Answer:
Step-by-step explanation:
9x*(9x - 32) = (9x- 24)²
9x*9x - 9x*32 = 81x² - 2*9x*24 + 576
81x² - 288x = 81x² - 432x + 576
81x² - 288x - 81x² + 432x - 576 = 0
81x² - 81x² - 288x + 432x - 576 = 0
144x - 576 = 0
144x = 576
x = 576/144
x =4

Answer:
The solution is represented by the first number line, wich has the solutions x=-6 and x=-2.
Step-by-step explanation:
We have an absolute value function for the equation. This means that we should have two differents solution in the real number line. As the equation is
when we clear out the absolute value, we will have two possible solutions:
and
now we clear x from both equations
Then, we have that x=-2 and x=-4 are the solutions for the equation, and therefore the number line that represents the solution is the first one, where the points -6 and -2 are highlighted.
the first number line
given | x + 4 | = 2
removing the bars from the absolute value gives
x + 4 = 2 or x + 4 = - 2
x = 2 - 4 or x = - 2 - 4
x = - 2 and x = - 6 ← solutions
these are indicated on the number line by a solid circle at - 2, - 6
Answer:
0.001
Step-by-step explanation:
Here, the aim is to support the null hypothesis, Ha. Where Ha: p > 0.5. Which means we are to reject null hypothesis H0. Where H0: p = 0.5.
The higher the pvalue, the higher the evidence of success. We know If the pvalue is less than level of significance, the null hypothesis H0 is rejected.
Hence the smallest possible value 0.001 is preferred as the pvalue because it corresponds to the sample evidence that most strongly supports the alternative hypothesis that the method is effective
Answer:
B1: +6 (to get to plus six you would have to pass negative one so really it's seven)
B2: they are the same distance
B3: -7
B4: +7
<3 have a good day :)
Step-by-step explanation:
Answer:
hope this helped! Can I get brainliest? :)) please?
Step-by-step explanation:
1. +6 is the answer because it is 8 units away from -2
2. both are the same distance from -2
3. -7 is the answer because it is 5 units away from -2
4. +7 is the answer because it is 9 units away from -2
Answer:
Mark 2
Step-by-step explanation:
There are 40 marks on the lock.
Every full turn of 40 marks, the lock will come back to mark 19.
137/40 = 3R17
You can make three full turns (which is equivalent to doing nothing), and then you must move 17 more marks.
19 - 17 = 2
The lock will be at mark 2.
If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark 2.
Combination lock is opened by rotating a set of number dials or marks graduated in a sequence.
The marks on a combination lock are numbered 0 to 39. If the lock is at mark 19, and the dial is turned one mark clockwise, it will be at mark 18. If the lock is at mark 19 and turned 137 marks clockwise,
137 = 40a +b where b<40
Divide 137 by 40, so we get the quotient 3 i.e., a =3.
Substitute a = 3 , the value of b is
b = 17
If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark,
19-17 = 2
Thus, If the lock is at mark 19 and turned 137 marks clockwise, it will be at mark 2.
