A line passes through the points (4,6) and (6,2) .
siniylev [52]
ANSWER

Yes

No

No

Yes

EXPLANATION

The given line passes through the points,.
(4,6) \: and \: (6,2)

We need to determine the slope of this line using these two points.

The formula for finding the slope is

m=\frac{y_2-y_1}{x_2-x_1}

m = \frac{2 - 6}{6 - 4} = - \frac{ - 4}{2} = - 2

We can now use the formula

y-y_1=m(x-x_1)
in the slope intercept form.

If we use the point
(4,6)
the equation will be,

y - 6 = - 2(x - 4)

If we use the point,

(6,2)
we obtain,
y - 2 = - 2(x - 6)

There are (n r) different linear arrangements of n balls of which r are black and n-r are white. give a combinatorial explanatio
Vanyuwa [196]

Answer:

\frac{n!}{r!(n-r)!}

Step-by-step explanation:

Combinatorial explanation:

The n balls have to be arranged in n positions and the only distinction is where are the black and where white balls are.

We can choose the position of black balls in \binom{n}{r} ways, therefore, white ones are on the remaining positions.

Using binomial we can have explanation written below:

The balls can be arranged in n! possible permutations.

To be precise one particular arrangement includes r!(n-r)! permutations. Since r black balls can be permuted in r! ways and white balls in (n-r)! different orders.

So basically it yields,

r! \times (n-r)! permutations.

So the actual amount is,

\frac{r!}{(n-r)!}= \binom{n}{r}=\binom{n}{n-r}

The area of a square is 8 square meters. Which of these
Blizzard [7]

Answer:

G.

Step-by-step explanation:

Length = Square root of Square area

= √8 (-√8 is rejected as length is positive)

We know that √4 < √8 < √9 because 4 < 8 < 9.

=> 2 < √8 < 3.

The only answer that is in this range is G.

I really need help please!! <br><br> Please show work!! Will mark brainliest!!
Setler [38]

Answer:

A) Lifetime: 200+15x

Health Bridge: 50+30x

B.1) Yes, they are both the same price after 10 Months at an amount of $350

B.2) Lifetime gym would be cheaper by $30

C) Health Bridge Gym because it is $60 less

D) Lifetime Gym

Step-by-step explanation:

A) 200=Initial Fee___15=Monthly Cost___x=Months

50=Initial Fee___30=Monthly Cost___x=Months

--------------------------------------------------------------------------------------------------------------

B.1) 200+15(10)=350

50+30(10)=350

--------------------------------------------------------------------------------------------------------------

B.2) 200+15(12)=$380

50+30(12)=$410

--------------------------------------------------------------------------------------------------------------

C) 200+15(6)=290

50+30(6)=230

--------------------------------------------------------------------------------------------------------------

Lifetime Gym's initial fee is greater than Health Bridge's fee but without exceeding $500, you are able to go to the gym for 20 months rather than 15 months using Health Bridge's plan.

D)200+15(20)=$500

50+30(15)=$500

--------------------------------------------------------------------------------------------------------------

I hope this is enough work shown, if you need a better understanding let me know and I will revise the equations for you.
