f(x) = y = x+3, Consider y=x+3. You just switch x and y:
so y= x+3, becomes x=y+3. Once done, you isolate y:
x=y+3 or y = x-3. This this the inverse function of f(x)
Answer:
The area of the whole field is 54400yd^2
Step-by-step explanation:
says that I add 10 yards in each zone, that means that 10 yards is added twice at 1000 yards
1000yd + 2*10yd = 1020yd
we have to know that one yard equals 3 feet
so to have the length in feet we only multiply it by 3
1020 * 3 = 3060ft
Now that we know the length and width of the court, we can calculate the area by multiplying them
a = b * h
a = 3060ft * 160ft
a = 489600 ft^2
the result is in square feet
if we want it in square yards we just have to divide 2 times by 3
489600/(3*3) = 54400yd^2

Answer:
6
Step-by-step explanation:
We want to expand this; (x + y)⁴
This can be written as;
(x + y)² × (x + y)²
This gives;
(x² + 2xy + y²) × (x² + 2xy + y²)
This gives;
x²(x² + 2xy + y²) + 2xy(x² + 2xy + y²) + y²(x² + 2xy + y²) = x⁴ + 2x³y + x²y² + 2x³y + 4x²y² + 2xy³ + x²y² + 2xy³ + y⁴
Simplifying gives;
x⁴ + 4x³y + 4xy³ + 6x²y² + y⁴
Thus, the coefficient of x²y² is 6
