Answer:
Slope: 0
Step-by-step explanation:
We have to find the slope of the line with the given points.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.
Plug in your coordinates and solve.
Solve:
m = -7 - (-7)/-2 - 4
m = -7 + 7/-2 - 4
m = 0/-6
Divide -6 from 0.
m = 0
You would notice that we have a "0" in our slope. There is no "rise" in the slope.
This means that the slope of our line would be 0.
50 ounces of 15% saline solution contains 0.15*50 = 7.5 ounces of salt.
Let x be the amount of pure water you add to this solution. Then you end up with (x + 50) ounces of this new solution. The amount of salt stays the same.
You want the new solution to have a concentration of 10%. This means you need
7.5 / (x + 50) = 0.1
==> 7.5 = 0.1(x + 50)
==> 7.5 = 0.1x + 5
==> 2.5 = 0.1x
==> 2.5/0.1 = 0.1x/0.1
==> x = 25
Answer:
A. 5000 B: 12000 C 57000
Step-by-step explanation:
All you need to do is look at the hundreds place number and if it is below 4 or is 4 keep the number the same, if it is above 4, increase it by one.
Answer:
How do you describe the solution set to a system of linear inequalities?
Step-by-step explanation:
The solutions of a system of linear inequalities are all the ordered pairs that make all the inequalities in the system true.
The area of a parallelogram is:
A = b * h
Where,
b: base
h: height
Clearing the base we have:
b = A / h
Substituting values we have:
b = (6x2 + x + 3) / 3x
Rewriting we have:
b = 2x + 1 / x + 1/3
Answer:
the length of the base is:
b = 2x + 1 / x + 1/3
