What is Another way to write -35/-7

How many ways are there to select 12 countries in the United Nations to serve on a council if 3 are selected from a block of 45,

sattari [20]

Answer: There are 2346953264 ways to do so.

Step-by-step explanation:

Since we have given that

Total number of selected countries = 12

Number of selected countries from a block of 45 = 3

Number of selected countries from a block of 57 = 4

So, remaining number of selected countries from a block of 69.

So, 12-(3+4)=12-7=5

Now, we need to find the number of ways, so we will use "Combination" to select that number of countries.

So, it becomes.

$^{45}C_3\times ^{57}C_4\times ^{57}C_5\\\\=14190\times 395010\times 4187106\\\\=2346953264$

Hence, there are 2346953264 ways to do so.

Two numbers, a and b, have a sum of 24. The

mina [271]

Answer:

a= -12 and b=36

Step-by-step explanation:

a+b=24 and 3a+b

a-3a+b=24

-2a+b-b=24

-2a/-2=24/-2

a= -12

then substitute the value of a in a+b=24 to get the value of b

so let see -12+b=24

b=24+12

b=36

we can check it by the equation -2a+b-b=24

-2(-12)+36-36=24

24=24 so as you have seen the answer is correct

thanks!!!

PLEASE HELP ME WITH THIS KHAN ASAP I did 5 hours of Khan :(

Nuetrik [128]

Answer:

The functions have the same y-intercept.

OPTION C is correct.

Step-by-step explanation:

DEFINITIONS AND FORMULAS

The equation of a linear graph is given to be:

$y=mx+b$

Where m is the slope of the graph and b is the y-intercept.

To calculate the slope given a table, we can use the formula:

$m=\frac{y^{2}-y^{1} }{{}x^2 -x^1}$

SOLUTION

Function 1: The equation of the graph is given to be

$p=-\frac{3}{2}r-5$

Therefore, the y-intercept of the graph is given to be:

$b=-5$

Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.

On checking the graph, we can see that when r = 0, p = -5.

Therefore, the y-intercept is:

$b=-5$

ANSWER

The functions have the same y-intercept.

OPTION C is correct.
