Y=2 because if you subtract 52-22 you will get a difference of 30
Answer:
Y = 4
Step-by-step explanation:
<h2>
<em><u>Y </u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>3</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>9</u></em></h2><h2>
<em><u>Y </u></em><em><u>=</u></em><em><u> </u></em><em><u>4</u></em></h2><h2 />
<h2>
<em><u>that's </u></em><em><u>all</u></em></h2>
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. In this case, upon substitution, 25- 4*2*7 = -31 in which the roots are negative and iimaginary.
Answer:
(a) 180°
(b) 180°
(c) substitution property
(d) m∠3
(e) ∠3
Step-by-step explanation:
Definition: Two angles are supplementary if they add up to 180°
Proof:
By definition of supplementary angles, m∠1 + m∠2 = 180° (a) {∠1 and ∠2 are supplementary - given}
and m∠2 + m∠3 = 180° (b) {∠2 and ∠3 are supplementary - given}
Then, m∠1 + m∠2 = m∠2 + m∠3 by the substitution property (c)
Subtract m∠2 from each side. You get m∠1 = m∠3 (d)
or ∠1 ≅ ∠3 (e)
5682 divided by 4 is 1420 remainder 2 Hope that helped Have a good day! :-)
