Answer:
See below
Step-by-step explanation:
To write informal negations, change the existential quantifiers "some, there exists" for universal quantifiers "All, for every" and viceversa. Then write the informal negation of the statement after the quantifiers:
1) Some suspicions were unsubstantiated.
2) Some suspicions were substantiated.
3) All suspicions were substantiated.
4) No suspicions were unsubstantiated. Equivalently, Every suspicion was substantiated.
5) No suspicions were substantiated. Equivalently, Every suspicion was unsubstantiated.
A. 0.98=.980 is true because the zero doesn't change the value, it is simply a place holder. If you add a 0 to 0.98, it becomes 0.980, so it is the same number.
For this case when defining variables we have:
x: number of beehives
y: amount of honey produced
We write the function that models the problem:
For 6 beehives we have:
Answer:
Newton gets 240 pounds of honey from his bees every year
Answer:
72 = 2 * 2 * 2 * 3 * 3
Step-by-step explanation:
Answer:
rearrange them properly to get
x-y=7
-3x+y=12
( by elimination method)
x-y = 7
-3x+y=
(x+ –3x) + (–y+y) = (7+12)
-2x+0= 19
x= -9.5
from eqn(i)
x-y=7
-9.5 - y=7
-y=16.5
y= -16.5
