ANSWER

point C

EXPLANATION.

$- \frac{5}{4} = - 1.25$

-1.25 is less than -1 but greater than negative -2.

On the number line, -1.25 is closer to -1 than to -2.

From the graph, point C is between -2 and -1 but closer to -1.

Therefore

$- \frac{5}{4}$

is represented by point C on the number line .

Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold

Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1), we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y = 16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:

Complete the table of values for the function f(x) = (1/3)x for a, b, and c. x : -2, -1, 0, 1, 2. f(x) : a, b, c, 1/3, 1/9

balu736 [363]

Given:

The function is

$f(x)=\left(\dfrac{1}{3}\right)^x$

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,

$f(x)=\left(\dfrac{1}{3}\right)^x$

At x=-2,

$f(-2)=\left(\dfrac{1}{3}\right)^{-2}$

$a=\left(3\right)^{2}$ $\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right]$

$a=9$

At x=-1,

$f(-1)=\left(\dfrac{1}{3}\right)^{-1}$

$b=\left(3\right)^{1}$ $\left[\because \left(\dfrac{a}{b}\right)^{-n}=\left(\dfrac{b}{a}\right)^{n}\right]$

$b=3$

At x=0,

$f(0)=\left(\dfrac{1}{3}\right)^{0}$

$c=1$ $\left[\because a^0=1, a\neq 0\right]$

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.
