Answer:
24
Step-by-step explanation:
360 degrees, so 2+6+5+2=15
360/15=24
n=24
(Note: this is hard to explain without graphing. You might want to graph both of these lines just to make sure I did this correctly. :))
Y = -4(x) is the y = mx + b where m = slope and b = the y intercept.
So the slope of line A is -4 / 1 and the y intercept is 0. (If it's 0 there is no point in writing it down, so it was left out of the equation.)
The slope of line B with be equal to the slope of line A, so we can fill that in our equation. y = -4 x + ??
We know that y increases as x decreases.
Now we just need to scale 8, -3 down until x = 0.
(8 - 4, -3 + 1) = (4, -2)
(4 - 4, -2 + 1) = (0, -1)
y = -4x -1 is your final answer. Hope that helps! :)
Answer:
<em>y = 3x + 5</em>
Step-by-step explanation:
y = mx + b (slope-intercept form)

Slope m = 
y - = m( x - ) (point-slope form of linear equation)
~~~~~~~~~~~~~~~
In one month she completed 5 paintings, so in 6 month she completed 6 * 5 = 30 paintings.
38 - 30 = 8 - that's how many paintings she's still about to complete.
If she can do 5 paintings in one month, she'll do 8 paintings in 1 3/5 months. If we assume that month has 30 days, she'll probalby need one month and 18 days to do it (because 3/5 from 30 is 18).
310 >_ (greater than or equal to) 35x + 9
- 9 -9
301 >_ 35x
/35 /35
8.6 >_ x
Since 8.6 is not a whole number, the answer for the second part is
X<_(less than or equal to) 8
