Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = = = 0.5, hence
y = 0.5x ← equation of variation
Answer:
I don't see the problem, Where is the image?
Answer:google
Step-by-step explanation google
- The value of x from the figure is 8
- The perimeter of AED is 30.80
To get the value of x, we will use the similarity theorem of the triangle;
a) From the given image:
On factorizing
Since x cannot be negative, then x = 8
b) The perimeter of AED = AE + ED + AD
Given
AD = 10
ED = x = 8
AE² = AD² + ED²
AE² = 10²+8²
AE² = 100 + 64
AE² = 164
AE = √164
AE = 12.80
Perimeter of AED = 12.80 + 8 + 10
Perimeter of AED = 30.80
Hence the perimeter of AED is 30.80.
