Answer:
x=11
AB=45
BC=73
Step-by-step explanation:
AB+BC=AC, so...
4x+1+7x-4=118
Combine like terms
11x-3=118
Solve for x
11x=118+3
11x=121
x=11
Now put x in each equation
AB=4x+1=4(11)+1=44+1=45
BC=7x-4+7(11)-4=77-4=73
AC=45+73=118 (which was given!)
Answer:
clockwise
Step-by-step explanation:
Conventionally, positive angles in the Cartesian coordinate plane are measured counterclockwise from the +x axis. Rotation in the negative direction is the opposite of that, so is clockwise.
Answer:
(x-4)²/16 + (y-8)²/25 = 1
Step-by-step explanation:
center (h,k): ((4+4)/2 , (3+13)/2) = (4 , 8)
a = 13-8 = 5 c = 8-5 = 3
b = √5²-3² = 4
Equation: (x-h)²/b² + (y-k)²/a² = 1
(x-4)²/16 + (y-8)²/25 = 1
