This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
Answer:
y = -6x + 2
Step-by-step explanation:
Slope intercept form: y = mx + b
m is the slope
b is the y-intercept
The line pictured goes down 6 for each 1 it moves to the right, slope is rise over run, in this case, -6/1 or just -6
The y-intercept is the point that the function crosses the y-axis, in this case 2
Plug those in to get:
y = -6x + 2
Vertical line, because it doesn't have an x-coordinate unit of change so the line would just be straight and vertical along the graph (0, 7).
