Hello,
Here is an analytic method.
Equation of the circle of center C(13,-31) and radius 37:
(x-13)²+(y+31)²=37²
x=25
We are going to calculate y
(25-13)²+(y+31)²=1369
==>(y+31)²=35²
==>(y=4 or y=-66)
So b=4 or b=-66
Answer:
(-1,2) is domain
Step-by-step explanation:
Answer:
A. f(x) = x²
Step-by-step explanation:
Observing the values
when x= -2..............f(x)= 4..................this is x²............-2²= 4
when x= -1..............f(x)= 1......................this is x²............ -1² = 1
when x= 0..............f(x)=0.....................this is x².......... 0²= 0
when x= 1.............f(x)= 1........................this is x²........ 1²= 1
When x=2........... f(x) = 2...................... this is x²........ 2² = 4
⇒The first option is correct.
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7
i hope this helps, and i'm sorry if it's wrong!! :)
The equation given in the question is definitely solvable for finding the value of the unknown variable "x". There is only one unknown variable and one equation.The equation given in the question is
10/8 = (x - 10)/10
(10 * 10)/8 = (x - 10)
100 = 8(x - 10)
100 = 8x - 80
Reversing the two sides, we can write the equation as
8x = 100 + 80
8x = 180
x = 180/8
= 22.5
So the value of the unknown variable comes out to be equal to 22.5. I hope the procedure is clear enough for you to understand.
