Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.

Answer:
x+y<20andx+5y>40
Step-by-step explanation:
The inequality for the number of coins is ...
x + y < 20
The inequality for the value of the coins is ...
x + 5y > 40
Step-by-step explanation:
for a
- a+,38°=90°{ angle at circumference through center is 90°}
- a=90-38
- a=52°
for e
- e=38°{base angle of isosceles triangle r equal}
for d
- 38°+e+d=180°{sum of angle of triangle}
- d=180-76
- d=104°
for. c
- c+d=180°{straight angle}
- c=180-104°
- c=76°
for b
- a+b+c=180°{sum of angle of triangle}
- b=180-128
- b=52°
