Step-by-step explanation:
= 10x - 5 + 3x - 2
= (10 + 3)x + (-5 - 2)
= 13x - 7
The constant of proportionality of the given graph is gotten as 4.
<h3>How to find the constant of proportionality?</h3>
The constant of proportionality here is simply the slope of the graph.
Now, we will take two points and use their coordinates to find the slope from the formula;
m = (y2 - y1)/(x2 - x1)
Let us pick 2 points which are;
(1, 4) and (2, 8). Thus;
m = (8 - 4)/(2 - 1)
m = 4/1
m = 4
Thus, the constant of proportionality of the graph is gotten as 4.

572 gallons of milk / 52 weeks = 11 gallons of milk / week.
Answer:
71°
Step-by-step explanation:
BDH is a triangle (as seen on figure)
<BDH + <DBH = <DHE ( Sum of two interior angles of a triangle is equal to the opposite exterior angle)
40° + 31° = X
X = 71°
Vertical because the line passed through -4 on the x axis
