Answer:
i have done the cutting of x's exponent
Step-by-step explanation:
= 3x - 30+9 =0
= 3x - 21 =0
= 3x= 21
= x = 21/3
x= 7 this the answer
Answer:
The first question is (n*8) - 4
The second question is no.
Step-by-step explanation:
The first question, you add 8. The first is 1. 1 * 8 = 8 - 4 = 4.
Therefore, the equation is (n*8) - 4
The second question, you can plug in numbers. You can solve for a term. -100 + 17 = -83. -83 is not a multiple of -4. -100 is not a term.
Answer:
0.6708 or 67.08%
Step-by-step explanation:
Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:

There is a 0.6708 probability that Helen makes both free throws.
The answer you want would be -120
b/c 200/5 is 40 so -3*40 is <em>-120</em>
