Answer:
2j-42
Explanation:
The phrase is “42 less than twice Janelle’s age”. Basically, this can be separated into “42 less than” and “twice Janelle’s age”. “Twice Janelle’s age” infers that Janelle’s age is doubled; This can be achieved by 2j because it multiplies Janelle’s age by 2(Times 2 is doubling, times 3 is tripling, and times 4 is quadrupling). The second part is “42 less than” meaning something, in this case Janelle’s age, is subtracted by 42 because less than means negative/minus; This is written as “-42”. So, when we put “42 less than Janelle’s age” together, it becomes -42+2j, which ordered correctly becomes as 2j-42.
Answer:
3^x=9^{x+5}
Step-by-step explanation:
3^x=9^{x+5}
x^2-x-6=0
x^4-5x^2+4=0
\sqrt{x-1}-x=-7
\left|3x+1\right|=4
\log _2\left(x+1\right)=\log _3\left(27\right)
3^x=9^{x+5}
If request to solve;
\mathrm{Convert\:}9^{x+5}\mathrm{\:to\:base\:}3
9^{x+5}=\left(3^2\right)^{x+5}
\mathrm{Solve\:}\:x=2\left(x+5\right):\quad x=-10
