Answer:
2(x-9) = 2
Step-by-step explanation:
Difference indicates subtraction:
The difference of a number and
9
is
(
x
−
9
)
Twice the difference means
2
(
x
−
9
)
We know that the answer to this is
2
, so as an equation:
2
(
x
−
9
)
=
2
If you solve it we would have:
x
−
9
=
1
←
÷
2
x
=
1
+
9
x
=
10
The difference between
10
and
9
is
1
and twice
1
is
2
.
The number is correct.
Note that written as:
The difference of twice a number and
9
would have a different expression. This would be
2
x
−
9
Answer:
b = -4
Step-by-step explanation:
Well we already have m which is slope which is -1.
And if we start at (-2,-2) and go down using the slope we get -4 as the y intercept or b.
<em>Thus,</em>
<em>-4 is the y intercept or b.</em>

Answer:
D. She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.
Step-by-step explanation:
Find the rate of change between first two ordered pairs and the second two ordered pairs:
1. Points (2,4) and (3,9). Rate of change:
2. Points (3,9) and (4,16). Rate of change:
The rate of change for the linear function must the same for each two points on the graph of the function. In this case, the reate of change differs, so this function is not linear and correct option is D.
We have constructed the frequency distribution.
What is a frequency distribution?
In statistics, a frequency distribution is a graph or data set that shows the frequency of occurrence of each possible outcome of a repeatable event observed many times. Simple examples are election returns and test scores listed by percentile. A frequency distribution can be represented graphically as a histogram or a pie chart.
The frequency distribution table is shown below
Dormancy Period Frequency
55-59 1
60-64 0
65-69 1
70-74 4
75-79 0
80-84 7
85-89 3
90-94 5
95-99 4
100-104 3
105-109 1
110-114 0
115-119 1
N=30
Hence, we have constructed the frequency distribution.
