Answer:
y = 40 + 0.35x
y = 50 + 0.1x
Step-by-step explanation:
Talk A Lot Company
$40 for 600 mins
$0.35 for each extra min
Total cost = y
Number of extra minutes after 600 mins = x
y = 40 + 0.35x
Chat Away Company
$50 for 600 mins
$0.10 for each extra mins
Total cost = y
Number of extra minutes after 600 mins = x
y = 50 + 0.1x
Answer:
SU = 26 meters
Step-by-step explanation:
Based on the definition of a parallelogram, we know that the diagonals bisect each other, so we know that:
UV = VS
x + 3 = 2x - 7
10 = x
Now that we know "x", we can find the length of SU:
SU = x + 3 + 2x - 7
SU = (10) + 3 + 2(10) - 7
SU = 13 + 20 - 7
SU = 33 - 7
SU = 26 meters
Answer:
2nd Option
3rd Option
Step-by-step explanation:
Linear equations are equations with a variable degree of 1.
Choice 1 is a function and a linear equation
Choice 4 is a linear equation but <em>not </em>a function
Quadratic equations are equations with variable degree of 2
(So choice 2 isn't a linear equation)
Cubic equations are equations with variable degree of 3
(So choice 3 isn't a linear equation)
