Answer:

x= 1.71

Step-by-step explanation:

We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, - $2^{3x\\}$ =-35. There is a negative sign in both equations so we cancel them out so our equation is $2^{3x\\}$ =35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.

Solve the inequality 171>-6x and graph the solution what does the graph look like

krok68 [10]

To solve the inequality, you need to isolate/get x by itself:

171 > -6x Divide -6 on both sides [dividing/multiplying a negative number on

-28.5 < x [dividing/multiplying a negative number in an inequality causes the sign (<, >, ≤, ≥) to flip]

-28.5 < x [x is a number greater than -28.5]

So your graph should have an open circle at -28.5 (the first small line next to -28), and the arrow pointing to the right since x is greater than -28.5 (increasing) The 1st option is your answer

[use the o---> and put it at -28.5]
