Consider that x = −5 and y = −4. which statement is true about x + y? a) the sum of x and y is a rational number. b) the sum of x and y is an imaginary number. c) the sum of x and y is an irrational number. d) the sum of x and y is neither rational nor irrational.

Option A)The sum of x and y is a rational number

Step-by-step explanation:

we know that

A rational number is a number that can be written as a ratio or quotient of two integers

so

In this problem we have

Is a rational number, because the number can be written as a ratio or quotient of two integers

Example

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
