Answer:
-1 and 10
Step-by-step explanation:
x2-9x-10
=x2-10x+x-10=0
=x(x-10)+1(x-10)
=(x+1)(x-10)
=x=-1,10
Answer:
9.433981
Step-by-step explanation:
d=(−2−6)2+(−6−(−1))2−−−−−−−−−−−−−−−−−−−−−√
d=(−8)2+(−5)2−−−−−−−−−−−−√
d=64+25−−−−−−√
d=8–√9
d=9.433981
Answer: $58.33 (Rounded bc it ends up in becoming a decimal)
Explanation: Let's make an equation for this problem. We know that if she works 3 hours for $25, 3*2=6 with 1 hour leftover. We can substitute those 6 hours for 2 sets of the 3 hours, giving us $50 so far. For the last hour, we have to divide 25 by 3 because it's only 1 hour instead of 3, meaning she'll get paid a third of the original pay rate. 25/3 equals 8.33333333334, so we'll just round that to 8.33, since it's cash. 50+8.33=$58.33. So, you'd earn 58 dollars and 33 cents for working for 7 hours.
