Answer:
the answer is y=1/3x+20
Step-by-step explanation:
because he is going 3 times faster and you are adding on the 20 minutes that he is late
The correct answer is B. 72 because you can multiply 3*6*4 to represent every combination possible.
X^2 + 8x - 5 = 0
a = 1, b = 8, c = -5
x = ( - 8 + - sqrt(64 - 4*1*-5))/2
x = ( -8 + - sqrt(64+20))/2
x = ( -8 + - sqrt (84))/2
x = ( - 8 + - 2sqrt21))/2
x = -4 + - sqrt21
Using the equation 2x + y = 4, we get the following graph.
The standard equation for the circle centre can be written by using this formula: (x-h)² + (y -k)² = r²
So, the equation in this case is: (x+6)² + (y-7)² = 81
