Answer:
x² = y
Step-by-step explanation:
x² = y fit one input to one output property of function
Answer:
what are you saying .......
About 102 estimate the is the Anwer 102
<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>
Answer:
x = 14
AB = 37
BC = 36
AC = 28
PQ = 28
QR = 28
PR = 45
Step-by-step explanation:
we can add together the sides of ΔABC and set it equal to the sum of the sides of ΔPQR
2x+9 + 2x+8 + 2x = 2x + 2x + 3x+3
combine 'like terms':
6x + 17 = 7x + 3
subtract 6x from each side to get:
17 = x + 3
subtract 3 from each side to get:
14 = x
CHECK:
Does 6(14) + 17 equal 7(14) + 3?
84+17 = 98+3
101 = 101 checks out correctly
