5(-2a-8) < -9a + 4
Use distributive property on left side:
-10a -40 < -9a + 4
Add 40 to both sides
-10a < -9a + 44
Add 9a to both sides
-a < 44
Multiply both sides by -1 and reverse the inequality sign:
A > -44
Answer: a > -44
A theorem called "inscribed angle theorem," states that angle θ is half of that of angle 2θ that subtends an identical arc on the circle.
So, ∠ABC = center angle * 1/2
The center angle is 192°, so substitute with that number and solve.
∠ABC = 192 * 1/2
∠ABC = 96°
Therefore, the answer is 96°
Best of Luck!
Answer:
Step-by-step explanation:
(-3x + 2)(45x + 21) + (-4x + 25) = 50
-135x^2 - 63x + 90x + 42 - 4x + 25 = 50
-135x^2 + 23x + 67 = 50
-135x^2 + 23x + 67 - 50 = 0
-135x^2 + 23x + 17 = 0
quadratic formula : x = (-b ± √b^2 - 4ac)/2a
a = -135, b = 23, c = 17
x = -23 ± √23^2 - 4(-135)(17) / (2(-135)
x = (-23 ±√9709 )/ -270
x = 23/270 ± 1 / 270√9709/270
x = 0.4501 or x = - 0.2798 <=== these answers are rounded
No one wants to date you or anyone else because this is a Q&A app for homework, Quizs, and Classwork.
Plug in e for 3.
10(3+7)
Use the distributive property. a(b+c)= ab+ac
10*3= 30, 10*7=70
30+70=100
The expression equals 100.
I hope this helps!
