Answer:
substitution it would make the most sense in this case and be the fastest way . by fastest i mean the least amount of steps
Step-by-step explanation:
Answer: x=3
I got to the answer by doing simple math. Both sides must be even.
5x-4
5(3)-4= 15-4 = 11
x+8
3+8= 11
So x=3
Answer:
Step-by-step explanation:
Answer:
y = (x - 10)^2 / 100 + 1
Step-by-step explanation:
given:
A suspension footbridge has two 2-meter vertical supports 20 meters apart so the cable connecting 'em will be a convex parabola
The lowest point of the cable, which is the vertex, 1 meter above the path.
y-axis represents the left support and the other vertical support is at x=20
by symmetry, the vertex is mid-pt between the two supports, @ x=20/2=10
so vertex is at (10,1)
vertex form of parabola is y = a(x - h)^2 + k, where (h, k) is the vertex
so y = a(x-10)^2 + 1
at y-axis, x=0, y=2
2 = a(0-10)^2 + 1
2 - 1 = 100a
a = 1/100
so the eqn is y = (x - 10)^2 / 100 + 1
