(algebra) PLZ HELP ASAP!

False

Step by step explanation:

it depends on the operation you use

For example, (-4) - (-10) = 6 (positive).

So, the set of negative numbers is not "closed" to subtraction.

(-4) + (-10) = -14

(-25) + (-2) = -27

negative numbers are a closed set under addition. You can add negative numbers all day in any way you want, and you will only get negative numbers as your result.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

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
