2. The speed limit on a city street is 35 kilometers per hour. Write and graph an inequality to describe a car’s possible speed.

where denotes speed of the car

Step-by-step explanation:

Given: The speed limit on a city street is 35 kilometers per hour.

To write and graph: an inequality to  describe a car’s possible speed.

Solution:

Let the speed of a car be kilometers per hour.

As the speed limit on a city street is 35 kilometers per hour,

First draw the graph of (see figure a.)

Plot the points

Take a point on the left side of line x = 35 say and put it in

which is true.

So, shade the graph on the left side of line x = 35

See the graph b.

the pink part represents the inequality

answer: i think it's a

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
