Answer:
x<48.84
Step-by-step explanation:
all work is shown
I think its <span>√5, but I'm not entirely sure. </span>
<span>a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.
b) are there any restrictions on the variables?
The total sum of both activities must be equal or less than $80 a month
c) write a linear inequality to represent this situation
</span><span>Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.
5x + 4y <u><</u> 80
You can graph linear inequality using these coordinates.
x y
16 0
12 5
8 10
4 15
0 20</span>
Y - (-5) = -7
y + 5 = -7
y = -7 - 5
y = - 12 <==
(3•b)^10. 3 times b them after you do that, you put that answer to the 10th power
