(x,y) or
(x,f(x))
so just plug the first value in and see if yo get the 2nd value
A. when x=-2, then is f(x)=48?
remember, x^-m=1/(x^m)
3(1/4)^-2=3/((1/4)^2)=3/(1/16)=3*16=48
true
B. x^0=1
so 3(1/4)^0=3(1)=3
true
C. when x=2
3(1/4)^2, 3(1/16), 3/16
true
D. 12
das is obviously false but anyway
3(1/4)^12=3(1/big number)=3/big number=small number but not zero
answer is A,B,C
Answer:
5.1
Step-by-step explanation:
I don't know how to explain, but 1 decimal place is the number after the dot
Answer:
19
Step-by-step explanation:
24 * 80% = 24*0.8 = 24* 8/10 = 24*4/5 = 96/5 = 19.2
round down becuase 0.2, or 20% of a person can not earn honor roll without suffering catastrophic organ failure.
y=ax+b
->a= positive (the line is going up)
->to find a, we move one unit horizontally and look over how many units you meet the graph (1 to right, 4 up) so the a= 4
-> to find b, we look for the y-coordinate of the point where the graph and the y-axis cross. they cross in (0,1) so b is 1
when we take this all together we get y=4x+1
