PLEASE ANSWER ASAP ALG 1 UNIT 2 LINEAR EQUATIONS I WILL GIVE BRAINLIEST AND A GIFT CARD IF CORRECT THANK YOU HURRY Colin's bank account increases each month with both interest and deposits. After 1 month, he has $200 in the account. Which equation is the slope-intercept form of the line that represents his balance y each month, x, if he knows it is parallel to the graph of last year's data, y = 800/3x?
A. y = 800/3x – 2
B. y = 800/3x – 200/3
C. y = 800/3x – 300/2
D. y = 800/3x + 2

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: 270
