The product of two integers is 112 . one number is four more then three times the other . which of the following equations could be used to find one of the numbers ? a. 3x^2+4x=112 b. 4x^2+3=112 c. 4x^2+3x=112 d. 3x^2+4=112

x, y - two integers

the product of two integers is 112

(1)      xy = 112

one number is four more then three times the other

(2)     y = 3x + 4             substitute it to (1)

x(3x + 4) = 112      use distributive property

(x)(3x) + (x)(4) = 112

3x² + 4x = 112

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.

ab will be equal to
