Answer:
1 pear = $0.45
1 mango = 1.5
Step-by-step explanation:
8 pears + 5 mangoes = $11.10 ➡ 8p + 5m = 11.10
5 pears + 4 mangoes = $8.25 ➡ 5p + 4m = 8.25
multiply first equation by -4 and second one by 5
-4 ×(8p+5m) = 11.10 ➡ -32p - 20m = 44.4
5 ×(5p+4m) = 8.25 ➡ 25p + 20m = 41.25
add both equations up
-32p - 20m + 25p + 20m = 44.4 + 41.25
-7p = 3.15 ➡ p = $0.45
use this value to find the price of mango
5×0.45 + 4×m = 8.25 ➡ 2.25 + 4m = 8.25 ➡ 4m = 6 ➡ m = $1.5
The reason why you can’t divide zero us because zero is an undefined number. Dividing is breaking something into group and you simply can't break anything if it's not there.

Answer:
f(x,y)=(3x,3y)
Step-by-step explanation:
Dilation with the centre at the origin with scale facor k,
= f(x,y)--->f(kx,ky)
When k=3,
f(x,y)---->f(3x.3y)
