Answer:
32
Step-by-step explanation:
80/2 = 40
64/2 = 32
so she can make about 32
Answer:
The diameter of the circle is 13.
Answer:
(-2.2, -1.6), (3, 1)
Step-by-step explanation:
You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.
Use the first equation to write an expression for x, then substitute that into the second equation:
x = 2y +1
y^2 -3(2y+1)(y) +8 = 0
-5y^2 -3y +8 = 0
-(5y +8)(y -1) = 0
y = -8/5 or y = 1
The corresponding values of x are ...
x = 2(-8/5)+1 = -11/5
x = 2(1) +1 = 3
The solutions are (x, y) = (-2.2, -1.6) and (3, 1).
2√2
= 2√2
B)
√3(√2+380√2-80)
= -80√3+381√6
I hope that's help and sorry for the late answer !
Answer:
it is the first one
y=\sqrt{2x-6-1}
