Answer:
d 40 times 23=920
Step-by-step explanation:
if you did 60 times 15= 900
the highest is 920
Answer:
-3
Step-by-step explanation:
means
What is the -coordinate value that corresponds to . That value is -1.
What is the -coordinate value that corresponds to . That value is 0.
So this implies .
Substitute this into the parabolic equation,
We're told the line intersects twice, which means the quadratic above has two distinct real solutions. Its discriminant must then be positive, so we know
We can tell from the quadratic equation that has its vertex at the point (3, 6). Also, note that
and
so the furthest to the right that extends is the point (5, 2). The line passes through this point for . For any value of , the line passes through either only once, or not at all.
So ; in set notation,
B. All rectangles are parallelograms. <span />
