6x-15=3(4x+3)
Distribute the three to the parentheses
6x-15=12x+9
Transfer the 6 over to the 12 by subtracting it
-15=6x+9
Subtract 9 from 15
-24=6x
Then divide the six by the -24
X=-4

6x - 15 = 3(4x + 3)
then you distribute the three
so you would do
3 \times 4x = 12x
3 \times 3 = 9
6x - 15 = 12x + 9
then you get the variables on the same side
- 6x
on each side so you would have 6x on the right side then you subtract the nine so you would have -24 on the left side so now you have
- 24 = 6x
then you divided by 6 which the answer equals
x =  - 4

Find the slope of the given points (3, 4) and (7,-4).<br> A)-1/2<br> B) 2<br> C) -2<br> D) 0
kakasveta [241]

Answer:

-2

Step-by-step explanation:

y = kx + n

When you insert the given points you get

3k + n = 4 \\

7k + n =  - 4 \\

Than you multiply the first one by - 1 and sum it with the second to get rid of n

4k =  - 8 \\ k =  - 2

10. Suppose y varies directly as x, and y = 9 when x = 3/2. Find y when x = 1
pogonyaev

Answer:

y = 6

Step-by-step explanation:

We need to interpret the question

y varies directly as x

y varies x

To equate it, we need to add a constant K

y = K/x

Using the information we are provided with

y = 9

x = 3/2

insert into

y = Kx

9 = K * 3/2

9 = 3K/ 2

3K = 9 *2

3k = 18

To get K, divide through by 3

3K/3 = 18/3

K = 6

Since we've gotten our K = 6

y = Kx

Using the new information

y = ?

x = 1

K = 6

y = 6* 1

y = 6

The new y = 6 , x =1
