Answer:
Step-by-step explanation:
use uv rule= uv'+vu'
u=3x+7
u'=3+0=3
v=8x-5
v'=8-0=8
uv= (3x+7)(8)+(8x-5)(3)
=24x+56+24x-15
=48x+41
Answer:
Step-by-step explanation:
We are given the following in the question:
Let l be Lyle's height, h be Harry's height and v be Vince's height.
Thus, we can write:
Lyle's Height =
Harry's height =
Putting the value in the equation:
Thus, Vince's height is 3.5 feet.
The correct answer is x>-2. The graph is attached.
To solve this:
-x/2 + 3/2 < 5/2
Subtract 3/2 from both sides:
-x/2 + 3/2 - 3/2 < 5/2 - 3/2
-x/2 < 2/2
-x/2 < 1
Multiply both sides by 2:
(-x/2)*2 < 1*2
-x < 2
Divide both sides by -1:
-x/-1 < 2/-1
Remember to flip the the symbol since you divide both sides by a negative:
x > -2
To graph the inequality, we draw a number line, making sure we have -2 on it. We circle -2 and leave it open, since it is strictly greater than. Then we shade the line to the left.
If we have to divide the balloons equally among the children, but we can, not can't, have leftover balloons, we can just divide the total number of balloons, 13, by 3 children.
13/3 = 4 1/3
We have 1 balloon remaining, but that's okay. We gave the maximum number of balloons to each child, which is:
4 balloons, or the answer B.
