I believe the answer would be "infinitely many solutions" because you can put any number as x and y would be a different answer each time for both of the equations given. i hope this helps :)
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
Answer:
x = -1/8
Step-by-step explanation:
to determine the value of x in the expression-6=3/4x
first, cross multiply inorder to have a straight line equation ,then combine the like terms together and evaluate.
solution
-6=3/4x
using cross multiplication techique
4x × -6 = 3
-24x = 3
divide both sides by the coefficient of x which is -24
-24x/-24 = 3 /-24
x = -1/8
I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be B
