D = b^2 - 4ac = 7^2 - 4*2*6 = 49 - 48 = 1 So there are 2 roots and
the roots are real and rational
b
Answer:
18 cm = 180 mm
Explanation:
18 cm • 10 cm (in one mm) = 180 mm
$21 I believe (it's 1 am where I am so I'm not 100% sure but I think it's correct)
Well, if you take x to be 25 seconds, there are 2.4x in 1min. So, that multiplied by 60, would be 144x. Therefore, 1/4 multiplied by 144x should be the answer.
Slope-intercept form:
y = mx + b "m" is the slope
First i would isolate the "y" in the equation.
2x + y = 4 Subtract 2x on both sides
2x - 2x + y = 4 - 2x
y = 4 - 2x or y = -2x + 4
The given line's slope is -2.
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -2/3
perpendicular line's slope is 3/2
The given line's slope is -2, so the perpendicular line's slope is 1/2.
