Answer:
y=7/5x+26/5 and y=-5/7x+66/7
Step-by-step explanation:
if it's parallel, it needs to have the same slope, so the equation is y=7/5x+26/5. the perpendicular line is y=-5/7x+66/7.
-v/9-5/9 I really don't know if it's fully correct, but I hope it is!
The odd numbers between 1 and 7 are: 3 and 5. If we add all those numbers including 1 and 7, we have: 1 + 3 + 5 + 7 = 16.
Answer:
To solve, use a simple one-step equation
Known: Number of coins; Number of Nickles.
Unknown: Number of Dimes.
a) To find the number of Dimes
b) Use x (or virtually any letter) to represent the unknown number of dimes
c) 9+x=13
d) Subtract 9 from both sides to cancel out the 9 and isolate the variable on one side. x=4
e) 9+4=13, so yes, the answer is correct
