Given a>0 and b>0, which inequality shows the result of solving -ax/b >/ (c-d) for x?
a)x </ ad-ac/b
b)x </ bd-bc/a
c)x >/ bc-bd/a
d)x >/ bd-bc/a
We will see that the solution of the given inequality is:
Here we have the inequality:
To solve it, we need to isolate x on one side of the inequality.
First, we can multiply both sides for b:
Now we divide both sides by -a, because we are operating with a negative number, we need to change the direction of the greater than or equal to sign, so we will get:
That is the solution to the given inequality.

Answer:
with the points (2,3) and (-1,-9) the answer is y=4x+10
Step-by-step explanation:
you have to do (x1,y1) (x2,y2) thats for each point
the equation to get the slope is y2-y1 divided by x2,x1
to get the y-intercept to plug in one of the points to the slope-intercept equation
y=4x+5
I picked the points (2,3) but you should get the same answer with the other points
3=4(2)=5
3=8+5
3=13
-3+-3
=10 thats your y intercept.
which, in theory, would be the third side of the triangle formed by these three lines, would be 60 feet.
Answer: 1 large door.
Step-by-step explanation:
You know that the lenght of each door for the small cabinets is:
Since the lenght of the doors for the large cabinets are 3.9 times as long as the doors for the small candidates, the lenght of any of these doors is:
The lenght of the board is 11 feet, so you need to convert it to inches:
Then, the number of large doors that can be cut from that board is:
So, 1 large door can be cut from that board.
b. x = –10
c. x = –8
d.x = 4 or x = 16
The solution to the quadratic equation x² + 20x + 100 = 36 is x = 4 or x = -16 option (a) is correct.
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have an quadratic equation:
x² + 20x + 100 = 36
a = 1, b = 20, and c = 64
After solving:
x = 4 or x = -16
Thus, the solution to the quadratic equation x² + 20x + 100 = 36 is x = 4 or x = -16 option (a) is correct.
