Answer:
First equation solution:
x≤4
Second equation solution:
x≥4
Step-by-step explanation:
1/2x+8≤ 10
subtract 8 from each side
1/2x≤ 2
multiply each side by 2
x≤ 4
-3x-24≤- 36
add 24 to each side
-3x≤ -12
divide by -3 ( when dividing or multiplying by a negative number the </>/≤/≥ flips)
x≥4
Answer:
(x-5) (x+4)
Step-by-step explanation:
x^2 -x -20
What two terms multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
(x-5) (x+4)
Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together
4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:
4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)
so the problem is this: 4s+12=2(s+2)
now you solved it and the answer will beeeeee s=-4
