Answer:
10
Step-by-step explanation:
we call the numbers x and y
then from the given data:
x+y=18
x-y=2
we add both sides of both equations
x+y+x-y=20
2x=20
x=10
we use the first equation:
10+y=18
then y=8
the larger number is x=10
Answer:
95°
Step-by-step explanation:
Since, quadrilateral DUCK is inscribed in circle O
sum of the opposite angles of the quadrilateral is 180°
m<K +m<U= 180°
m<K= 180°- 85°= 95°

Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x
Factor the polynomial:
4u² – 20u + 25
Rewrite – 20u as – 10u – 10u, and then factor it by grouping:
= 4u² – 10u – 10u + 25
= 2u * (2u – 5) – 5 * (2u – 5)
= (2u – 5) * (2u – 5)
= (2u – 5)² <––– this is the answer.
I hope this helps. =)
