1/(square root)2=(square root5)/x
X=(square root 2) x (square root 5)
X=(square root 10)
Answer:
- 45
Step-by-step explanation:
let n be the number , then
n - 11 = n + 4 ( add 11 to both sides )
n = n + 15 ( multiply through by 3 to clear the fraction
2n = 3n + 45 ( subtract 2n from both sides )
0 = n + 45 ( subtract 45 from both sides )
- 45 = n
The number is - 45
Answer:
y = -4/5x - 0.8
Step-by-step explanation:
A(-6, 4)
B(4, -4)
Find slope using the two points above:
m = (y₂ - y₁) / (x₂ - x₁)
= (-4 - 4) / (4 - (-6))
= -8 / 10
m = -4/5
Find y-intercept using m from above and anyone point, let's use (-6, 4):
y = mx + b
4 = -4/5(-6) + b
4 = 24/5 + b
b = -0.8
Use m and b from above to form equation of line:
y = mx + b
y = -4/5x - 0.8
Answer:
x = -2
Step-by-step explanation:
In order to find the axis of symmetry, we will have to find the x-value of the vertex.
Vertex = (-b/2a, f(-b/2a))
In x² + 4x + 6,
a = 1 , b = 4 , c = 6
Vertex = (-4/2,f(-4/2))
Vertex = (-2,f(-2))
We have found the x-value of the vertex which is -2.
Hence, line/axis of symmetry is x = -2
