X = 4.326748711
To solve this, raise 3 to the 12th power, and solve for x.
log3(x^9)=12
Take the number in front of the log, 3
Raise it to the number on the other side of the equation, 12
Set that equal to the expression in parentheses
So, we have 3^12=x^9
Solve it like a normal equation by simplifying
3^12= 531441, so
531441=x^9
to get x by itself, take the 9th root of both sides. If you're using a TI-84, you can do this by going to MATH>5 and then typing in the root
x = 4.326748711

Otero translated the phrase "three less than a number" into the expression 3 minus x. Which best describes the accuracy of Otero

fomenos

Correct Question:

Otero translated the phrase "three less than a number" into the expression 3 minus x. Which best describes the accuracy of Otero's expression?.

a. It is accurate. The phrase can be translated as "three" = 3, "less than" = subtraction, and "a number" = X, SO 3- X is the correct expression.

b. It is inaccurate. Three is being subtracted from a number, so X-3 is what he should have written.

c. It is inaccurate. Three is being compared to a number, so 3 It is inaccurate. Three is being added to a number, so 3+ x is what he should have written.

Answer:

The answer is B because three less than a number means that a 3 is less than some number X meaning three is being subtracted from X. So equation should be X-3 rather than 3-X.

HELP NOW PLEASE is say for each pair of angle in parts A thought D estimate the measure of each angle.

Mice21 [21]

Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.

B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.

C: Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.

D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.
