Ur perpendicular line will have -1 as the slope
y - y1 = m(x - x1)
slope(m) = -1
(2,5)...x1 = 2 and y1 = 5
now sub
y - 5 = -1(x - 2) can be written like : y - 5 = -(x - 2)
Answer:
firstly you know the term of multiplication
like 5*2=10 ,10*2=20, 20*2 =40 and 40*2 =80
and last three numbers are 80, 160,320
For the equation F(x) = ax² + bx + c we have:
- maximum value if a<0
- minimum value if a>0
F(x) = -3x² + 18x + 3 ⇒ a = -3, b = 18
a < 0 ⇒ the function has a maximum value
Quadratic function has the maximum value (or minimum) at vertex of its parabola.
The maximum value is k at x=h where:
and k = F(h)

Therefore:
<h3>
The function has a maximum value of 30 at x = 3</h3>
The ration of x to y is 1:3 if you divide 2:6 by its gcf (2), you get 1:3.
