Which expression simplifies to: 12x−9

(10x−2)−(−2x+7)

(10x+2)−(2x−7)

(7x−5)−(5x−4)

10x−2−2x+7

Ask a tutor on child

Step-by-step explanation:

(10x+2)−(2x−7)

Step-by-step explanation:

(10x−2)−(−2x+7) = 10x−2+2x-7

(10x+2)−(2x−7) = 10x−2−2x+7

(7x−5)−(5x−4) = 7x−5− 5x+4

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

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.
