Answer:
c. Both m(x) and p(x) have the same output value at x = 7.
Step-by-step explanation:
For input value x, m(x) is the output value.
m(7) is the output value of the function m(x) when x=7.
p(7) is the output value of the function p(x) when x=7.
The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.
Answer: (Z-4)/12
Step-by-step explanation:
(Z-4)/(4+8)
4+8 equals 12
(Z-4)/12
The correct answer is A) $75.85.
A discount of 20% means that the cost is 80% of the original. 80%=80/100=0.8
0.8(129) = 103.20
A discount of 30% means that the cost is 70% of the amount before discount. 70%=70/100=0.7
0.7(103.20) = 72.24
A sales tax of 5% means that it is 105% of the amount pre-tax. 105%=105/100=1.05
1.05(72.24) ≈ 75.85
Answer:
You need 30 total weeks to win at least 65% games
Step-by-step explanation:
Team have played = 20 games
Number of winning games = 3
Let x represents the number of additional weeks.
You have won 3 games per week. Therefore you will win 3x additional games.
We know that 65% = 0.65
Therefore,
3+3x/20+4x = 0.65
By cross multiplication:
3+3x= 0.65(20+4x)
3+3x = 13+2.6x
Combine the like terms:
3x-2.6x = 13-3
0.4x=10
4x/10 =10
4x = 10*10
4x=100
Divide both sides by 4
4x/4 = 100/4
x = 25
since you have already played 5 weeks...you need to play 25+5 = 30 weeks.
Therefore you need 30 total weeks to win at least 65% games....
