- (x, y) = (1/2, 4)
- (x, y) = (2, 10)
Step-by-step explanation:
1. No link, no question
__
2. Divide the first equation by 2 and substitute for y using the expression in the second equation.
2x +(4x+2) = 5
6x = 3 . . . . . . . . . subtract 2
x = 3/6 = 1/2 . . . . divide by2
y = 4(1/2) +2 = 4 . . . . substitute into the equation for y
The solution is (x, y) = (1/2, 4).
__
3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
Answer:
$450
Step-by-step explanation:
1050 - (12 x 50) = 450
12 x 50 = 600
1050 - 600 = 450
Answer:
In mathematics, a function on the real numbers is called a step function (or staircase function) if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant function having only finitely many pieces.
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
C because your looking for y*48 which is 48y. It is c because (y*40)+(y*8) gives you 40y+8y which equals 48y.
Answer:
increasing
Step-by-step explanation:
Since the line goes up from left to right, the graph is increasing
