What is one possible value for the sum of the values of x that satisfy the equation 2x^2 + 3x - 28 = 0 ? A) -5
B) -4
C) -3
D) -2

the first one, all those points on the line just make a strait line.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

the square root of 16 is 4.

4*4 = 16
