PLEASE HELP ASAP

Mathematics
1 answer:
il63 [147K]3 years ago
8 0

Step-by-step explanation:

The problem asks to find the values "b" and "c" in a way that

the solutions of the equation |x - b| = c are x= 1/2 and x= -1/3.

It means that "b" is the center of the segment [-\frac{1}{3} ,\frac{1}{2}].

This segment has the length \frac{1}{2} - ( - \frac{1}{3} = \frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}  Hence, the half of this length is \frac{5}{12}.

Therefore, the center of the segment is \frac{1}{2} - \frac{5}{12} = \frac{6}{12} - \frac{5}{12}  = \frac{1}{12}

Thus the value of "b" is found: it is b = \frac{1}{12}.

Then the value of "c" is  c =\frac{1}{2} - \frac{1}{12} = \frac{5}{12}.

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amo
sveticcg [70]

The options aren't given, however, the range of amount spent could be calculated

Answer:

Kindly check explanation

Step-by-step explanation:

Paula purchase 3 dvd and 7 cds and spent between 90 and 100. Each dvd costs the same amount the price of cd is 10 select all amounts that could be the price of the dvd

Given that :

DVD costs the same amount

Number of DVD's = 3

Cost of cds = 10

Number of cds = 7

Total cost of cd's = 10 * 7 = 70

Let the price of DVD = x

Total amount spent = 90 - 100

Lowest price of DVD :

(amount spent - price of cd) / number of dvd

(90 - 70) / 3 = 20 /3 = 6.667

Highest price :

(100 - 70) / 3 = 30 / 3 = 10

Hence the pice of each DVD will range between /

6.6666 and 10.

Hence, prices listed within the range above are possible.

The height of a ball dropped from the top of a 450-foot tall building can be described by the expression
BaLLatris [955]

Answer:

The answer is 386 feet.

Step-by-step explanation:

This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.

Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.
