Answer:
Step-by-step explanation:
1). (B). Replace one equation with the sum/difference of both equation.
System B is
- 4x - 6y = 9 ........ <em>(1B)</em>
-4x + 3x = - x
- 6y + y = - 5y
9 - 4 = 5
- x - 5y = 5 ........ <em>(2B)</em>
2). Yes, both system are equivalent.
Answer:
correct answer: A)8
Step-by-step explanation:
Answer:
The coefficient is 7
Step-by-step explanation:
The coefficient of an algebraic expression is the number that is being multiplied by a variable or multiple variables. In this case, 7 is being multiplied by x and y, so 7 is the coefficient.
Answer:
1. C -> Marty's with a slope of 1/3
2.C -> 2x + 5y = -15
3. C -> y = 1/4x + 2
4. A -> x - 4y = 8
5. D -> 5
