Answer:
14 km
Step-by-step explanation:
6 km in the afternoon
x km in the morning
6= x- 25%
6= 0.75x
x= 6/0.75
x= 8 km
total 6+8= 14 km
Answer:
D. (-3;-3)
Step-by-step explanation:
2x-3y<9
A. 2×6-3×(-4)=24 FALSE, because 24>9
B. 2×(-1)-3×(-9)=25 FALSE, because 25>9
C. 2×2-3×(-5)=11 FALSE, because 11>9
D. 2×(-3)-3×(-3)=9 TRUE, because 3<9
Step-by-step explanation:
Discrete data can only have certain values. For example, if you roll a die, there are only 6 numbers you can get. Continuous data can have any value within a range.
Graphically, discrete data will appear as only points, where as continuous data appears as a line or curve.
So the top left and bottom right graphs are discrete. The top right and bottom left graphs are continuous.
To be a function, each x value can only have 1 y value. Graphically, we can check this using the "vertical line method". Imagine a vertical line (or use a ruler or straight edge) and move it from left to right. If it ever crosses the graph in two or more places, the graph is not a function.
Therefore, the graphs on the left are not functions, and the graphs on the right are functions.
Answer:
B.
Step-by-step explanation:
Answer:
$28.20
Step-by-step explanation:
Let's set up an equation.
Let b be the cost of a bumper sticker.
Since the sum of the prices of 11 bumper stickers total up to $10.34, we can set up an equation!
11b = 10.34
Dividing by 11 on both sides,
b = 0.94
Plugging in b into 30b,
30(0.94)
We get
$28.20
