I believe it is the second option.

Hope this helps :)

That would be the second choice:- 3 maps to 2 and to 1 so its not a function.

S=a+(n-1)d,solve for d

Vinvika [58]

Answer:\frac{s-a}{n-1}

Step-by-step explanation:

formula, s=a+(n-1)d

1. get rid of the a on d's side by subtracting it from both sides.

s=a+(n-1)d becomes s-a=(n-1)d

2. get rid of (n-1) by dividing it from both sides. s-a=(n-1)d becomes

\frac{s-a}{n-1} =d

Jessica Reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time that it takes the turtle to swim

Zigmanuir [339]

Answer:

Time (secs) => distance (ft)

1 => ⅔

15 => 10

24 => 16

45 => 30

Step-by-step explanation:

Equation to represent this proportional relationship is $d = tk$ , where,

t = time

d = distance

k = constant of proportionality

To complete the table, let's find k given that the turtles swarm 16 ft (d) in 24 secs (t).

Substitute d = 16, t = 24 into the equation.

$d = tk$

$16 = 24k$

$\frac{16}{24} = k$ (division property of equality)

$\frac{2}{3} = k$

Let's complete the table by substituting the value of k and the other given value of t or d, as the case may be:

For 1 sec, let's find distance (d):

$d = tk$

$d = 1*\frac{2}{3}$

d = ⅔ ft

For 10 ft, let's find the time (t) taken:

$d = tk$

$10 = t*\frac{2}{3}$

Multiply both sides by 3

$10*3 = t*\frac{2}{3}*3$

$30 = t*2$

Divide both sides by 2

$\frac{30}{2} = \frac{t*2}{2}$

$15 = t$

t = 15 secs

For 45 secs, let's find distance (d):

$d = tk$

$d = 45*\frac{2}{3} = 15*2$

d = 30 ft

Is the sum of a negative and positive number always negative

Semenov [28]

No because if you do -5+10= it equals positive 5 and not a negative number.
