First, subtract 2/3 from both sides and you get
Then multiply both sides by 6/5 and you get
Found this when I was doing my own work, hope this helps.
Answer:
D)
Step-by-step explanation:
<u>Vertex Form of a Vertical Parabola:</u>
Vertex ->
Axis of Symmetry ->
Vertical Scale Factor ->
- To turn into vertex form, we need to complete the square on the right side
- Therefore, if , then completes the square on the right side
- This becomes
- This means that our function in vertex form is
Therefore, the vertex of the graph is .
Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m
