Answer:
x = 14
Step-by-step explanation:
Given
-
(x - 4) = - 2
Multiply both sides by 5 to eliminate the fraction
- (x - 4) = - 10 ← distribute parenthesis by - 1
- x + 4 = - 10 ( subtract 4 from both sides )
- x = - 14 ( multiply both sides by - 1 )
x = 14
I'm going to try to do it in shorter time without calculator
cone is used to fill cylinder
conevolume times x=cylindervolume
so
x=cylinderv/conev
cylinderv=hpir^2
conevolume=1/3hpir^2
cylinder:
v=hpir^2
r=10
h=20
v=20*pi*10^2=2000pi
cone=1/3hpir^2
r=5
h=10
v=1/3(10)pi5^2=250pi/3
vcylinder/vcone=2000pi/(250pi/3)=6000pi/250pi=600/25=24
answer is 24 times

<span>x y + p = 9
subtract p on both sides
xy + p - p = 9 - p
simplify
xy = 9 - p
divide both sides by x
xy/x = (9-p)/x
simplify
y = (9 - p)/x

Where’s the picture, if you had a picture i could help you :)
Set the equation equal to 0
The zeros are {0,-2,-3}
