Expression 56k³ - 84k² + 70k - 105 can be simplified to: 7(8k³ - 12k² + 10k - 15)

8k³ - 12k² + 10k - 15 is a third degree expression. it will be factorised to:
(k - 1.5)(k + 2.2)²

Finally expression 56k³ - 84k² + 70k - 105 can be simplified to: 7(k - 1.5)(k + 2.2)²

Good luck

I don’t know this please help
Brrunno [24]

The Y-intercept is where the line goes through the Y-line. In this case, the Y-intercept is -3.

Slope is y2-y1/x2-x1

(5,6) (0,-3)

6-(-3)=9

5-0=5

9/5 is the slope.

Suppose r(x) and t(x) are two functions with the same domain, and let h(x)=r(x)+t(x).
Sphinxa [80]

Answer:

If the maximum of function r(x) and t(x) occur at the same point c in domain P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

Step-by-step explanation:

If the maximum of function r(x) and t(x) occur at the same point c in domain then M=r(c) and N=t(c) So in this case P = max(r(x)+t(x)) = M+N

In general P  ≤  M+N

by definition of maximum  

r(x)≤M,t(x)≤N   for all x in domain

=>  r(x)+t(x)≤M+N   for all x in domain

=> max(r(x)+t(x)) <= M+N

=> P  ≤  M+N

Thus we get in general the relationship is P  ≤  M+N

The sum of a number and three is less than nineteen less the number
galina1969 [7]

Answer: x < 8

Step-by-step explanation:

Let the number = x + 3 ( sum) first sentience, continuation,

x + 3 < 19 - x , second sentience.

Now solve for x

Collect like terms

x + x < 19 - 3

2x < 16, divide through by 2

x < 8.
