Answer:
Step-by-step explanation:
It is a function. Every x has only 1 y associated with it. You cannot find an exception to this rule.
Stated another more common way: if you take a ruler and lay it flat on the graph so that the ruler is parallel to the y axis, you will find the ruler will go through only one y for every x. That's called the vertical line test.
Answer:
112 in^2
Step-by-step explanation:
The equation to calculate the area of a circle is A=πr^2. We can solve for the radius of the circle by:
1) plugging in our known value, A=7. So 7=πr^2
2) dividing both sides by π.
7/π=r^2
3) square rooting both sides.
Sqrt(7/π)=r
Plug that into a calculator and you get about 1.4927
Now we multiply that by 4, giving us our new radius of about 5.9708
Plugging that number back into the equation A=πr^2 as r will give us 112.
Answer:
Its factorisation method friend. May it helps u.
Answer:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
