Answer:
it should be YZ = 35
Step-by-step explanation:
x = 1.4 (or 21/15)
12x - 15 = 6 - 3x
+3x +3x
-----------------------
15x - 15 = 6
+15 +15
15x = 21
/15 /15
----------------------
x = 21/15 or
x = 1.4
Melissa = D
Victor = C
d(x) = { (x,y): y = sqrt(x) and y >=0 }
since sqrt function requires x to be >=0 so
<u>x >= 0</u>
or abot 0.6
