Answer:
60≥20x+50y
Step-by-step explanation:
Let x = notebooks and y = pens (all per week)
One solution would be x ≥ 1 and y ≥ 1 as at least one per each item per week
Step 1
Graph the function using the values in the table
Step 2
Find the quadratic function that best fits the data set from the graph

Hence,
Answer:
= 15x +30y -220
Step-by-step explanation:
We can easily get another expression if we multiply each individual term, and
add together the result
30(1/2x-2)+40(3/4y-4)
= 15x-60 +30y-160
= 15x +30y -220
See attached picture below
Sum of <span>supplementary = 180
180 - 35 = 145
145/2 = 72.5
so
one angle = 72.5
and
its supplement = 72.5 + 35 = 107.5
