Multiply the bracket by -4

-4(3x-2)= 6x+2

-12x+8=6x+2

Whenever multiplying a - negative number and a + positive number = - negative number

Whenever multiplying a - negative number and - a negative number = +positive number

-12x+8=6x+2

Move +6x to the other side. Sign changes from +6x to -6x

-12x-6x+8= 6x-6x+2

-18x+8= 2

Move 8 to the other side. Sign changes from +8 to -8

-18x+8-8= 2-8

-18x= -6

Divide by -18 for -18x and -6

-18/18x= -6/-18

x= 1/3 and in decimal form : x= 0.33333

Answer : x= 1/3 and in decimal form : x= 0.33333

What are the next two numbers in this pattern?
disa [49]
The answer is A. 243, -729

The pattern of this is that they multiply each number by -3.

3*-3=-9
-9*-3=26
27*-3=-81

-81*-3=243
243*-3=-729

Q # 19. I need your help on this
Komok [63]

Solution:

we have been asked to find a function for the given sitatution

The given situation is

A movie store sells DVDs for $11 each. what is the cost C of n DVDs.

Cost of  1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.

Cost of  1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.

......................................................................................................................

.......................................................................................................................

Cost of  1 DVD is $11, then the cost of n DVDS will be nx11=$11n.

Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.

Hence the correct option is C=11n, Discrete.
