Just multiply each term by -4 and add/subtract the remaining terms as necessary:
-4(6x)-4(-4v)-4(-1)= -24x + 16v +4
Answer:the company bought 12 computers and 4 printers.
Step-by-step explanation:
Let x represent the number of computers that the company bought.
Let y represent the number of printers that the company bought.
The company buys a total of 16 machines. It means that
x + y = 16
Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that
550x + 390y = 8160 - - - - - - - - - - 1
Substituting x = 16 - y into equation 1, it becomes
550(16 - y) + 390y = 8160
8800 - 550y + 390y = 8160
- 550y + 390y = 8160 - 8800
- 160y = - 640
y = - 640/ - 160
y = 4
Substituting y = 4 into x = 16 - y, it becomes
x = 16 - 4
x = 12
Answer:
g(x+2) means that x + 2 is going into g(x).
Step-by-step explanation:
Given:
g(x) = x^2 - x
g(x + 2)
g(x+2) means that x + 2 is going into g(x)
x = x + 2
Substitute:
g(x + 2) = (x + 2)^2 - (x + 2)
Solve:
g(x + 2) = (x + 2)^2 - (x + 2)
= x^2 + 4x + 4 - (x + 2)
= x^2 + 4x + 4 - x - 2
Simplify:
g(x + 2) = x^2 + 3x + 2
Answer:
Step-by-step explanation:
First find the slope of the line that passes through the points (-5,0) and (-1, -8). Notice how x increases 4 units from -5 to -1 and y decreases 8 units.
Thus, the slope of this line is m = rise / run = -8/4, or m = -2.
Another way to look at this:
change in y - 8 - 0
m = -------------------- = ------------ = -2
change in x -1 - (-5)
Please note: m=-1 - (-5) = 45
8 = -2 is not correct; 8 cannot equal -2.
