The answer comes from using proportions. 3lbs to 14 people. Turn that into a fraction, then make a second fraction with 55 as the denominator. Find a common denominator for both denominator values, and multiply the numerators to find the missing value.
Q4.
Answer: all real numbers greater than or equal to 0.
Q.
The range is read from the y axis. Therefore the range = (-∞ , 1]
Answer: {y | y ≤ 0}
Q.
The first part of the graph has a slope = 2, therefore it's y = 2x.
The second part of the graph is horizontal line y= 4.
Therefore your answer is:
Answer:
The answer is (3,2) or x=3 and y=2
Step-by-step explanation:
Solving the second equation for y..
2x-y=7 divide both sides by -1
y-2x=-7 add 2x to both sides
y=2x-7
When a solution exists, y=y, so we can say:
2x-7=2x+3 subtract 2x from both sides
-7=3
-1 != 3
Since the above is never true, there are no solutions to this system of equations.
Intuitively, this is because both lines have the same slope, they are parallel, and have an different y-intercept, thus they will never cross each other...
Blue squares colored equals 6/8, add that to 1/8 (the red squares), this equals 7/8 which minus 8/8 is 1/8 which is the yellow colored squares
