Answer:
y=8x/9
Step-by-step explanation:
Given that 8 euros were worth $9 and
24 euros were worth $27.
Let y represent the number of Euros and x no of dollars.
Given that the relation is of the form y = kx+C
When x=0 y =0,
i.e. C =0
Hence equation is of the form y = kx
Substitute x=8 and y =9
We get 9 = 8k
Or k =8/9
Hence relation is y=8x/9 is the relation between x and y.
WE can verify this for 27 dollars worth 24 euros.
24 =8/9(27) is true.
Thus equation is verified.
x = 0
f(x) = -9(3)^0
Anything to the power of 0 is 1,
f(x) = -9(1)
f(x) = -9
The answer is -9

Answer: It is a composite number since it has more factors than just itself and 1.
Step-by-step explanation:
1x20=20
2x10=20
4x5=20
We can say that the area of the figure equals...
5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle
5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²
2 by 2 triangle = 1/2 x 2 x 2 = 2 un²
2 by 5 triangle = 1/2 x 2 x 5 = 5 un²
9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²
area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²
answer: 26.75 un²
