Answer:

C.) Square both sides twice and then solve the resulting linear equation.

Step-by-step explanation:

We are given a equation:

$\sqrt{3x+4}=\sqrt{3x}+4$

On squaring both sides, we get

$3x+4=3x+16+8\sqrt{3x}$

= $8\sqrt{3x}=-12$

again on squaring, we get

$64\times 3x=144$

⇒ x=3\4

Hence, solving this equation required Squaring both sides twice and then solving the linear equation

Hence, Correct option is:

C.) Square both sides twice and then solve the resulting linear equation.

Need some help with these last few problems Thank you for your time and help

(1) On the unit circle, you have $\sin x=-1$ when $x=-\dfrac\pi2$ , and more generally this is the case whenever you perform a full rotation about the origin. This means $\sin x=-1$ any time $x=-\dfrac\pi2+2n\pi$ where $n$ is any integer.

(2) When $x=-90^\circ$ , you have $y=f(-90^\circ)=\cos(-90^\circ)=0$ .

(3) When $x=-45^\circ$ , you have $y=f(-45^\circ)=\tan(-45^\circ)=-1$ .

(4) The law of sines says that

$\dfrac{12}{\sin40^\circ}=\dfrac{e}{\sin55^\circ}\implies e\approx15.292$

(5) The law of cosines says that

$b^2=6.5^2+8^2-2\times6.5\times8\cos37^\circ\implies b\approx4.816$

Lara employed a residential cleaning service to tidy up her home. They charged her $150 for 3

Natalka [10]

Answer:

Step-by-step explanation:

Find the rate that was charged for Lara's time

rate = dollars / hour

The use this rate to calculate how many hours it took to clean Roy's house, since the rates are the same. Solve for hours.....

rate for Lara = dollars / hour = $150 / 3 hour = $50 / hour

rate for Roy = dollars / hour Solve for hours

multiply both sides by hours

(rate for Roy) (hour) = (dollars / hour) (hour)

(rate for Roy) (hour) = (hour) (dollars / hour) right side hours cancel

(rate for Roy) (hour) = (dollars) divide both sides by (rate for Roy)

(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

now the rate for Roy on the leftside cancel

(rate for Roy) (hour) / (rate for Roy) = (dollars) / (rate for Roy)

(hour) = (dollars) / (rate for Roy) Plug in $225 charged to Roy

and the $50 / hour rate

hour = $225 / ($50/hour) ( 1 over 1 / hour ) = hour

= $(225/50) hour think about 1 / (1/2) = 2 the same with units

hour = 4.5 hours
