Answer:
parallel line: y=-3x+14
perpendicular line: y=1/3x +2/3
Step-by-step explanation:
For the parallel line, use the point-slope formula to find the equation of the parallel line (since the slope is the same as the given line and the point (4,2) is given. For the perpendicular line, use the opposite reciprocal of the slope of the given line and use the point-slope formula again. The point-slope formula is Y-Y1=m(X-X1)
Answer:
234,100
anything that is below 50 will go down.
Step-by-step explanation:
Answer:
29. (5,0) and (-7/2,0)
30. (-1,0) and (5/7,0)
Step-by-step explanation:
29. y=2x² - 3x - 35
y = (x-5)(2x+7)
y is 0 at x = 5 and -(7/2)
31: y=-7x² - 2x + 5
y = -(x+1)(7x-5)
y is 0 at -1 and 5/7
See the attached graph.
Answer:
The shape is a square and a triangle, so all sides of the square are equal to 6, and applying the Pythagorean law to a right-angled triangle, we can find the value of x
