graph{(y-(x+3)/(x-2))(y-(2x+3)/(x-1))(x-y)=0 [-10, 10, -5, 5]}
Answer:
D) 0
Step-by-step explanation:
Remainder is zero as 10 is fully divisible by 2.
<u>Proof</u>:
- 27x^3 + 9x^2 – 3x – 10 = (3x -2) (9x^
2 +9x+5)
<u>Correct choice is</u> D) 0
Answer:
The numbers 1 to 12 must be placed in the circles of the star shown on the right. The sums of the numbers in each row, and the sum of the numbers in the six outer circles of the star, must be equal to 26. Arrange the numbers accordingly.

Y = kx
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
