-2+1/2 (6) I'd 1 so A is correct
Answer:
-4
Step-by-step explanation:
f(-1) = 2(-1) - 2 = -4
60/2 equals 30 then 30x4 is 120. Is parents give him a 120$
1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or
8:32.
2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x =
52 [tex] \frac{miles}{hour} [tex]
3) Which typing time is fastest? I answered this earlier, refer to it please refer to it:

First do any exponents: 3 to the 0 power would equal 1. Then multiply and divide in order: 2x1=2, 2/2=1. Then subtract: 23.6-1=22.6 :)
