For
|x|≥y, solve for x such that
x≤-y or x≥y

|y+8|≥3
solve for
y+8≤-3 or y+8≥3
minus 8 from both sides
y≤-11 or y≥-5

the solution set is y≤-11 or y≥-5
basically, all real numbers except z, such that -11<z<-5

the solution set is y≤-11 or y≥-5

Given that y = 18 + 3x²<br> i) express x in terms of y

fgiga [73]

Answer:

$\sqrt{-6 + \frac{y}{3}} = x$

Step-by-step explanation:

y = 18 + 3x²

- 18 - 18

__________

$\frac{-18 + y}{3} = \frac{3x^2}{3} \\ \\ -6 + \frac{y}{3} = x^2 \\ \\ \sqrt{-6 + \frac{y}{3}} = x$

I am joyous to assist you anytime.

Piper works at a camera store. He is paid an hourly rate 16% commission on everything he sells. One week, he is paid $365 for wo

liraira [26]

P=rt+0.16s

365=20r+0.16(1500)

365=20r+240

125=20r

r=6.25

So Piper makes $6.25 an hour.

Can someone please help me with this!!!

Step-by-step explanation:

I am not fully sure what your teacher is aiming for. it friends very much on what you were just discussing in class (which I don't know).

but the first thing coming to mind is a minus sign ("-"). squaring a negative number removed the minus and makes the result equal to squaring the same positive number.

just for the undoing the 1/2 :

that is, because a fraction as exponent specifies in its denominator the root to be calculated for the basic value or expression.

so, 1/2 means square root. and yes, square is the inverse function of a square root, and it "undoes" the square root.

in exponent calculation it just means that for exponent 1 to the power of exponent 2 we simply multiply both exponents. and so, 1/2 × 2 = 1

FYI - the numerator still represents an original "to the power of" operation.

so, e.g. 3/2 would mean put the basis to the power of 3 and then do the square root of that result. or the other way around. these operations are commutative (the sequence does not matter).
