Answer: 3
Step-by-step explanation:
y intercept just means plug in x = 0 to the equation and solve for y.
so
y = -4*0^2-0+3
y = 3
228 - 48 = 180
180/48 = 3.75
Its increase 375%
I divide the numerator by the denominator
6⁴ means "multiply 6 by 6 4 times"
Or
6·6·6·6
The first 3 add up to 8/12 of the garden so 4/12 are radishes and 8/12 are the others
Reduced 4/12 -> 1/3
Reduced 8/12 -> 2/3
