Hi there!

nickels:19

We know that there is only nickels and dimes in his coin collection..

<u><em>1.Multiply two terms:</em></u>

<u><em /></u>10<u><em>·</em></u>10=1.00<u><em /></u>

<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>

<u><em>2.Multiply the terms:</em></u>

<u><em /></u>11<u><em>·</em></u>10=1.10<u><em /></u>

<u><em /></u>19<u><em>·</em></u>5=0.95<u><em /></u>

<u><em>3.Combine the two terms:</em></u>

<u><em /></u>1.10+0.95=2.05<u><em /></u>

Therefore, there would be 19 nickels...

<u><em /></u>

Determine which consecutive integers do not have a real zero of between them. a. (–6, –5) c. (–2, –1) b. (–5, –4) d. (1, 2) Plea
svetoff [14.1K]
We have by the intermediate value theorem that if a continuous function takes values both above and below zero at 2 points, there is a zero of the function in-between. We have that polynomials are continues. Let's calculate f(-6) and f(-5). f(-6)=-36 while f(-5)=-1. Thus, we cannot conclude that there is a root between them.
F(-2)=8, f(-1)=-1, so there is a flip; a zero must exist between them.
F(1)=-1, f(2)=20, so again there is a change of signs.
f(-5)=-1, f(-4)=14 so there is a root still.
We have that the only choice that does not have a root between the integers is choice a.

Write the following expression using the fewest possible terms.<br><br> (−2x − 13) + (19 + 5x)
MakcuM [25]

The rewritten form of the given expression using the fewest terms is; 3x + 6.

<h3>What is the rewritten form of.the expression using the least possible terms?</h3>

It follows from the task content that the given expression is to be rewritten using the fewest terms.

Since the given expression is;

( −2x − 13 ) + ( 19 + 5x )

By getting rid of the parentheses; we have;

-2x - 13 + 19 + 5x

By collecting like terms; we have;

-2x + 5x - 13 + 19

3x + 6

Therefore, the required rewritten form of the given expression is; 3x + 6.
