The total cost is the initial fee plus the cost of the boxes.
12 + 5×3.99 = 31.95
Answer:
B
Step-by-step explanation:
(-2,4), (0,6), and(2,8)
Answer:
Yes
Step-by-step explanation:
If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:
ECM = 3x + 15
becomes
90 = 3x + 15
75 = 3x
25 = x
ACE = 4x - 10
becomes
90 = 4x - 10
100 = 4x
25 = x
Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees
Answer:
t = -2
Step-by-step explanation:
5t - 26 = 18t
Add 26 to both sides:
5t - 26 + 26 = 18t + 26
Simplify:
5t = 18t + 26
Subtract 18t from both sides:
5t - 18t = 18t + 26 - 18t
Simplify:
-13t = 26
Divide both sides by -13:
-13t/-13 = 26/-13
Therefore:
t = -2
I hope this helps!
