Answer:
x = 8 and y = 5
Step-by-step explanation:
-5x + 8y = 0
-7x - 8y = -96
------------------------Add
- 12x = -96
x = 8
-5x + 8y = 0
-5(8) + 8y = 0
-40 + 8y = 0
8y = 40
y = 5
Answer
x = 8 and y = 5
The correct answer is B. -6
Answer:
(-11, -35)
Step-by-step explanation:
Everytime you reflect across the x-axis you change the y value. (x,y) → (x, -y)
Multiply both sides by 45
40=1350+a
Subtract 1350 from both sides, get answer
-1310=a
Answer:
314.2ft^2
Step-by-step explanation:
Given data
Diameter= 20ft
Radius r= 20/2= 10ft
The expression for the area is
A= πr^2
A= 3.142*10^2
A= 3.142*100
A= 314.2ft^2
Hence the area is 314.2ft^2
