Answer:
Yes, the expressions are equivalent.
Step-by-step explanation:
Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.
and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.
Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2
Answer:
3 1/2 hours
Step-by-step explanation:
84/24 = 3.5
N = 1 corresponds to day 1
n = 2 corresponds to day 2
...etc etc...
n = 21 corresponds to day 21
Plug in n = 21
a_n = 100 + (n-1)*4
a_21 = 100+(21-1)*4 ... replace every n with 21
a_21 = 100 + 20*4
a_21 = 100+80
a_21 = 180
Answer: C) 180 yards
Answer:
-4
Step-by-step explanation:
The formula for slope is: m=y2-y1/x2-x2
12-(-20)/5-13
Answer: B
Step-by-step explanation:
Slope = rise/run (aka change in y/change in x)
Slope = (-9-(-9.75))/(-4-(-1)) = 0.75/-3 = -1/4
