If you are trying to solve for x, then
4x+5<=13
subtract both sides by 5
4x<=8
then divide both sides by 4
x<=2
Yes a factor is less then the number and the multiple it greater, for example 6 a multiple is 12,24, and so on...
Im not sure but it think its 410 mile long, idk double check by changing it into eighths

Step-by-step explanation:
a) Let y = f(x) = 3x - 2x^2
f(-2) = 3(-2) - 2(-2)^2 = p
= -6 - 8
= -14
= p
f(2.5) = 3(2.5) - 2(2.5)^2 = q
= 7.5 - 12.5
= -5
= q
b) graphing
c) From the graph, you should be able to verify the following:
i) f(0.5) = 3(0.5) - 2(0.5)^2 = 1
ii) 0.5 = 3x - 2x^2 or x = 1.3, 0.2
iii) the maximum occurs at
f(0.75) = 1.125
d) the equation for the line of symmetry is x = 0.75
