Answer:

5abc^2/35a^3c^3

Step-by-step explanation:

To bring the fraction: b/7a^2c to a denominator of 35a^3c^3, find the dividend when the 35a^3c^3 is divided by 7a^2c

=35a^3c^3/ 7a^2c

Recall that

a^x/a^y = a^x-y

Hence

35a^3c^3/ 7a^2c = 5a^3-2c^3-1

= 5ac^2

Now multiply the numerator and denominator by the result

b/7a^2c = (b * 5ac^2)/(7a^2c * 5ac^2)

Recall that

a^x * a^y = a^x+y

Hence

b/7a^2c = (b * 5ac^2)/(7a^2c * 5ac^2) = 5abc^2/35a^3c^3

If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Mama L [17]

Answer:

x can be any value, x will be the input, y will be the output.

Step-by-step explanation:

If x = 3, If x = 6, If x = 9,

y = 5x - 4

y = 5 (3, 6, or 9) - 4

y = 11, y = 26, y = 41.

These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.

X (Input) I Y (Output)

3 I 11

6 I 26

9 I 41

See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.

What is the relationship between the 6s in the number 660,472

scoundrel [369]

Answer:
The first 6 is 10 times greater than the second one

Explanation:
The given number is 660,472
This number can be rewritten as:
660,472 = 600,000 + 60,000 + 400 + 70 + 2

Now, comparing this to the place-value chart shown in the attached image, we would find that:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
The 0 represents the thousands of the number
The 4 represents the hundreds of the number
The 7 represents the tens of the number
The 2 represents the ones of the number

Now, we are comparing the values of the 6s:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
This means that:
The first 6 is 10 times greater than the second one

Hope this helps :)
