Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
Answer:
A.) $0.89
Step-by-step explanation:
2(4x+3y=7.43)
-3(5x+2y=7.03)
8x+6y=14.86
-15x-6y=-21.09
add the two equations
-7x=-6.23
divide by -7
x=.89
Answer:
The point is (-5, -2).
Step-by-step explanation:
Translation to the left means subtract from x value. Translation down means subtract from y value.
(x-7)^2+y^2=225={x-7- 225-y2}
x=225-y2+7
It would be 3 Adult tickets and 6 Student Tickets
10 x 3 = 30
6 x 8 = 48
48 +30 = 78
