Answer:
9/2
Step-by-step explanation:
m=∆y/∆x
m= (5+4)/(2—0)
m=9/2
The slope-intercept form: y = mx + b
(m - slope, b - y-intercept)
We have y = -2. It's the slope intercept form where m = 0 and b = -2.
y = -2 → y = 0x - 2
Let's call the number of pages that Jen wrote "j".
then tom (t) wrote:
What we know:
j=10t
this means:
t=0.1 j
and j+t=396
for this it's practical to substitute j with 10 t:
10t+t=396
11t=396
we divide both sides by 11:
t=36
so tom wrote 36 pages, and Jen wrote ten times as much, or 360 pages (that's a lot!)
The answer is 671
3,039/9
671
671*9
3,039
