Answer:
D) 
, 
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation : 
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is
The blue boundary line passes through the origin and has slope 
.
Its equation is 
Since the boundary line is not solid and the right half-plane is shaded, its inequality is
The correct choice is D.
Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>
</u>
To find initial price make t=0
Initial price: 1200
It represents growth because 1.025>1
It changes by 1.025*100=102.5% a year.
The answer is B
If the sweater is on sale for 20%, then the sale price will be 80% of the regular price.
Therefore, $60 = 80% of regular price
$60/80 = $0.75 which gives you 1% of the regular price
So $0.75 is 1% of regular price.
$0.75 * 100 = $75 which gives you the regular price as 1% multiplied 100 times = full price
Soooo, full price is b.) $75
