Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

Lubov Fominskaja [6]

<u>Answer:</u>

First car: 35 gallons

Second car: 15 gallons

<u>Step-by-step explanation:</u>

Assuming $x$ to be the gas consumed by 1st car and $50 - x$ to be the gas consumed by 2nd car.

We know that:

Distance traveled = fuel efficiency × gas consumed

$20x+35(50-x)=1225$

$20x+1750-35x=1225$

$35x-20x=1750-1225$

$15x=525$

$x=35$

So $50 - x = 50-35=15$

Therefore, first car consumed 35 gallons while second car consumed 15 gallons.

Answer:

b ≈ 48.6°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin b = $\frac{opposite}{hypotenuse}$ = $\frac{9}{12}$ , then

b = $sin^{-1}$ ( $\frac{9}{12}$ ) ≈ 48.6° ( to 1 dec. place )
