2: Which equation does not belong with the other three? Explain. Thank you so much in advance.
2 answers:
y = x² + 6
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 0.5x - 0.2, y = 4x + 3 and y = x +
are all in slope- intercept form and represent equations of straight lines
y = x² + 6 is not in this form and is not a straight line equation.
In fact it is the equation of a parabola

Answer:
2x -y ≥ 4
Step-by-step explanation:
The intercepts of the boundary line are given, so it is convenient to start with the equation of that line in intercept form:
... x/(x-intercept) + y/(y-intercept) = 1
... x/2 + y/(-4) = 1
Multiplying by 4 gives the equation of the line.
... 2x -y = 4
This line divides the plane into two half-planes. The half-plane that is shaded is the one for larger values of x and/or smaller values of y than the ones on the line. So, for some given y, if we increase x we will get a number from our equation above that is greater than 4. Hence, the inequality we want is ...
... 2x -y ≥ 4
We use the ≥ symbol because the line is solid, so part of the solution space.
Answer:
John is 9.21 km form the school.
Step-by-step explanation:
John leaves school to go home. His bus drives 6 kilometres north and then goes 7 kilometres west. It is required to find John's distance from the school. It is equal to the shortest path covered or its displacement. So,
So, John is 9.21 km form the school.
