Which expressions are equivalent when y = 2 and y = 5? 2 y minus 1 and 3 y minus 5 + y 5 y + 4 and 7 y + 4 minus 2 y y + 7 and y

noname [10]

Answer:

Option b

Explanation:

The question is shown in the attached image

To answer this question, we will simply substitute in the given expressions with the values y=2 and y=5

The correct option will be the one having equal vales in both cases

1. Option a:

At y = 2:

2y - 1 = 2(2) - 1 = 3

3y - 5 + y = 3(2) - 5 + 2 = 3

At y = 5:

2y - 1 = 2(5) - 1 = 10

3y - 5 + y = 3(5) - 5 + 5 = 15

This option is incorrect, since both expressions are not equal at y = 5

2. Option b:

At y = 2:

5y + 4 = 5(2) + 4 = 14

7y + 4 - 2y = 7(2) + 4 - 2(2) = 14

At y = 5:

5y + 4 = 5(5) + 4 = 29

7y + 4 - 2y = 7(5) + 4 - 2(5) = 29

This option is correct, since both expressions are equal at the two vales of y

3. Option c:

At y = 2:

y + 7 = 2 + 7 = 9

y + 2 + y = 2 + 2 + 2 = 6

At y = 5:

y + 7 = 5 + 7 = 12

y + 2 + y = 5 + 2 + 2 = 12

This option is incorrect, since both expressions are not equal at y = 2

4. Option d:

At y = 2:

3y - 4 = 3(2) - 4 = 2

3y - 2 + y = 3(2) - 2 + 2 = 6

At y = 5:

3y - 4 = 3(5) - 4 = 11

3y - 2 + y = 3(5) - 2 + 5 = 18

This option is incorrect, since both expressions are neither equal at y = 2 or y = 5

Hope this helps :)

what we know: complete 6.8 square feet every hour

what we want to know: how much square feet will be compeletein 12 1/2 hours?

12 1/2 is 12.5

6.8 square feet time 12.5 hours gives you 85 square feet :)

Enrique says is a rational number. Which of the following best describes if Enrique is correct?

olasank [31]

If a number is rational it means, it can be written in the form of $\frac{p}{q}$ , where q≠0 and p and q can be any integers.

There are following properties possessed by Rational numbers

1. Decimal representation of Rational numbers are either terminating or non terminating repeating i.e if the denominator is of the form $2^m or 5^n or (2^m \times 5^n)$ where m and n are any natural number.

2. Addition ,Subtraction ,Multiplication and Division of two rationals is always Rational.

3. The sum or difference of rational and irrational is always irrational.
