The answers are x=2 and y=5. 2(2)=4. 4+5=8. y=x-7 then is converted into 5=2-7.
Answer:
Step-by-step explanation:
Distance Formula: 
Simply plug in your 2 coordinates into the formula to find distance <em>d</em>:
Step-by-step explanation:
According to Boyle's Law :
100 cm is equal to 1000m, so yes it is equal
X + 5y = 14
5y = -x + 14
y = -1/5x + 14/5.....the slope here is -1/5. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular slope will be 5. See how I flipped -1/5 making it -5/1...and then changed the sign, making it 5.
y = mx + b
slope(m) = 5
(-5,-2)....x = -5 and y = -2
now we sub and find b, the y int
-2 = 5(-5) + b
-2 = -25 + b
-2 + 25 = b
23 = b
so ur perpendicular equation is : y = 5x + 23 <==
