4 - (x + 2) < -3(x + 4)
4 - x - 2 < -3(x) - 3(4)
4 - x - 2 < -3x - 12
-x + 2 < -3x - 12
2x + 2 < -12
2x < -14
x < -7
The answer is A.
Answer:
Step-by-step explanation:
Given is a function
Since leading term is positive,
the parabola is open up.
Let us write this in vertex form after completing the square
Hence we get vertex= (-5/2,-1/4)
Since this is a parabola open up we have the minimum point is only one at x=-5/2
So we have the function decreasing for x<-2.5 and increasing for x>-2.5
Decreases in
Increases in
Answer:
I can't see the whole problem but if it says how many times per week does he practice it would be 13 times
Step-by-step explanation:
9 3/4 divided by 3/4.
39/4 times 4/3=13
Answer:
$70.88
Step-by-step explanation:
He bought the boots for $80*75% = $80*0.75 = $60
Let x = the original price of the belt
He spent x * 85% = 0.85x for the belt
total cost = 60 + 0.85x = 120.25
0.85x = 120.25 - 60 = 60.25
x = 60.25/0.85 = $70.88
