If 1-x/x+1 is undefined then the bottom number must be 0
set
x+1=0
x=-1
Answer:
t = w/(r1 + r2)
Step-by-step explanation:
ngl, I guessed on edgenuity and it ended up being the right answer lol.
Just remember to isolate the variable and work your way through different ideas to get the right answer. There are two methods to get the right answer, but I'll use the division method (theres also the distributive property but its more work).
start--> w=t(r1+r2)
divide both sides by (r1 +r2)
answer: w/(r1 + r2) = t
Put the numbers in order from smallest to largest:
15, 19, 20, 25, 25, 28, 29, 30, 35, 37, 38, 43
Part A:
minimum = 15
maximum = 43
Q1 = (25+20) /2 = 45/2 =22.5
Q2= (28+29) /2 = 57/2 = 28.5
Q3 = (35+37)/2 = 72/2 = 36
Part B: Range = Maximum - minimum = 43-15 = 28
C: IQR = Q3 - Q1 = 36 - 22.5 = 13.5
<span>x^ − 4x − 5 = (x - 5)(x+1)
answer is </span><span>(x − 5)(x + 1) (last choice)</span><span>
