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:
−25x+54−32rx+64r−x^2
Step-by-step explanation:
(−28−32r−x+1)(x−2)
Add −28 and 1 to get −27.
(−27−32r−x)(x−2)
Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.
−27x+54−32rx+64r−x^2+2x
Combine −27x and 2x to get −25x.
−25x+54−32rx+64r−x^2
For the 1st one, shade the entire 1st row of squares.
For the 2nd, shade the bottom right square.
Answer:
C and D are equivalent.
Step-by-step explanation:
if you multiply 7/6 both by 2 it will =14/2 and also if you multiply 7/6 both by 10 you will get 70/60.
