Answer:
Angle BCD = 73 + 53 = 126 degrees
Step-by-step explanation:
-3(r-9s=2)+(3r-3s=-10)
24s=-16
s=-2/3, now using either original equation we can solve for r.
3r-3s=-10 becomes:
3r+2=-10
3r=-12
r=-4 so the solution is the point:
(s,r)=(-2/3, -4)
Answer:
no
no
yes
Step-by-step explanation:
the first two tables have inputs which solve for more than one output which means they are not functions
Answer:
Step-by-step explanation:
Please write points using parentheses: (4, 5) and (-4, 8}.
(4, 5) is in the 1st quadrant and (-4, 8} is in the 2nd. Reversing the order of these two points yields (-4, 8) and (4, 5). From this we can see that while moving from (-4, 8) to (4, 5) involves following a line with negative slope (because the y-coordinate decreases from 8 to 5 as the x-coordinate increases from -4 to +4). This sloping line is the hypotenuse of a right triangle. Draw a vertical line segment through (-4, 8) and a horizontal line segment through (4, 5). This hypotenuse, the vertical line segment and the horizontal line segment are the boundaries of the desired right triangle.
