Answer:
a) 3
b) 4
Step-by-step explanation:
The point P is(3,4)
which means that 3 is the point P's x- coordinate and 4 is it's y-coordinate
Because we use the axes as our reference point when plotting points,
the distance of P from x-axis and y-axis would be the point itself.
Answer:
80%
Step-by-step explanation:
28/35=4/5
4/5=0.80
0.80=80%
All of these have no x-intercepts, since x-intercepts require y to be 0. Their y-intercepts are:
(0, 4)
(0, -18)
(0, 16)
(0, -7)
respectively.
Answer:
P(x)=(x-2)(x-4)(x+3)(x+6)
Step-by-step explanation:
Given: P(x)=x⁴+3x³-28x²-36x+144
It is a polynomial with degree 4.
It should maximum four factor.
Hit and trial error method.
Put x = 2 into P(x)
P(2)=2⁴+3×2³-28×2²-36×2+144
P(2) = 0
So, x-2 would be factor of P(x)
Now divide x⁴+3x³-28x²-36x+144 by x-2 to get another factors


Put x = 4
now divide
by x-4


Now factor 
Complete factor of P(x)
P(x)=(x-2)(x-4)(x+3)(x+6)
