The equation for a parabola can also be written in the "vertex form":
x = a (y - h) ^ 2 + k
In this equation, the vertex of the parabola is the point (h, k).
We have then:
x = y2 + 6y + 1
We look for the vertice:
0 = 2y + 6
y = -6 / 2
y = -3
Substituting:
x = (-3) ^ 2 + 6 (-3) +1
x = -8
Substituting the vertice point:
x = (y + 3) ^ 2 - 8
Answer:
x = (y + 3) ^ 2 - 8
option C

The way you would answer this question is dividing 27 by 3, which equals 9, (this because its the converse of doing the question "Lucia spotted 9 fish, but her sister Betina spotted 3 times as many (3x9=27)

jalen jogged 10 miles due north, then turned due west and jogged 5 more miles. How msny miles is jalen from his starting point?

Juliette [100K]

Answer:

Jalen is <u>11.18 miles</u> from his starting point.

Step-by-step explanation:

Given:

Jalen jogged 10 miles due north, then turned due west and jogged 5 more miles.

Now, to find miles Jalen jogged from his starting point.

So, below is the figure attached to describe the scene.

Now, to get the distance of Jalen jogged from his starting point we use pythagoras theorem:

$AB^2+BC^2=AC^2\\\\10^2+5^2=AC^2\\\\100+25=AC^2\\\\125=AC^2$

<em>Using square root on both sides we get:</em>

$11.18=AC\\\\AC=11.18\ miles.$

Therefore, Jalen is 11.18 miles from his starting point.

The sum of three numbers is 124. The third number is 3 times the first. The second number is 9 more than the first. What are the

Leona [35]

Answer:

23, 32, 69

Step-by-step explanation:

3 numbers x, y, z

z = 3x

y = x + 9

x+y+z=124

x + (x + 9) + 3x = 124

5x + 9 = 124

5x = 115

x = 23

y = 32

z = 69

check: 23 + 32 + 69 = 124
