Answer:
-0.125
Step-by-step explanation:
Original coordinates of the points:
A (8,15) ; B (12,13) ; C (8,10)
Dilated scale factor of 3.
A ⇒ 3x = 3(8) = 24 ; 3y = 3(15) = 45 ⇒ A' (24,45)
B ⇒ 3x = 3(12) = 36 ; 3y = 3(13) = 39 ⇒ B' (36, 39)
C ⇒ 3x = 3(8) = 24 ; 3y = 3(10) = 30 ⇒ C' (24, 30)
The given image forms a right triangle. So, I'll get the short leg and long leg of the right triangle to solve for the hypotenuse, length of CB.
Short leg: y value of B and C
39 - 30 = 9
Long leg: x value of B and C
36 - 24 = 12
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
15 = c
The length of CB is 15 units.
The first two are 6 and 28. The factors of 6 add up to the same thing as 6.
Six
1 * 2 * 3 = 6
1 + 2 + 3 = 6
Twenty eight
1 + 2 + 4 + 7 + 14 = 28 (the multiplication is not the same as for 6).
Four hundred ninety Six
This one is kind of hard to believe
It is 16 * 31
1 + 2 + 4 + 8 + 16 + 248 + 124 + 62 + 31 = 496

Answer:
18
Step-by-step explanation:
y=k×x
15=k×5
=>k=15/5=3
when x=6,
y=3×6
=18
