Use the Factor Theorem to determine if the given binomial is a factor of the given polynomial function: f(x) = 3x^3 +x^2 - 20x+12, x+3. (-3) = 0; the binomial is not a factor of the polynomial.
(3) = 0 : yes, the binomial is a factor of the polygomial
.
(-3)=0; yes, the binomial is a factor of the polynomial
.
(3) = 0; the binomial is not a factor of the polynomial.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

there were a lot of them but the first one to pop up on a google search was bts
