Answer:
Step-by-step explanation:
The line is passing through 2 points: (0,9 and (3,3)
slope=(9-3)/(0-3)=-2
equation is : y-9=-2(x-0) or y=-2x+9
The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line
x = 2
Answer:
y=-9
Step-by-step explanation:
-3(y+2)=21
1st Open parenthesis
-3y-6=21
+6 +6
-3y=27
/-3 /-3
y=-9
given the following sets.
A = {0, 1, 2, 3}
B = {a, b, c, d}
C = {0, a, 2, b}
Find B C.
Answer:
x = - 9
Step-by-step explanation:
Given
= - 3 ( multiply both sides by 3 to clear the fraction )
x = - 9
