Directions: Solve I think you cross multiply but I'm not really sure where to go from there.

1 answer:

7 0

I'm fairly sure they want you to cross multiply then graph. This will give you 'zeroes' which are solutions for x
if you graph (4x^3+3x^2)= z it'll give you a zero at -0.75 which means x= -3/4

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.

andrey2020 [161]

Answer:

Hey! The answer is 25,4 centimeters.

Step-by-step explanation:

In a linear function you can use y=mx+n

So if x = hours and y= height.

You know that

$\left \{ {{27,8=11m +n} \atop {24,8=26m +n}} \right.$

So:

If you multiply (24,8=26m +n) x-1

It is: -24,8 = -26m -n

Adding up the other equation

-24,8 = -26m -n

27,8 = 11m + n

3 = -15m

m= -0,2

27,8 = 11 x 0,2 + n

27,8 = -2,2 + n

30 = n

This results that te linear function for this equation is:

y = -0,2x + 30

The answer is

y=23(-0,2) + 30

y=-4,6+30

y=25,4
