Step-by-step explanation:
An inequality where the difference between 2 and a number is at least negative 1 will be x - 2 ≥ -1.
<h3>What is the inequality?</h3>
The first part of the inequality is that there is a difference between a number and 2.
Assuming that number is 2, the first part is:
x - 2
The result of this subtraction at least negative 1. When a number is at least a number, it means that it is either that number or larger.
So the total inequality is:
x - 2 ≥ -1

An equivalent expression would be s+15
You simplify the expression.
So yea the answer is s+15
Answer:
Step-by-step explanation:
From the upper isosceles triangle,
The answer is: x=±√5y [Note: If and only if at the lower triangle is NOT isosceles]
Exterior angle to the isosceles triangle = 2(2x^2 – 2x) [because the exterior angle of a triangle is equal to the sum of two opposite interior angles]
Therefore, the exterior angle = 4x^2 – 4x
Also,
The exterior angle is equal to the sum of the two interior base angles of the lower triangle
Thus, 4x^2 – 4x=(3x^2+4x) + (5y – 8x)
By collecting like terms,
4x^2 – 3x^2 – 4x – 4x + 8x – 5y = 0
x^2 – 5y = 0
x^2 = 5y
By taking the square root of both sides
x=±√5y
