Answer: I can help you but can you tell me the 3rd letter on the chart. Is it -6 or -8
Step-by-step explanation:
9x - 5y = k Substitute in the x- and y-values (x = 9 and y = 8)
9 (9) - 5(8) = k Multiply
81 - 40 = k Subtract
39 = k
When k = 39, (9, 8) will be a solution to the equation.
Answer:
11?

Answer:
The area of the shaded region is 30.5 cm^2.
Step-by-step explanation:
So, first you need to find the area of the circle and rectangle separately.
The diagram shows that the circle radius is 5 cm; use the formula pi*r^2 to solve for the area.
The area of this circle:
3.14*5^2
3.14*25
=78.5 cm
The area of this rectangle:
8 cm*6 cm = 48 cm
Now subtract the rectangle's area from the area of the circle.
78.5-48 = 30.5 cm
