Find the y-coordinate of the y-intercept of the polynomial function defined

1 answer:

6 0

The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.

f(0) = 9(0)^2 - 7 - 8(0)

f(0) = -7

Therefore the “y” coordinate would be -7

The ordered pair would be

(0, -7)

The distance between town X and town Y is 124 kilometres and a car uses 25 litres of petrol to make the journey. after the engin

Jlenok [28]

Answer:

49 litres of petrol are needed to travel from town X to town Y and back.

Step-by-step explanation:

Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.

25L of p (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less p than before it was tuned.

2%/100 = 0.02

0.02 * 25L = 0.5L

25L - 0.5L = 24.5L

Now, don't forget, at the end of the word problem we're asked how many litres of p would be required to travel from x to y AND BACK. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)

Good luck!!
