Answer:
Step-by-step explanation:
Solve for n:
i)
Axis of symmetry:
x = - 2 (the value of x vertex)
ii)
Vertex:
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
The vertex (-2, -4)
iii)
Domain:
All real number
iv)
Range: y >= - 4 (the vertex is the lowest point on the graph, it has minimum value and opens up)
Solution to the system of linear equations is (5/3, -14/3)
Step-by-step explanation:
- Step 1: The system of linear equations are
8x + 2y = 4 ------ (1)
16x - y = 18 ------ (2)
- Step 2: Multiply eq(2) by 2 to make coefficients of y equal
8x + 2y = 4
16x - 2y = 36
- Step 3: Add the two equations
⇒ 24x = 40
⇒ x = 40/24 = 5/3
- Step 4: Find the value of y
⇒ 8 × 5/3 + 2y = 4
⇒ 40/3 + 2y = 4
⇒ 2y = 4 - 40/3 = -28/3
⇒ y = -14/3
increase the speed is definitely the answer
So, the age of the aunt is 57 which is 17 years above 40 and the age of west is >>x-14=43 >> 43 which is 17 years below 60
