Distributive property of the product of 127 and 32

1 answer:

7 0

127(32) could be re-written as (130-3)(30+2). To evaluate this, we'd use the distributive property of multiplication: 130(30) + 130(2) - 3(30) -3(2).

That comes out to 3900 + 260 - 90 - 6. Combine the positive terms. Then combine the negative terms. Last, combine the single positive term with the single negative one: 4160 - 96 = ?

From the graph of the linear functions, we have that both snowman's will have the same height of 21 inches after 5 hours.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we have that:

The initial height is the intercept.

The melting rate, as a negative, is the slope.

Hence the functions are given as follows:

A(t) = 51 - 6t.

B(t) = 36 - 3t.

The functions are graphed at the end of the answer, with <u>A(t) in red and B(t) in blue,</u> and they intersect at (5,21), meaning that both snowman's will have the same height of 21 inches after 5 hours.
