Answer:
see explanation
Step-by-step explanation:
(a)
To find the x- intercepts , let y = 0 , that is
6x - x² = 0 ← factor out x from each term
x(6 - x) = 0
Equate each factor to zero and solve for x
x = 0
6 - x = 0 ⇒ x = 6
Coordinates of P (6, 0 )
(b)
The axis of symmetry is a vertical line, positioned at the midpoint of the zeros
x = 
= 
= 3
Equation of axis of symmetry is x = 3
(c)
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = 6x - x² = - x² + 6x ← is in standard form
with a = - 1, b = 6 , then
= - 
= 3
Substitute x = 3 into y = 6x - x² for y- coordinate
y = 6(3) - 3² = 18 - 9 = 9
coordinates of maximum point = (3, 9 )
Answer:3x-4y
Step-by-step explanation:
To express the sum of (2x-5y) and (x+y),
We are going to have
2x-5y+x+y
The next thing to do is to collect the like terms;
Then we have;
2x+x-5y+y
Answer realized will now be
3x-4y
Answer: The number was 9.
Step-by-step explanation:
Let the number be 'x;.
think of a number, multiply it by five and subtract three from the result :
According to Ashton, the expression would be :
Kamir tells Andrew to think of a number, add five and multiply the result by three:
According to Kamir, the expression would be :
At last, they get the same number :
Hence, the number was 9.
