Answer:
![\sf x = \dfrac{n - 2mp}{2m}](https://tex.z-dn.net/?f=%5Csf%20x%20%3D%20%5Cdfrac%7Bn%20-%202mp%7D%7B2m%7D)
Step-by-step explanation:
![\sf 3m = m + \dfrac{n}{p + x}\\](https://tex.z-dn.net/?f=%5Csf%203m%20%3D%20m%20%2B%20%5Cdfrac%7Bn%7D%7Bp%20%2B%20x%7D%5C%5C)
![\sf 3m - m = \dfrac{n}{p +x}](https://tex.z-dn.net/?f=%5Csf%203m%20-%20m%20%3D%20%5Cdfrac%7Bn%7D%7Bp%20%2Bx%7D)
![\sf 2m = \dfrac{n}{p +x}](https://tex.z-dn.net/?f=%5Csf%202m%20%3D%20%5Cdfrac%7Bn%7D%7Bp%20%2Bx%7D)
Now cross multiply,
2m*(p +x) = n
To open the parenthesis, multiply 2m by p and x.
2mp + 2mx = n
Isolate the term with variable 'x'
2mx = n - 2mp
Now, isolate 'x', by dividing both sides by 2m
Answer:
Look for where both functions have the same y value. For example, when x = 3 in #7, both are 5. So the solution is (3,5).
Step-by-step explanation:
Each table has two functions. This forms a system of equations. A system of equations is essentially two conditions that must both be met to produce a solution. A solution can be found as where the two equations are equal. In the table, look for where both functions have the same y value for some x. This will be where the values are the same in the same row. This is the solution and is written as an (x,y) point.
7. When x = 3 both functions are 5. The solution is (3,5).
Answer:
x=-6
y=3
Explanation:
y=-4x-21
8x+8y=-24
y=-4x-21
8x+8(-4x-21)=-24
y=-4x-21
-24x-168=-24
y=-4x-21
x=-6
y=-4(-6)-21
x=-6
y=3
x=-6
(-6,3) this is in point form in case you need it
I assume we are writing the equation. The sum of a number and 14 is less than or equal to three times the number.
Let's put in a few values.
The sum of a number = x and + 14 is less than < or equal to = three times 3 * the number.
Now we have: x + 14 is < or = 3 * the number.
We can just remove the "is" and "or", because this is normal math patterns.
x + 14 <= 3 * the number.
"The Number" is referring to the "a number" at the very beginning. So we can replace that with the same variable.
x + 14 <= 3x
Answer:
-3/2, -3/5, 3/5, 3/2
Step-by-step explanation:
-3/2 Is The Leastest Number Beacuse It Has A Negative Number And -3/2 = -1.5
-3/5 Is The Second Least Number Because -3/5 > -3/2, It Is Also A Negative As Well As -3/2
3/5 Is The Second Greatest Number Because It Is A Positive Number And 3/5 = 0.6
3/2 Is The Greatest Number Because 3/2 > 3/5, It Is Also A Positive Number As Well As 3/5.
