Answer:
(5, - 2 )
Step-by-step explanation:
Given the 2 equations
9x + 5y = 35 → (1)
- 2x - 5y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations for value of y
Substituting in (1) gives
9(5) + 5y = 35
45 + 5y = 35 ( subtract 45 from both sides )
5y = - 10 ( divide both sides by 5 )
y = - 2
Solution is (5, - 2 )

Answer:
D
Step-by-step explanation:
definitely
Answer: A
Step-by-step explanation:
An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.
y = -5x - 4
Test:
-52 = -5(10) - 4
-52 = -54 FALSE
Answer:
3(z-6)
Step-by-step explanation:
First Subtract 6 from z,
=> z - 6
then multiply by 3,
=>3(z-6)
