Answer:
It opens to the right and the vertex is at (0, -8).
The axis of symmetry is y = -8.
Step-by-step explanation:
The vertex is halfway between the directrix and the focus.
The focus is to the right of the directrix so the curve will open towards the right. The axis of symmetry is the line y = -8.
1/4 c + 3d
c=6 d=7
1/4 (6) + 3(7)
1.5+ 3(7)
1.5+ 21
22.5
Answer: y = 1 and x = 4
Step-by-step explanation:
-8x + 10y = -22
8x - 15y = 17
-----------------------
- 5y = -5 Add the two equations to eliminate x
y = 1 Solve for y
=====
8x - 15y = 17 (y = 1) Use y=1 in either equation
8x - 15 = 17
8x = 32
x = 4 Ta da
Answer:
Lenght - Width
2 - 4
3 - 6
5 - 10
7 - 14
Step-by-step explanation:
Because we have 5 and 10, we know that width is lenght multiple by 2, and lenght is width divided by 2.
Answer:
4
Step-by-step explanation:
The lowest common denominator for 1/2 and 1/4 is also the lowest common multiple of 2 and 4. Since 4 is a multiple of 2, 4 itself is the lowest common multiple.
1/4 would remain, and 1/2 would be written as 2/4.
