Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero
Answer:
360
Step-by-step explanation:
12 x 10 = 120 (Bottom face)
10 x 5 = 50 (left face)
13 x 10 = 130 (side face)
6 x 5 = 30 (triangle)
6 x 5 = 30 (other triangle)
Add all those to get an answer of 360
Answer:
1300 + 45x
Step-by-step explanation:
i hope this helps
If you are trying to solve for x, then
4x+5<=13
subtract both sides by 5
4x<=8
then divide both sides by 4
x<=2
