Answer:
The provided statement
is true in the domain of real number.
Step-by-step explanation:
Consider the provided information.
Any equation or inequality with variables in it is a predicate in the domain of real numbers.
The provided statement is:

Here, we need to find the value of x for which the above statement is true.
Since the value of x can be any real number so we can select the value of x as √5
(√5)²-4=1
5-4=1
Which is true.
Thus, the provided statement
is true.
Answer:
-50 2/5.
Step-by-step explanation:
First subtract the whole numbers:
12 - 22 - 40
= -50.
Next the fractions:
1/5 - 2/5 - 1/5
= -2/5
So the answer is -50 2/5.
Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
the equation for a line is y = m x + b
using the first set of coordinates (0,2)
2 = m * 0 + b
b = 2
using the second set of coordinates (4,6)
6 = 4 m + 2
4 m = 4
m = 4 / 4
m = 1
use those numbers into the line equation
y = x +2
Answer is C
