Answer:

True

Step-by-step explanation:

To determine if (5, - 2 ) is a solution to the system , substitute the values of x and y into the left side of both equations and if equal to the right side then it is a solution.

5(5) - (- 2) = 25 + 2 = 27 = right side

- 3(5) + 4(- 2) = - 15 - 8 = - 23 = right side

the point (5, - 2 ) makes both equations true then is a solution to the system.

A rack of 15 billiard balls is shown. If one ball is selected at random, determine the odds against it containing a number grea

andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

A probability is the number of desired outcomes divided by the number of total outcomes.
An odd is the number of desired outcomes divided by the number of non-desired outcomes.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, 6 are less than 7(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

There are 6 desired outcomes.
There are 9 non-desired outcomes.

The odd is:

$\frac{6}{9} = \frac{2}{3}$

The odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

Y=-3 - x, how to draw the graph

adell [148]

Answer: See attachment below (graphing)

Step-by-step explanation:

INFORMATION:

The slope-intercept is when y=mx+b

mx=the slope

b=y-intercept

REPHRASE EQUATION:

y=mx+b

y=-3-x

y=(-1)x-3

CONCLUSION:

Slope=-1

Y-intercept=-3

Hope this helps!! :)

I need to find X but I don't know how to do it

klio [65]

I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185
