Answer:
she will spend 10 hours in class 40 hours studying and 20 hours working
Step-by-step explanation:
if u simply start at 1 hour of class u get to see the pattern example:
class. study. work
1 4. 2
she works twice as long as she is in class and studies 4 times longer than in class so for every hour she is in class do the math for this condition. for every class hour multiply by 4 to get her study time and then multiply her class hour by 2 to get her work hours. keep going until the total time of all activities adds to 70
Answer:
2x^{4}
Step-by-step explanation:
You would subtract 7 and 5 and you would leave the exponent so it would be 2x^{4}
FG : (3,7)(-4,-5)
slope = (-5 - 7) / (-4-3) = -12/-7 = 12/7
y = mx + b
slope(m) = 12/7
(3,7)...x = 3 and y = 7
now we sub, we r looking for b, the y int
7 = 12/7(3) + b
7 = 36/7 + b
7- 36/7 = b
49/7 - 36/7 = b
13/7 = b
so ur equation is : y = 12/7 + 13/7.....slope = 12/7, y int = 13/7
HI : (-1,0)(4,6)
slope = (6 - 0) / (4 - (-1) = 6/5
no need to go any farther.....these lines have different slopes...and their not negative reciprocals....so there will be one solution. Answer is : neither.
