Y= 5x - 9; domain = { 1,3,7 }<br> what is the range values?

Maslowich

Answer:

Step-by-step explanation:

range = [-4,6,26]

Step-by-step explanation:

y = 5x - 9.....domain = [1,3,7]....the domain is ur x values, and I am assuming ur looking for the y values that go with the x ones

y = 5x - 9.....when ur domain (ur x) = 1

y = 5(1) - 9

y = 5 - 9

y = -4

y = 5x - 9...when ur domain (x) = 3

y = 5(3) - 9

y = 15 - 9

y = 6

y = 5x - 9...when ur domain(x) is 7

y = 5(7) - 9

y = 35 - 9

y = 26

so ur range (ur y valus) = [-4,6,26]

Which set of ordered pairs could be generated by an exponential function?

Tems11 [23]

Answer:

The correct option is C) $(1, \frac{1}{2}), (2, \frac{1}{4} ), (3,\frac{1}{8} ), (4,\frac{1}{16})$

Step-by-step explanation:

Consider the provided ordered pairs.

The function will be exponential function if the ratio of y value remains the same.

Consider the option

Option A: $(1, 1), (2, \frac{1}{4} ), (3,\frac{1}{3} ), (4,\frac{1}{4} )$

The ratio of 1/4 and 1 is 1/4 but the ratio of 1/3 and 1/4 is not 1/4.

Therefore, option A is incorrect.

Option B: $(1, 1), (2, \frac{1}{4} ), (3,\frac{1}{9} ), (4,\frac{1}{16})$

The ratio of 1/4 and 1 is 1/4 but the ratio of 1/9 and 1/4 is not 1/4.

Therefore, option B is incorrect.

Option C: $(1, \frac{1}{2}), (2, \frac{1}{4} ), (3,\frac{1}{8} ), (4,\frac{1}{16})$

The ratio of 1/4 and 1/2 is 1/2, the ratio of 1/8 and 1/4 is 1/2

Similarly the ratio of 1/16 and 1/8 is 1/2,

Therefore, option C is correct.

Option D: $(1, \frac{1}{2}), (2, \frac{1}{4} ), (3,\frac{1}{6} ), (4,\frac{1}{8})$

The ratio of 1/4 and 1/2 is 1/4 but the ratio of 1/6 and 1/4 is not 1/4.

Therefore, option D is incorrect.

A farmer has 220 bushels of apples to sell at roadside stand. She sells an average of 14 3/5 each day. Represent the total chang

Lyrx [107]

Answer:

Step-by-step explanation:

He has sold (16+1/4) bushels/day x 5 days = (16 x 5) + (1/4 x 5) = 80 + 5/4 = 81 + 1/4 = 81.25

The change in the number of bushels is 140 - 81.25 = 58.75 or 58 and 3/4 bushels

In other words, he has 58.75 (or 18 and 3/4) bushels remaining and has sold 81.25 (or 81 and 1/4) bushels
