Answer:
Blue (p): x = -4
Red (l) : y = 4
Black (m): y = -2x + 4
Green (n): y = x - 1
Step-by-step explanation:
For the first two, red and blue, you just simply look at what axis they lie on, and what point! Since blue is on the x, its x = -4.
The remaining two lines, I always look for the y-intercept first! You should write that down, then use RISE/RUN to figure out the slope!
I hope this helps, and I'll be here if you need me!! Have a nice day :D
Answer:
3/2 or 1.5 or 1 1/2

To divide, you must switch the -1/4 to its reciprocal which is -4/1 and then multiply the fractions (-3/8 * -4/1) and since negative - negative = positive. It's a positive.
Answer:
20% decrease in value.
Step-by-step explanation:
Do 650,000 divided by 100 to find what 1% of the original price is:
650,000 divided by 100 = 6,500
To find what percentage of the original price 520,000 is, we divide it by 1% of the original cost (6,500):
520,000 divided by 6,500 = 80 (percent)
So if 520,000 is 80% of 650,000 the car has decreased in value by 20%.
