3. 65x5= 325
she traveled 325 feet in 5 minutes
4. 3(6) +5 = 23
6cube - 10 =206
5. area of the triangle is 1/2x base x height
so 1/2 x 15 x 10 = 75
7. they'll have 6 sections. 3/4 divided by 1/8 is 6
hope this helps :)

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
