Answer:

NUMBER 2) x>_3/7

Step-by-step explanation:

-2(2-2x)-4(x+5) is less than or equal to -24

-2(2-2x)-4(x+5) <_ -24        Divide the expression by the #'s outside the ()

2-2x+x+5>_-3                     This is the quotient from dividing it by -8 (-2 and -4)

(when you divide by a negative number, the signs flip)

7-x>_-3                                Now, divide both sides by 7

-x>_-3/7                              If you want, convert to a decimal. Lastly, divide by -1

x>_3/7

2. The expression x + 3x- kx + 4 has a remainder of k when divided by x - 2. Find the value of k.​
Natasha2012 [34]

Answer:

4

Step-by-step explanation:

the above question simply means that

{X+3X-K X+4} - k

is exactly divisible by (X -2)

to find the value of K, put X= 2

2+3(2)-K(2)+4-k=0

2+6-2K+4-K = 0

12-3K = 0

12 = 3K

K = 12/3 = 4

K= 4
