Solve the equation.

3(2x+5)=-6=9

What does x equal?

x = -2

Step-by-step explanation:

Expand:

6x + 15 = -6 + 9

6x + 15 = 3

Put 15 on the other side

6x + 15 - 15 = 3 - 15

6x = -12

x = -2

-2

Step-by-step explanation:

3(2x+5) =-6 +9

6x +15 =3

6x=3 - 15

6x =-12

x=-12:6

x=-2

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
