Y=2x + 4<br> y = 2(x + 2)<br> what is x
Oxana [17]

Answer:

I believe 1.) is x=y-4/2 and 2.) x=y-4/2 as well

Step-by-step explanation:

1.)

y=2x+4

-subtract 4 on both sides-

y-4=2x

-divide 2 on both sides-

x=y-4/2

2.)

y=2(x+2)

-distribute the 2-

y=2x+2

-subtract 2 on both sides-

y-2=2x

-divide 2 on both sides-

x=y-2/4

I dont know exactly if this is correct, but i hope it helps! :)

a man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is 64 degrees. He the
mamaluj [8]
So hmm notice the picture below

thus  \bf \cfrac{y}{tan(64^o)}=\cfrac{y}{tan(46^o)}-100\implies &#10;\cfrac{y}{tan(64^o)}-\cfrac{y}{tan(46^o)}=-100&#10;\\\\\\&#10;y\left[ \cfrac{1}{tan(64^o)}-\cfrac{1}{tan(46^o)} \right]=-100\implies y=\cfrac{-100}{\frac{1}{tan(64^o)}-\frac{1}{tan(46^o)}}

make sure your calculator is in Degree mode, since the angles are in degrees

A local club is arranging a charter flight. The cost of the trip is $360 each for 90 passengers, with a refund of $2 per passeng
ludmilkaskok [199]
A. R(x)=(360-2x)(90+x)\\R(x)=32400+360x-180x-2x^2\\R(x)=-2x^2+180x+32400

B. R(x)=-2x^2+180x+32400\\R'(x)=-4x+180=0\\180=4x\\45=x\\\\R(45)=-2(45)^2+180(45)+32400\\R(45)=-2(2025)+8100+32400\\R(45)=-4050+40500\\R(45)=36450\\\\90+45\\135

135 passengers will maximize the revenue at $36,450.
