If you are suppose to find how much the spent all together then it would be 21. 09
Answer:
5a + (-6a) + (-2b) + 2b + (-3) = -a -3 or -(a + 3) so first answer is correct because -(a + 3) is the same as -(3 + a)
Step-by-step explanation:
Answer:
-1.2
Step-by-step explanation:
Given that the designer also programs a bird with a path that can be modeled by a quadratic function.
The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).
If we treat this curve as line joining these two points then we can find the slope by the formula
Slope = change in y coordinate/change in x coordinate
Here the points given are
(0,20) and (10,8)

Slope of the line that represents the turtle's path
=-1.2
Total number of songs in Julie's MP3 player = 860
Percentage of rap songs in Julie's MP3 player = 20%
Then
Number of rap songs in Julie's MP3 player = (20/100) * 860
= 860/5
= 172
Percentage of R&B songs in Julie's MP3 player = 15%
Then
Number of R&B songs in Julie's MP3 player = (15/100) * 860
= 1290/10
= 129
So
The number of other types of songs in Julie's MP3 player = 860 - (172 + 129)
= 860 - 301
= 559
So the number of other types of songs in Julie's MP3 player was 559.
Answer:
0.5x+0.3y >= 3
sorry I don't know how to make the less than or equal to sign
Step-by-step explanation:
he can buy X amount of gumballs if he buys Y amount of jawbreakers and that will be less than or equal to $3
to graph, you must plug the number 0 into the X spot and solve.
0.5(0) +0.3y >= 3
next plug in for Y
0.5x+0.3(0) >= 3
plot these two points on the graph and draw a line through them
