C) x = -19/10 because when solving it with substitution u get x=-19/10 & y=153/10
Answer:
i think it's <C and <R since they're 90 degree angles, though they are small
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
I can't really graph it here but:
Slope: <span><span>1/4</span></span>Y-Intercept: <span>−<span>5</span></span>
