Additive property of zero describes this number sentence.
The meaning of this property is that zero added to any whole number results into the number itself.
Answer:
plug each half of the ordered pair into the variable term. (x,y)
Step-by-step explanation:
For example (---,20) y=5x 20=5x divide by 5 on both sides 20/5= 4 x=4
1. y=f(x)=170x-4 is a function with variable x representing a year.
2. Let's consider the difference between 2 consecutive years, say year 3 and year 4
f(3)=170*3-4
f(4)=170*4-4
we expect f(3)-f(4) to be 4 since after 4 years, the water will be 4 feet less than after 3 years.
check: f(3)-f(4)=(170*3-4)-(170*4-4)=170*3-4-170*4+4=170*3-170*4=170*(3-4)=170*(-1)=-170
Answer:
∠ 2 = 48°
Step-by-step explanation:
the 2 angles form a right angle = 90°
sum the 2 angles and equate to 90°
∠ 2 + 44° = 90° ( subtract 44° from both sides )
∠ 2 = 48°
Answer:
Frequency
Step-by-step explanation:
"A dot plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value. The total number of dots in the plot is the total number of values in the data set. The data points must all be in the same units."
