Answer: the missing values are 7, 28 and 14
Step-by-step explanation:
In a proportional relationship, there is a constant relationship between the given variables. Thus, for any change in the value of one variable, there is a corresponding change in the value of the other variable.
The table shows a proportional relationship between values of servings
12 ,4 16 ,8
and values of ounces
21 ? ? ?
Let the missing values be x, y and z
Therefore,
21/12 = x/4
1.75 = x/4
x = 4 × 1.75
x = 7
21/12 = y/16
y = 16 × 1.75 = 28
21/12 = z/8
z = 1.75 × 8 = 14
Answer:
25%
Step-by-step explanation:
2/8 = 1/4 = 0.25 = 25%
Answer:
Step-by-step explanation:
First find the slope of the given line.
y - 3 = 1/3(x+2)
y - 3 = (1/3)x + 2/3
y = (1/3)x + 2/3 + 3
y = (1/3)x + 11/3
Compare it with
y = mx + c
We get m = 1/3
As the parallel lines have same slope, the slope of the second line will also be m= 1/3
y = mx + c
y = (1/3)x + c
As this line goes through the point (1,7), substitute it in the equation:
7 = (1/3)1 + c
7 = 1/3 + c
c = 7 - 1/3
c = 21-1/3
c = 20/3
The equation of the line is found by substituting m = 1/3 and c = 20/3 into the general equation
y = mx + c
y = (1/3)x + 20/3
Graph of the equation is shown
