Answer:

7. 15.5

8. 12

Step-by-step explanation:

Question 7 equation: \frac{3*1}{2} + \frac{5+2}{2} * 4=1.5 + 3.5 * 4 = 1.5 + 14 = 15.5.

Question 8 equation: (\frac{2*2}{2} * 2) + (\frac{4*2}{2} *2) = 4 + 8 = 12.

For which equations below is x = –3 a possible solution? Check all that apply.
Fiesta28 [93]
|x|=3, |-x|=3, -|x|=-3. You can check each of the options one by one. First notice that the absolute value of some number can never be negative, so eliminate b, d and f. |-3|=3. |-(-3)|=|3|=3. -|3|=-3. So these three solutions are all correct answers.

Solve xy^m=yx^3 for m
aleksklad [387]

Answer:

  m = 1 + 2log(x)/log(y)

Step-by-step explanation:

Taking logarithms, you have ...

  log(x) +m·log(y) = log(y) +3log(x)

  m·log(y) = log(y) +2·log(x) . . . . subtract log(x)

  m = (log(y) +2·log(x))/log(y) . . . divide by the coefficient of m

  m = 1 +2·log(x)/log(y) . . . . . . . simplify a bit*

_____

* The "simplified" form will depend on your preference. Here, I like the integer 1 brought out because most logs are irrational. The result may be very slightly more accurate if we add 1, rather than log(y)/log(y)--depending on your calculator.
