Y is obtained form x by multiplying x by -1/3.
so when x = -3 y = -3 * -1/3 = 3/3 = 1
when y = 0, 0 = x * -1/3 so x = 0
so b) is the correct choice.
Answer:
D: 19 should have been subtracted from, not added to, both sides of the equation.
Step-by-step explanation:
Because if we subtract 19 from both sides, we directly get the value of x.
Equation:-
x + 19 = 34
Subtracting 19 from both sides,
=> x + 19 - 19 = 34 - 19
=> x = 15
I got this, i hope it help
Answer:a
Step-by-step explanation: have a nice day
If we have the directrix at x = -3 (a vertical line) and the focus at (3, 0), then the vertex of the parabola is between these two, at the origin (0, 0). The parabola itself opens in the direction of the focus, which is to the right. The general equation for a parabola opening to the right is x^2 = 4cy, where c is the distance from the vertex to the focus (or to the directrix). In this case, c = 3 (from (0,0) to (3,0)). Therefore, the equation is x^2 = 12y, which is identical to y = (1/12)x^2, choice A.
