Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.

Let's substitute b-2 into the first equation wherever there is an a.

a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3

Now let's find a by substituting -3 into either of the equations to find the value of a.

a = b - 2
a = -3 - 2
a = -5

So your solution set  is (-5, -3)

Two students in your class, Ralph and Bobby, are disputing a function. Ralph says that for the function, between x = −1 and x =
marshall27 [118]

Answer:

Ralph and Bobby both are correct about slope. Because slope for both is 0.

Step-by-step explanation:

We are given a function that has two values of x's between x = −1 and x = 1.

And the average rate of change between x=-1 and x=1 is 0.

We know that x=-1 and x=1 are the points on x-axis.

If we joint x=-1 and x=1 points, we would get a straight line horizontal line on x-axis.

And note, the slope of a horizontal line is 0 always.

So, according to Bobby the graph goes up through a turning point, and then back down that means the point (-1,0) gets horizontally shift by 2 unit at (1,0).

Therefore, rise/run = 0/2, that is also equal to 0.

Therefore, Ralph and Bobby both are correct about slope.

Because slope for both is 0.
