Answer:

y= x squared.

Step-by-step explanation:

When graphed, the parabola only has an x-intercept at (0,0). Since a root is another word for an x-intercept, it only has one root.

I hope this helps, and I hope you have a good day.

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

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

100 POINTS! PLEASE HELP!

Semmy [17]

Apply angle bisector theorem

$\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}$

$\\ \sf\longmapsto 9x=5(2x-1)$

$\\ \sf\longmapsto 9x=10x-5$

$\\ \sf\longmapsto 10x-9x=5$

$\\ \sf\longmapsto x=5$

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}$

$\\ \sf\longmapsto 4(2.25)=3x$

$\\ \sf\longmapsto 3x=9$

$\\ \sf\longmapsto x=3$

Hope it helps
