Answer:
-0.8 - 0.5b - 1.4c
Step-by-step explanation:
Take the b and the c away
Then times the 0.2 by all the numbers but don't add them
Once your done you and the b and c back to you equation
Answer:
C
Step-by-step explanation:
let y = f(x) and rearrange making x the subject
y = ( cube both sides )
y³ = x + 12 ( subtract 12 from both sides )
y³ - 12 = x
change y back into terms of x with x = (x) , then
(x) = x³ - 12
Answer:
3r + t
Step-by-step explanation:
it is that because you multiply one to t and r, and the are left with 2r + r + t. You add 2r to r and get 3r, with a left over of t.
Here we go!
The quadratic formula: x = [-b ± √(b2<span> - 4ac)]/2a
a = 1 (understood coefficient)
b = 12
c = -13

Okay, so here, we split into 2 problems. If 14 were positive:
If 14 were negative:
So,
