Answer:
84*(1/4)^x
Step-by-step explanation:
84 is the constant as it is the starting amount. However each round (x because the amount of rounds is constantly changing) divides the team by 4 or multiplies by 1/4 (Reciprocal).
So, if you wanted to see if the amount of teams after three rounds you would do:
84 * 1/4 * 1/4 * 1/4. However, any number times itself is an exponent, so we would simplify to 84³. But due to the fact we do not know how many rounds we are going to calculate we change the exponent to x.
1.) the answer would be D
2.) D
C=20+0.07(100)
C=20+7
C=27
3.) B
4y-10=22
+10 +10
4y=32
/4 /4
Y=8
4.)$132
60r+0.06(50r)=p
60(4)+0.06(50*4)=p
120+12=p
132=p
5.) $9.40
7+0.012(10,000-8,000)
7+0.0012(2,000)
7+2.4
9.4
Answer:
x = 6
Step-by-step explanation:
y becomes 4x + 6 due to substitution
4x + 6 = 4x + 6
6 = 6
x = 6
