Answer:
-15/8 or -1 7/8, 1.875
Step-by-step explanation:
Answer:
14, 42
Step-by-step explanation:
Set A = {−7, −4, 2, 14, 21, 34, 42}
Set B = {even numbers}
Set C = {multiples of 7}
There is only one question asked
Which numbers in Set A are elements of both Set B and Set C,
We need it to be even and a multiple of 7
14 is even and a multiple of 7 and 42 is even and a multiple of 7
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: $768.50
Step-by-step explanation:
If $725 was the price before sales tax, $768.50 would be the total amount after the 6% sales tax increase.
***If you found my answer helpful, please give me the brainliest. :) ***
1. -18 +15x = 3(4x-6) + 3x
-18 + 15x = 12x - 18 + 3x
-18 + 3x = -18 + 3x
3x = 3x
x = All Real Numbers (because we don't know what x is since the equation is 3x = 3x, we can assume that it is all "real" numbers)
2. -10 + 5x = 5(x - 3) + 5
-10 + 5x = 5x - 15 + 5
-10 = -10
Answer Undefined (because the x coefficients canceled out, we don't know what x even is, so we can claim it as undefined.)
