In quadratic equations,
a + b = -B
ab = C
where a and b are the roots, B is the second term, and C is the constant.
Substituting,
a + b = -12
ab = 35
The values of a and b from the equation is -7 and -5. Thus, the lesser root is -7.
Answer:
1. the y-intercept is 9.5 and it means the starting length of the candle
2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour
3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
Now:
kimberly = k
jordan = k - 102
2 years ago
kimberly = k - 2
jordan = k - 104
k - 2 = 4(k - 104)
k - 2 = 4k - 416
-3k = -414
k = 138
kimberly is 138
jordan is 138 - 102 = 36
k - 102 = 36
2*(X-2+3x+5)=94 cm
4x+3 = 47
4x=44
x=11 cm
Answer:
3.5 hours*3.25 mph=11.375 miles
11.375 miles/3.45 mi/hr=3.297 hours or 3.30 hours, about 12 minutes faster.
