Add 9 to both ends, simplify 9+9 to 18. Divide both sides by 3. Lastly simplify 18/3 to 6 which leaves x to equal 6

(4,-3),m=-1 in standard form

Kryger [21]

Answer:

Step-by-step explanation:

m = -1 ; ( 4 , -3)

y - y1 = m(x - x1)

y - (-3) = -1(x - 4)

y+ 3 = -x + 4

Add x to both side.

x +y + 3 = 0

Subtract 4 from both sides

x + y + 3 - 4 = 0

x +y - 1 = 0

One rabbit saw six elephants while going to the river. Every elephant saw 2 monkeys going towards the river. Every monkey holds

rodikova [14]

5 animals are going towards the river .

<u>Step-by-step explanation:</u>

Here we have , One rabbit saw six elephants while going to the river. Every elephant saw 2 monkeys going towards the river. Every monkey holds one parrot in their hand.We need to find How many animals are going towards the river . Let's find out:

1 rabbit saw 6 elephants while going to the river. i.e. rabbit is only going towards river !

Every elephant saw 2 monkeys going towards the river. From the sentence , each of the 6 elephants saw 2 monkeys going towards the river, hence will be 6 x 2 = 12 monkeys going towards the river.

But, the statement does not explicitly say that “Every elephant saw 2 DIFFERENT monkeys…”, therefore implicit rules apply and infer that the 2 monkeys are the same. So , every elephant saw 2 monkeys!

Now , every monkey holds 1 parrot in their hands. 2 parrots are going towards the river.

So , total number of animals is :

⇒ $1+2+2$

⇒ $5$

Therefore , 5 animals are going towards the river .

Look at the image for the question. Show all that apply + explanation to help me figure it out better.

OLga [1]

The general point-slope equation for a str. line is y-k = m(x-h),

where m is the slope and (h,k) is a point on the line.

Given that the line passes thru (-4,6) and (1,2), we find the slope as follows:
6-2
m = ----------- = -4/5
-4-1

Subst. -4/5 for m, 6 for k and -4 for h in y-k = m(x-h):

y-6 = (-4/5)(x+4)

Compare this result to the equations given.
