Answer:
3) 156°
4) 24°
5) 24°
6) 24°
Step-by-step explanation:
m∡2: 180 - 156 = 24°
m∡3: 156° (is vertical to angle labeled as 156°)
m∡4: 24° (is vertical to angle 2)
m∡5: 156°
m∡6: 24° (alternate-interior to angle 4)
m∡7: 156° (corresponding angle with ∡3)
m∡8: 24° (vertical with angle 6)
Answer:
(-6, 0)
Step-by-step explanation:
Check out A): (-6,0). This satisfies 2y-2x=12: 2(0) - 2(-6) = 12, and also satisfies x^2+y^2=36: (-6)^2 + 0^2 = 36. (-6, 0) is therefore a solution of the given system.
185 plus the second number which is 196 plus 90 is 471
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)
Answer:
2/3
Step-by-step explanation:
All you need to do is find the ratio of two corresponding sides (smaller figure to larger figure)
16/24 = 2/3
