The is a great question! You could try to estimate or just calculate it but it's 21
Start by writing out the system of equations.
The easiest way to solve this system of equations is the elimination method. This is because both equations contain opposites of each other that you can cancel out.
Add the system of equations together. After adding, everything cancels out. 4x + (-4x) = 0 ; -y + y = 0 ; 3 + (-3) = 0.
You are left with the equation of 0 = 0. Since this is a TRUE statement, this means that there are infinitely many solutions to this system of equations.
If you were left with a false statement, for example 4 = 0, then the answer would be "no solution".
Another way to solve this system of equations is by the substitution method. This method works best if you are given a system of equations with one variable clearly defined.
For example, the system of equations could be:
y is equal to 3x + 4, so you could easily substitute y into the first equation. The elimination method wouldn't be the best choice because the system of equations are in the standard form Ax + By = C.
Generally any system of equations in the standard form are easier to solve using the elimination method. Hope this helped, good luck!
Answer:
no
Step-by-step explanation:
The set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The question is incomplete.
The complete question is:
Set of integers x such that x - 5 is less than 25.
We have an inequality:
x - 5 < 25
Adding 5 both sides:
x - 5 + 5 < 25 + 5
x < 30
x ∈ (-∞, 30) where x is an integer.
Thus, the set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

The distance formula is:
We are given two points in the form (x,y), so plug in the values to the distance formula:
Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:
The square and square root cancel each other out leaving us with 25.
The answer is 25.
