1) last number times 4 and subtract 1
2) last number times2 and add 2
3) you figure out
Coordinates of Midpoint, knowing A(x₁, y₁) and B(x₂, y₂) is
x(of midpoint) = (x₁+x₂)÷2
y(of midpoint) = (y₁+y₂)÷2
Let A(4, -2) be one end point and B(x₂, y₂) , the other end point. Moreover the coordinate of the midpoint are given= M(1/2, 0)
1) x(of midpoint) = (x₁+x₂)÷2 = (4+x₂)÷2 , but x(of midpoint) = 1/2
Then 1/2 = (4+x₂)÷2 and x₂ = -3
2) y(of midpoint) = (y₁+y₂)÷2 = (-2+y₂)÷2 , but y(of midpoint) = 0
Then 0 = (-2+y₂)÷2 and y₂ = 2
Hence the pair of the other end is B(-3,2)
Answer:
C. 314 units2
Step-by-step explanation:
Sphere Formula:
SA=4πr²
SA= 4×3.14×5²= 314 units2
Answer:
it is right dear
Step-by-step explanation:
confirm mark me as a brain list pls
#1 is true. The term they have in common is y with an invisible coefficient in-front of the second y term
#2 has zero like terms. 15 has no variable, and the other terms have different variables.
#3 has two like terms, that’s 9 and 8 which add to equal 17. The answer is 3x + 17 aka D.
#4 has two like terms, the numbers with the variable ‘n’. 4n + 7n = 11n. Your answer is 11n + 12 aka D
