Linear functions increase/decrease at a constant rate as time passes. Exponential functions increase/decrease at a faster and faster rate as time passes.

1) From both tables, you can see that the y-value is going up as the x-value increases. Also notice that the y-value in Set A increases by 25 for each x-value. That means Set A is a linear function, since the rate of increase is the same, 25. Set B doesn't increase by 25 each time, meaning it's rate is different from A, letting you eliminate answers B and C.

2) Now you're left with answers A and D. Set A is linear and Set B is exponential, and from the table, you can see that Set B increases faster than Set A (Set B goes from y=0.6 to y=375 from x=-1 to x=3, while Set A only goes from y=50 to y=150). That means the answer must be choice A.

A) Set B is an exponential function and the values increase at a faster rate than Set A.

Answer from: Quest

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
