A function works like this:
You put any number you want into the input, and
the output depends on the number you put it.
That's why the output is the dependent variable.
Answer:
0.75 was how much she paid for each postcard.
Step-by-step explanation:
6.04-3.79
=2.25
so take 2.25 divided by 3
= o.75
equations would be 6.04-3.75=b/ 3
Answer:
2. 94.0 km/h
Step-by-step explanation:
since the airplane is moving at angle of 54° from the ground, the horizontal component of the velocity is given by cos component
speed of air plane= 160 km/hr
horizontal component of velocity v= 160 cos 54°
= 94.045 km/hr
Thus the truck must travel at an speed of 94.0 Km/hr hence second option is correct.

I'm assuming you're referring to problem 6. You are asked to find the number of x intercepts or roots, which is another term for "zero". I prefer the term root or x intercept as "zero" seems misleading. Anyways, all we do is count the number of times the graph crosses the x axis. This happens 4 times as shown in the attached image below. I have marked these points in red. The graph can directly cross over the x axis, or it can touch the x axis and then bounce back. Either way, it is considered an x intercept.
<h3>Answer: there are 4 x intercepts (or 4 roots)</h3>
