If you have paid back 150 a month you multiply by 10 then you subtract $6900, your remaining balance is $5,400. Good luck with your equation.
Answer:
The Option is D) ΔDEC ≅ ΔDEA
ΔDEC ≅ ΔDEA ….{By Side-Angle-Side Congruence Statement}
Step-by-step explanation:
Given:
AE ≅ EC
∠AED ≅ ∠CED = 90°
To Prove:
ΔDEC ≅ ΔDEA
Proof:
In ΔDEC and ΔDEA
AE ≅ EC ……….{Given}
∠AED ≅ ∠CED …………..{measure of each angle is 90°}
ED ≅ ED ……….{Reflexive Property}
ΔDEC ≅ ΔDEA ….{By Side-Angle-Side Congruence Statement}
The answer is the second choice:
a, if a is greater than or equal to 0 and
-a, if a is less than or equal to 0
You can check this by testing out values.
The absolute value of 5 is 5 while the absolute value of -5 is -(-5) or 5. This follows the chosen function.
If 2 + 3i is a zero, then 2 - 3i is also a zero
x(x - 2 - 3i)(x - 2 + 3i)
= x(x² - 2x + 3ix - 2x + 4 - 6i - 3ix + 6i - 9i²
= x(x² - 4x + 4 + 9)
= x(x² - 4x + 13)
= x³ - 4x² + 13x
