tankabanditka [31]

Answer:

(a) Slope and y-intercept; (b) y = mx; (c) y = x + b

Step-by-step explanation:

1. Need to know

Slope and y-intercept.

You use these numbers to calculate one other point. Then you draw a straight line between the y-intercept and the other point to get the graph.

2. y-Intercept = 0

The form of the equation is y = mx + b, where b is the y-intercept.

If the intercept is zero, b = 0, and the equation has the form

y = mx

The graph is a straight line passing through the origin.

3. Slope = 1

m represents the slope. If m = 1, the equation has the form

y = x + b

If the axes are scaled equally, the graph is a straight line that crosses the y-intercept at an angle of 45°.

At a telethon, a volunteer can take 48 calls over a 4-hour shift. At this rate, how many calls can 12 volunteers take in a 4-hou

stellarik [79]

1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls

The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls

x=12*48=576

So it's 576 hours.

Suppose we have two functions: f(x)=x2+1 and g(x) = 3x +5.<br> Find the value of f(-1)g(-1).

lisabon 2012 [21]

Answer:

-1 x 2 = -2

Step-by-step explanation:

f(-1)=-1 x 2+1 = -1

-1 x 2 = -2

-2 + 1 = -1

g(-1) = 3 x -1 +5 = 2

3 x -1 + -3

-3 + 5 = 2
