Answer:

y = - 9x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - 9, hence

y = - 9x + c ← is the partial equation

To find c substitute (1 , - 8) into the partial equation

- 8 = - 9 + c ⇒ c = - 8 + 9 = 1

y = - 9x + 1 ← equation of line

arlik [135]

Answer:

The ratio that compares the championships won by Australia to the total number won by the United States is equal to $\frac{2}{5}$

Step-by-step explanation:

Observing the graph

we know that

The championships won by Australia are 6

The championships won by the United States are 15

To find out the ratio, divide the championships won by Australia by the total number won by the United States.

$\frac{6}{15}$

Simplify

Divide by 3 boths (numerator and denominator)

$\frac{2}{5}$

Convert to percentage

$\frac{2}{5}=0.40*100=40\%$

that means

For every 2 championships won by Australia the United States won 5

The championships won by Australia are 40% of the championships won by the United States

What is nine plus six divided by (8-2) \

svet-max [94.6K]

Hey there mate ;),

According to given conditions, your question is :

$\frac{9 + 6}{8 - 2}$

So, now calculating,

$\frac{15}{6}$

Now lets solve by reducing to lowest terms,

$→ \frac{15}{6} = \frac{5}{2}$

Now by dividing, we get,

$→2.5$

Therefore, 

$\frac{9 + 6}{8 - 2} = 2.5$
