Answer:
13 - 17
Step-by-step explanation:
Using the rule
× = a
Each term in the second factor is multiplied by each term in the first factor, that is
2 ( - 9 ) + 1 ( - 9 )
Distribute both parenthesis
= (2 × 11) - 18 + - 9
= 22 - 17 - 9
= 13 - 17
Answer:6x - 2y = 22
Step-by-step explanation:
Just multiplying equation by 2
Can do it with any number
A parallel line to y = -3x+7 with a y intercept of 0 is
y = -3x + 0, or you could simply write it as y = -3x
Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ( this symbol). When you do that, you should get what x is! Let me know if you still need help!
Answer: Infinite Solutions
Step-by-step explanation:
Since 12=12 is a true statement, any value of x will work for that system of equations.
Hope this helps!
