Answer:
a) Q(-2,1) is false
b) Q(-5,2) is false
c)Q(3,8) is true
d)Q(9,10) is true
Step-by-step explanation:
Given data is is predicate that then . where are rational numbers.
a)
when
Here that is satisfied. Then
this is wrong. since
That is Thus is false.
b)
Assume .
That is
Here that is this condition is satisfied.
Then
this is not true. since .
This is similar to the truth value of part (a).
Since in both satisfied and for both the points.
c)
if that is and
Here this satisfies the condition .
Then
This also satisfies the condition .
Hence exists and it is true.
d)
Assume
Here satisfies the condition
Then
satisfies the condition .
Thus, point exists and it is true. This satisfies the same values as in part (c)
Answer:
-9/4, -0.75, -6/10, 5/3, 2.1
Step-by-step explanation:
This is a lot easier to figure out if you simplify the fractions and then change them to decimals
So -9/4 = -2 1/4 or -2.25
-0.75
-6/10 = -0.60
5/3 = 1 2/3 or 1.67
2.1
When you are ordering negatives, the biggest negative is the least. That is why -9/4 (-2.25) is the least number out of the five given.
The next one would be -0.75, because it is the second biggest negative fraction.
The next one is -0.60 because that is the 3rd biggest negative fraction (or the smallest because this is the last negative)
Now, because we're in the positives we start with 1.67, because it is smaller than the other number.
2.1 is our last number, so it is the greatest!

(b - 4z)/7 = a
b - 4z = 7a
b = 7a + 4z
Answer: b = 7a + 4z
