Answer: 7.42x10^3 . . . . .
Answer:
-6 < x <9
Step-by-step explanation:
-7 < X -1 <8
Add 1 to all sides
-7+1 < X -1+1 <8+1
-6 < x <9
Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.
Answer:
5/3 or 1.666...
Step-by-step explanation:
SLOPE: get the difference of each coordinate and divide them.
two points: A(2,7) and B(5,12)
we subtract ax from bx:
5 - 2 = 3, "dx"
and subtract ay from by:
12 - 7 = 5, "dy"
now we divide dy/dx:
5/3 or 1.666...
that's the slope
Answer: 90 degrees
Step-by-step explanation: A circle is 360 degrees so since that is 1/4 you can divide
360/4 = 90 (: hope this helps
