Zero product says that if you have
x=0, then the non-zero factors equal zero
so
try to move all to one side to get it to equal zero and factor
4y^3-4=y-16y^2
add 16y^2 to both sides
4y^3+16y^2-4=y
subtract y
4y^3+16y^2-y-4=0
gropu and factor
(4y^3+16y^2)+(-y-4)=0
(4y^2)(y+4)+(-1)(y+4)=0
reverse distribute
ba+ca=a(b+c)
(4y^2-1)(y+4)=0
set each to zero
4y^2-1=0
add 1
4y^2=1
divide by 4
y^2=1/4
square root both sides
y=+/-1/2
y+4=0
minus 4
y=-4
y=-4,-1/2,1/2
answer is A -4,-1/2,1/2
Answer:
YOU ADD UP ALL THE DECIMALS
Step-by-step explanation:
1st change 1 5/6 into a mixed number:
1 5/6 = 11/6
New problem:
8/10 divided by 11/6
to divide fractions you turn the 1st fraction upside down and then change the division sign to a multiplication sign:
8/10 / 11/6
10/8 * 11/6
=55/24 or 1 7/24
Answer:
Solve for
x
by simplifying both sides of the equation, then isolating the variable.
Step-by-step explanation:
is this solve for x? you can just tell me what you are doing with this ex: adding, etc
Answer:
Machine 1: 165
Machine 2: 210
Step-by-step explanation:
Machine 1: 11 bottle per minute
11 * 15 = 165 labeled bottles per minute
Machine 2: 14 bottles per minute
14*15 = 210 labeled bottles per minute
