1 answer:
Naya [18.7K]3 years ago
3 0

Answer:

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of<em> 2 ounces lost per second.</em> Now that we know the slope, we can answer the questions

A.  We can get the equation by finding the y int. (below) and writing it as y=-2x+68

B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= <u><em>68 ounces at the beginning. </em></u>

C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: <em>After 34 seconds.</em>

Step-by-step explanation:

:D hope this helps

Which letters from the table represent like terms? A and B B and C A and D B and D.
xenn [34]

The letters can be added together if they have similar variables.

B and C are like terms. Option B shows the like terms of letters.

<h3>What is a binomial?</h3><h3></h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign is called the binomial expression.

The attachment shows the table of letters and variables.

To multiply binomials, a form of the distributive property is used.

The table has been complete with the final values of letters which are given below.

A= (-2x) \times 4x

A = -8x^2

B = 3 \times 4x

B = 12 x

C = (-2x)\times 1

C = -2x

D = 3\times 1

D = 3

From the final values of letters, B and C are the only like terms, they can be added together since they have similar variables.

Hence we can conclude that B and C are like terms. Option B shows the like terms of letters.

To know more about the binomials, follow the link given below.
