Answer:
13
Step-by-step explanation:
f(-2) means you want to find the y value when x=-2. Plug in x=-2 into the f(x) equation to get: [-3(-2)]-2 = 6-2 = 4.
so f(-2)=4
But the question asks for f(-2)+9. So you add 9 to f(-2) which is 9+4 = 13
Answer:
the first one is scalne the second is isoscles and the third is equailateral
Step-by-step explanation:
scalne- all sides diff lengths
isoscles- two sides same length (remeber the two s in iSoScles)
equaliteral- all sides same length
If x=3 then the f(x)=4
If x=6 then the f(x)=7
If x=7 then the f(x)=8
During the sale,
$450 x (100% - 40%)
$450 x 60% = 450 x 0.6 = $270 = answer 1
After the sale,
$270 x 1.4 = $378 = answer 2
Answer:
hi
Step-by-step explanation:
i think,
13:14=54
13k+14k=54
27k=54
k=54/27
k=2
13×2=26 and 14×2=28
to verify the correctness of the answer-26+28=56
have a nice day
hope it helps
