define the 3 numbers
smallest number = x
middle number = x + 2
largest number = x + 4
write the equation
sum of the smallest number and twice the middle number

20 more than the largest number

equal the expressions

the numbers should be 10, 12 and 14
The function which can represent the height, y according to the horizontal distance, x is; Choice A; y = –3/4x + 36.
Which function can represent the height, y, according to the horizontal distance x, from the top of the stairs?
According to the task content; The railing will begin at a height of 36 inches and follow the slant of the stairs. On this note, it follows that the y-intercept of the function is 36.
Additionally, since the railings decreases 9 inches for every 12 horizontal inches, it follows that the slope, m = -9/12 = -3/4.
On this note, the required function is; A.y = –3/4x + 36

Since line l and line m are cut by the transversal and angle 3 and 5 are supplementary, that means they are consecutive interior angles which proves that the two lines are parallel.
Answer:
Drinks= $3.50 popcorn=$4.25
Step-by-step explanation:
Let medium popcorn=m
Let drinks= d
Equation 1: m+3d=14.75
Equation 2: 2m+5d=26
Solve simultaneous equation
Multiply Equation 1 by 2 and compare to find d
Substitute d into equation 2 to find price of medium popcorn
If
, then by definition of absolute value

On the other hand, if
, then

So, the overall solution to the inequality is interval union
