Line FE because the radius is from one point of the circumference of the circle to the center of the circle and that is the only option
Answer:
She is incorrect. The correct answer is 285.74
Step-by-step explanation:
A= (pi)r^2
Training wheel: A= (3.14)(3)^2=28.26in^2
Wheel: A= (3.14)(10)^2= 314in^2
314-28.26=285.74in^2
Answer:
y =-2x+7
Step-by-step explanation:
Hello : let A(2,3) B(1,5)
the slope is : (YB - YA)/(XB -XA)
(5-3)/(1-2) = 2/-1 =-2
an equation is : y=ax+b a is a slope
y = -2x +b
the line through point (2,3) : 3 = (-2)(2)+b
b = 7
the equation is : y =-2x+7
7v3 is the radical simplified... to do this you can use multiple methods. I like to use a factor tree.
Here’s a link to a website that explains some different methods of solving:

Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y
Set up a system of equations and use substitution
x + y = 2.75
x + 7y = 11.75
x + y = 2.75 can be rewritten as y = -x + 2.75
x + 7 (-x + 2.75) = 11.25
-6x + 19.25 = 11.25
-6x = -8
x = .75
plug x back into other equation to find y
y = -.75 + 2.75
y = 2.00
1 hot dog = $0.75
1 hamburger = $2.00
