Help pls due today ty

Step-by-step explanation:

Function A

b= 2.5

5= 1.5m+ 2.5

1.5m= 2.5

m= 1.667

m= 5/3

y= 1.667 x+2.5

Blank 1 : 1.667 or (5/3)

Blank 2: -4.5

rate of change can be positive or negative

Blank 3: Function B

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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
