Answer:
C i am pretty sure
Step-by-step explanation:
Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.
the line crosses the y axis at -1
B is the option that ends with -1
therefore your answer is B. y = -2x - 1
6x54= 324
6x50=300
6x4=24
300+24=324
The previous nearest cube root is 216 and the next cube root would be 343.
p/q could be any prime number which there are a lot of.
im going to say p is 1 and q is 3
next you would divide 1 by 3
1/3=0.666666667
324x0.666666667=216 exact
Hello from MrBillDoesMath!
Answer:
Take you pick below! (either x 8 or x = 7.01, approx, depending how the question is interpreted)
Discussion:
Interpretation 1
If the question is
2^(x -1) = 128, then as 2^7 = 128,
x-1 = 7 so x = 8
Interpretation 2
If the question is (2^x -1) = 128, then..
2^x = 128 + 1 = 129 =>
log(2^x) = log(129) =>
xlog(2) = log(129) =>
x = log (129) / log2 = 7.01

MrB
