6, 9, then 18. Just add 3 every time because it is asking how much it increases. For the first one you multiply it by 2 (2h) which got 6, for the second you multiply it by 3 (3h), and for the last one you multiply it by 6 (6h) which got 18.

<em>it increases 3° each hour</em>

3*2= 6

6° after 2 hours

3*3= 9

9° after 3 hours

3*6= 18

PLSS HELPP BRAINLIEST AND 65 POINTS <br> pls do the graph too

Eddi Din [679]

Answer:

$\Large \boxed{ -x+65}$

Step-by-step explanation:

Two points are (0, 65) and (10, 55)

Calculate slope <em>m</em>

$\displaystyle m=\frac{y_2 - y_1}{x_2 - x_1}$

$\displaystyle m=\frac{55-65}{10-0}=-1$

Use slope-intercept form

$y=mx+b$

$y=-1x+b$

<em>b</em> is the y-intercept, y-intercept is (0,65)

$y=-1x+65$

Four notebooks 4.40. how many notebooks can you buy for 6.60.

denis23 [38]

We know we have $4.40 for 4. Divide 4.40 by 4, you get 1.10. So it's $1.10 per notebook. Therefore, divide 6.60 by 1.10. You get 6, so you can get six notebooks with $6.60.
Hope this helps!

HELP PLS!!! find x and y please show steps

loris [4]

Answer:

Step-by-step explanation:

The sum of measures of angles in triangle is 180°

so:

180° - 90° - 45° = 45°

two angles angles of the same measure, that means: x = 7

so:

$7^2+7^2=y^2\\\\y^2=7^2\cdot2\\\\y=\sqrt{7^2\cdot2}\\\\\bold{y=7\sqrt2}$
