Answer:
x < 9
Step-by-step explanation:
Writing this entirely with symbols, we get:
-5(x - 1) > -40
We must solve for x.
Carrying out the multiplication, we get:
-5x + 5 > -40, or
-5x > -45
Dividing both sides by -5 isolates x:
x < 9
Note that when working with an inequality such as this one, dividing both sides by a negative number requires changing the direction of the inequality symbol.
2x+3=3x-4
try to isolate the x term
you must do the same thing to both sides or else it won't be equal anymore
2x+3=3x-4
add 4 to both sides
2x+3+4=3x+4-4
2x+7=3x+0
subtract 2x from both sides
2x-2x+7=3x-2x
0+7=x
7=x
the answer is x=7
Answer:
Choice C is correct.
Step-by-step explanation:
put point A in (x+1,y-3)
now (-6,4) becomes (-5,1).
put point C in (x+1,y-3)
now (2,1) becomes (3,-2)
put point B in (x+1,y-3)
now (-3,-2) becomes (-2,-5).
4b+20 because you disrepute the 4
