Answer:
interest

Answer:
5 days
Step-by-step explanation:
We can use a ratio to solve
12 emails 60 emails
--------------- = --------------
1 day x days
Using cross products
12*x = 1 * 60
12x = 60
Divide each side by 12
12x/12 = 60/12
x =5
It will take him 5 days
Answer:
(-24, -8)
Step-by-step explanation:
Let us recall that when we have a function f

<em>if the gradient of f at a given point (x,y) exists, then the gradient of f at this point (x,y) gives the direction of maximum rate of increasing and minus the gradient of f at this point gives the direction of maximum rate of decreasing</em>. That is

at the point (x,y) gives the direction of maximum rate of increasing

at the point (x,y) gives the direction of maximum rate of decreasing
In this case we have

and we want to find the direction of fastest speed of decreasing at the point (-3,-2)

at the point (-3,-2) minus the gradient equals

hence the vector (-24,-8) points in the direction with the greatest rate of decreasing, and they should start their descent in that direction.
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
