2(3x-5)+4x-10=4x+2(x+6)

x= 8

Step-by-step explanation:

2(3x-5)+4x-10=4x+2(x+6)

Cancel equal terms on both sides of the equation

2(3x-5)-10= 2(x+6)

Distribute 2 through the parenthesis

6x-10-10= 2x+12

Calculate the difference

6x-10-10= 2x+12

6x-20= 2x+12

Move variable to the left-hand side and change its sign

6x-20= 2x+12

-2x        -2x

4x-20= 12

Add 20 to both sides.

4x-20= 12

  +20 +20

4x= 32

Divide both sides of the equation by 4

4x= 32

4     4

x= 8

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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.
