Answer:
68.7
Step-by-step explanation:
We need only estimate (approximate) the value of f(x) at x = 5:
f(x)=6.87(2.5)(x – 1) → f(5)=6.87(2.5)(5 – 1).
Note that 2.5(4) = 10, so now we have (exactly) f(5)=6.87(10), which, in turn, is
equal to 68.7.
Answer:
D. –20x + 48
Step-by-step explanation:
–4(5x – 12)
= (-4) (5x) - (-4)(12)
= -20x - (-48)
= -20x + 48
The answer is 1/4
because you can add the 3/8 and 1/4, which it will be 5/8.
Then add 5/8 and 1/8 then it eqaul to 6/8
then subtract 1 by 6/8
then you got 2/8 or 1/4
Step-by-step explanation:
if n=5
5-10+9(5)-3
-5+45-3
45-8=37
if n=-9
-9-10+9( -9)-3
-19-81-3=-103
