Answer:
Step-by-step explanation:
1) Split the second term in into two terms.
1- Multiply the coefficient of the first term by the constant term.
to -8 and multiply to -−20?
2 and −10
3 - Split -8x as the sum of 2x and -10x.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term .
4) Solve for .
1 - Ask: When will (2x+1)(2x-5) equal zero?
When 2x + 1 = 0 or 2x - 5 = 0
2 - Solve each of the 2 equations above.
30 mi/h= 180 mi/min= 950400 ft/min
The last step is
using the budget
Answer:
The solution is (2, 10)
Step-by-step explanation:
In order to solve this system of equations, multiply the second equation by 2, then add through. This will allow the x terms to cancel.
10x + 3y = 50
-10x - 2y = -40
---------------------
y = 10
Now that we have y, plug in and find x.
-5x - y = -20
-5x - 10 = -20
-5x = -10
x = 2
