Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8
Hello from MrBillDoesMath!
Answer:
x^7 - 18 x^6 + 125 x^5 - 522 x^4 + 1852 x^3 - 3960 x^2 + 1728 x - 3456
See Discussion for details.
Discussion:
The polynomial is
(x-6)^3 * (x-4i)(x+4i)(x-i)(x+i) =
x^7 - 18 x^6 + 125 x^5 - 522 x^4 + 1852 x^3 - 3960 x^2 + 1728 x - 3456
Thank you,

Answer:
Because we get frightened easily.
Step-by-step explanation:
:D
1: Trapezoid
2: rectangle!
STEP BY STEP EXPLINATION
A right angle is exactly 90 degrees, so if the pentagon has 108 degree angles, it’s not a right Angle!
The parallelogram has 107 degree angles and 73 degree angles, it’s not exactly 90.
The trapezoid has two right angles! The two sides make a right angle at the vertex! So, it has a right angle!
Same thing for the rectangle!
HOPE THIS HELPS! HAVE A GREAT DAY!
