explanation:
3+x>8
Subtract 3 from each side
3-3+x>8-3
x > 5
Addition, subtraction, multiplication.
Addition: The addition of two integers produces another integer.
Subtraction: The subtraction of two integers produces another integer.
Multiplication: The product of two integers is an integer.
Division between two integers can produce a rational number that is not in the set of integers e.g. 1/3
This only includes the four basic arithmetic operations, you can include exponentiation and the modulo operation if you want to for the same reasons as above.
Because all the coordinates of a line has the same slope. So, we can use any two of them to find the slope.
