Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Down
Vertex:
(
0
,
7
)
Focus:
(
0
,
6
)
Axis of Symmetry:
x = 0
Directrix:
y = 8
that's all I have that may help
X = 3.8
5x+1=20
Subtract 1 on both sides to get:
5x=19
Divide by 5 on both sides to get:
x=19/5
You can leave it as a fraction as 19/5, or convert to a decimal as 3.8.

Step-by-step explanation:
In the right angled triangle, a hypotenuse is the longest line of the triangle and is always the one that is opposite the right-angle of the triangle.
If your triangle is a right angled triangle, the simplest way is to use the Pythagora's Theorem to find the length of the hypotenuse. The formula for which is
a² + b² = c² where c is the unknown hypotenuse and a and b are the other two sides.
<span>Using this formula,
3</span>² + 4² = c²
9 + 16 = c²
25 = c²
√25 = √c²
5 = c which if you notice is also the lengthiest .
Yes, because no matter how many 0's are after the decimal, the number stays the same.
