The sum of twice a number x and 13 is two less than three times x

This is a word problem which requires basic logic or understanding to solve. We can write the equation:

2 x + 13 = 3 x – 2

So calculate for x:

3 x – 2x = 13 + 2

x = 15

Therefore the number is 15.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

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.
