Step-by-step explanation:
f(x)=(x-5)(5x +2)=0
=> x=5 or, x=-2/5
smaller x = -2/5
larger x=5
Answer: What is the question????
2(4z-3-21)=166-46
Combine like terms
2(4z-24)= 120
Distribute
8z-48= 120
Add 48 to both sides
8z= 168
Divide both sides by 8
z=21
Final answer: z=21
Answer:
7.429 cents
Step-by-step explanation:
Given that:
Price change = $1.51 to $2.03
Period of time = 7 years
Therefore, the annual inflation rate :
Difference in price / number of years
($2.03 - $1.51) / 7
$0.52 / 7
= 0.0742857 per year
= 0.0742857 * 100 (about 7.429 cents per year)
Answer:
3440
Step-by-step explanation:
The total number of people polled is 150.
The total number of people who said they'd vote for Candidate #2 is 78.
The number of undecided voters is 7.
Assuming undecided voters don't vote, Candidate #2 can expect to win 78/143 = 54.5% of the votes.
75% of the 8400 registered voters will vote, or 6300.
So Candidate #2 can expect to win 3440 votes.
