Answer:
a)1
b)1/5
Step-by-step explanation:
a)
m=y2-y1/x2-x1
m=4--2/5--1
m=6/6
m=1
b)
m=y2-y1/x2-x1
m=1--2/13--2
m=3/15
m=1/5
<u>Answer</u>
x ≥ -2
<u>Explanation</u>
The inequalities are solve the same way as algebra. This would be solve as follows.
-2x-1≤5
-2x≤5+1
-2x≤4
Divide both sides of the inequality by -2. This will change the sign from ≤ to ≥.
(-2x)/(-2) ≤ 4/(-2)
x ≥ -2
(a-b)¹²=a¹²-12a¹¹b+...
Let a=2r and b=3s then the second term is -12(2r)¹¹(3s)=-73728r¹¹s.
Answer:
x=2
y=2
x=1.3 or 4/3
y=-4
Step-by-step explanation:
Answer:the equations are
x + y = 8
20x + 110y = 340
Step-by-step explanation:
Let x represent the number of commercials on which Alexa's songs were played.
Let y represent the number of movies on which Alexa's songs were played.
The total number of movies and commercials on which Alexa earned is 8. It means that
x + y = 8 - - - - - - - - - - - -1
Alexa will earn $20 every time one of her songs is played in a commercial and $110 every time one of her songs is played in a movie. Alexa earned a total of $340 in royalties. This means that
20x + 110y = 340 - - - - - - - - - - - -2
