5x-y=54
x=10
50-y=54
-y=54-50
y= -4
From the graph, we can say that the system can be represented by a linear function. A linear function has a standard form of:
y = mx + b where m is the slope and b is the y-intercept.
From the image, b would have a value of 48. The slope can be calculated as follows:
slope = ( 48 - 36 ) / (0 - 1) = -12
The equation can be written as:
y = -12x +48
or
12x + y = 48
Answer:
20 bottles for 28
Step-by-step explanation:
15 ÷ 10 = 1.5
28 ÷ 20 = 1.4
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
