A triangle was dilated by a scale factor of 4. If tan a° = four thirds and segment FD measures 12 units, how long is segment EF? triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees segment EF = 6 units segment EF = 9 units segment EF = 12 units segment EF = 16 units

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

y=foot

x=foram

a. easy, plug 17 for x and evaluage for y

y=0.860(17)+3.302

y=14.62+3.302

y=17.922 inches

b. rate of change is slope

y=mx+b

m=slope

so

rate or change is 0.860 inches per legnth of forarm

c. what data

d. it is a function

since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line

it is a function
