Is the first step in solving /x- 1 = 8 different from the first step of solving /x (- 1) = 8? Explain -Yes, in the first equation, start by subtracting 8 from both sides to set the equation equal to zero, but in the
second equation, start by adding 1 to both sides to isolate the radical.
Yes, in the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by
adding 1 to both sides to isolate the radical.
No, to solve either equation, square both sides to eliminate all radicals.
No, to solve either equation, isolate the radical by adding 1 to both sides.

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

47

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
