Answer:
It is not an inverse variation
We are going to form our equation in mx+b=y form.
Y= the y intercept; the distance at 0.
M= Rate of which the turtle was walking.
So, M=2 and y=7.
The equation is 2x+7=y.
Answer:
Is C
Step-by-step explanation:
For this case we have the following system of equations:
y = x + 5
y = -2x - 1
Substituting the point (-2, 3) we have:
For Line C:
y = x + 5
3 = -2 + 5
3 = 3
The line goes through this point.
For Line D:
y = -2x - 1
3 = -2 (-2) - 1
3 = 4 - 1
3 = 3
The line goes through this point.
Answer:
(-2, 3), because both lines pass through this point
Answer:
x = 2 and x = 2
Step-by-step explanation:
Simplify this problem by factoring out the coefficient 2:
y=2x^2-8x+8 => 2(x^2 - 4x + 4)
Note that x^2 - 4x + 4 is a perfect square: (x - 2)^2.
y=2x^2-8x+8 = 2(x - 2)^2
Setting this last result = to 0, we get y = 2(x - 2)^2 = 0, which has a repeated solution: x = 2 and x = 2.
