The statement ∀x∃y(x² = y) is true for all real numbers, as for each real number x, there exists a real number y such that x² = y.
The statement ∀x∃y(x² = y) is true as explained below:
For every real number x, there exists a real number y such that x² = y.
For example:
If x = 2, then y = 4 because 2² = 4.
If x = -3, then y = 9 because (-3)² = 9.
Since you can always find a real number y that satisfies the equation x² = y for any real number x, the statement is true for all real numbers in its domain.

The statement is true. If x and y are both real numbers, the statement is:
"for every x, there exist y such that "
This is true, because you can pick any real number, square it, and obtain another real number, y. The relation is not surjective, i.e. we will not use all possible values for y, but it doesn't matter. The statement is only asking to find a value for x^2, which we can always do.
Answer:
C. No e = h + 2
Step-by-step explanation:
The answer is (No. e = h + 2) because first of all 4 times 2/3 is 6 but 8 multiplied by 2/3 is not 10, So, A is wrong.
B is also wrong because it is basically the same thing as A.
D is not right because 6 - 2 is not 8.
So, the answer is C. No e = h + 2.
Hope this helps! :)
Answer:
15
Step-by-step explanation:
Here, 15 is not a square number so, 240 should be multiplied by 15 to make 240 as perfect square.
240* 15 = 3600
Answer:
y= -5x-13
Step-by-step explanation:
start with the linear equation
y= mx+b
indentify what you already have.
x= -4 and y= 7 and m(slope)= -5
We are solving for b, so plug in what you have.
7= -5(-4)+b
Simplify.
7= 20+b
Subtract 20 on both sides.
-13= b
Rewrite your equation with the x and y values.
y= -5x-13
Answer: f(3)=10
Step-by-step explanation:
In order to calculate f(3) you need to substitute 3 for x in function
f(x)=3x +1 :
f(3)=( 3x3) + 1
f(3)= 9+1
f(3)=10
