Which ordered pair is a solution of the equation y = 3x+5
Daniel [21]

Answer:

All you have to do is insert the first value where the x is, and the second value where the y is.

y = 3x + 5

11 = 3(2) + 5

11 = 6 + 5

11 = 11

So, this is right.

Now, let's check (3,13)

y = 3x + 5

13 = 3(3) + 5

13 = 9 + 5

13 = 14

This is NOT true. So, your answer is: Only (2,11)

Hope this helps!

seraphim [82]

Answer:

The shopper should but the 6 pcs pack because its cheaper.

Step-by-step explanation:

6-pcs pack = $2.10

hot dogs needed = 48

number of 6 pcs = 48 divided 6 = 8

total cost = $2.10 x 6 = $16.80

8 pcs pack = $3.12

hot dogs needed = 48

number of 8 pcs packs = 48 divided 8= 6

total cost = $3.12 x 6 =$18.72

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What
Oksana_A [137]

Using the domain concept, the restrictions on the domain of (u.v)(x) are given by:

A. u(x) ≠ 0 and v(x) ≠ 2.

<h3>What is the domain of a data-set?</h3>

The domain of a data-set is the set that contains all possible input values for the data-set.

To calculate u(x) x v(x) = (u.v)(x), we calculate the values of u and v and then multiply them, hence the restrictions for each have to be considered, which means that statement A is correct.

Summarizing, u cannot be calculated at x = 0, v cannot be calculated at x = 2, hence uv cannot be calculated for either x = 0 and x = 2.
