So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.

So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.

f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10

6 - x coordinate, 2 - y coordinate.

6 > 0, then we need to move right 6 points. 2 > 0, than we need to move up 2 points

What is the rate of change of the cost with respect to the number of miles for the Yellow Cab Company?
Leona [35]

Answer:

$2/mile

Step-by-step explanation:

Look at the graph.  We see that two points on this line are (0, 2) and (9, 20).

The "run" is (9 - 0), or 9, and the "rise" is (20 - 2), or 18.

The slope of this yellow line is thus m = rise / run = (18 dollars) / (9 miles) = $2/mile

This slope of the yellow line is the incremental taxi fare per mile traveled and is speed of the car and is m = 2 mph.

Answer:

m∠WXY = 135°

Step-by-step explanation:

An Exterior Angle is the angle formed between a side and a line extended from the next side.

The Exterior Angle theorem says that an exterior angle's measure is the sum of its two remote interior angles (the two angles that are opposite of the angle).

In this example, ∠WXY is the exterior angle, and the remote interior angles are ∠Z and ∠Y.

So,

m∠WXY = m∠Z + m∠Y

m∠WXY = 73° + 62°

m∠WXY = 135°
