Expand and simplify: 3 ( g + 5 ) − 3 ( g + 6 )

- 3

distribute each bracket, multiplying the terms in the bracket by the value outside the bracket.

= 3g + 15 - 3g - 18 → ( collect like terms)

=(3g - 3g) + (15 - 18) = 0 + ( - 3) = - 3

3 ( g + 5 ) − 3 ( g + 6 ) =

3g + 15 - 3g - 18

The numbers before the parentheses are multiplied by numbers Inside parentheses

And :

3g - 3g -18 + 15= - 3

3g - 3g are symmetrical and destroy each other

answer: 2 and 1

step-by-step explanation: got this question

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
