Answer:
2x (2 or 2/1)
Step-by-step explanation:
The slope is 2/1, or 2x because the height between any two given intercepting points is two times higher than it is far.
Take for example the intercepting points at (6, 1) and (7, 3). Since slope is rise/run, the slope has risen 2 and 'run' 1. This makes the slope 2/1.
Answer:
The iPhone is cheapest in Paris, where it costs £701.75.
Step-by-step explanation:
Divide each price by the conversion factor.
Answer:
x=1 y=19
Step-by-step explanation:
Let's solve your system by elimination.
−9x+y=10; 10x−y=−9
−9x+y=10
10x−y=−9
Add these equations to eliminate y:
x=1
Then solve x=1 for x:
x=1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
−9x+y=10
Substitute1forxin−9x+y=10:
(−9)(1)+y=10
y−9=10(Simplify both sides of the equation)
y−9+9=10+9(Add 9 to both sides)
y=19
Hope this helps, I don't really get the answer choices though....
