Answer:
5
Step-by-step explanation:
The Y intercept is where the line crosses the Y axis when X = 0.
(X,Y) -> (0, 5)
The equation of that line looks to be Y = X + 5.
That equation I wrote follows the Y = mx + B format.
The +B is the Y intercept.

yes the 10' wave is the outlier
6×5 would=30 which is the amount of zebras so if you multiply 5×5 you would=25 which is how much elephants there are
Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a = ![\sqrt{(81+16)}](https://tex.z-dn.net/?f=%5Csqrt%7B%2881%2B16%29%7D)
a = ![\sqrt{97}](https://tex.z-dn.net/?f=%5Csqrt%7B97%7D)
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,
![\frac{\text{DC}}{\text{BD}}=\frac{\text{BD}}{\text{AD}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BDC%7D%7D%7B%5Ctext%7BBD%7D%7D%3D%5Cfrac%7B%5Ctext%7BBD%7D%7D%7B%5Ctext%7BAD%7D%7D)
AD × DC = BD²
b × 4 = 9²
b = ![\frac{81}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7B4%7D)
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
Answer: A
Step-by-step explanation:
81 - 1 1/5x
55 The first thing you could do is convert the mixed fraction into an improper fraction.
1 1/5 to an improper fraction is -6/5
Now rewrite the inequality as,
81 - 6/5x
55 Subtract 81 from both sides
-81 -81
-6/5x
-26 Multiply both sides of the inequality by 5
-6x
-130 Divide both sides by -6 and the sign will me flip since your divide both sides by a negative number.
x ≥ 130/6 Convert 130/6 to a mixed fraction
x ≥ 21 2/3
