Thank you.

Answers

Answer:

Step-by-step explanation:

The tree is 5/8 meters tall and that's in 1 2/5 years so you would divide them and you get .4464287142

0.4 or 0.4464287142

Which value of x makes the equation true?
−4=1.5x+5

Answers

Answer:

For x = -6

Step-by-step explanation:

1.5x + 5 = -4

1.5x = -4 - 5

1.5x = -9

x = -6

Checking: 1.5 * -6 + 5 = -4

x = -6


1. You subtract 5 to both sides
2. divide 1.5 to the other number

For the past ten years, Michelle has been tracking the average annual rainfall in Boynton Beach, Florida by recording her data in the given table. She has concluded that the relationship can be modeled by a linear function.

Year 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013
Average Rainfall(in inches) 62.33 61.8 61.27 60.74 60.21 59.68 59.15 58.62 58.09 57.56
Use the values provided in the table to create a linear graph of the data. On the graph, let x = 0 represent the year 2004. Be sure to include all proper labels on the graph.

Answers

Answer:
55.44 inches
Step-By-Step Explanation
part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.
slope = m = (change in rainfall)/(change in years)
= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53
then the point-slope form of the equation of the line can be written as
y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)
y = -0.53x +62.33 . . . x = years after 2004
part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is
y = -0.53·13 +62.33 = 55.44 . . inches
the predicted rainfall in 2017 is 55.44 inches.

The linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]

What are linear functions?

A linear function is a graph that has a constant rate.

From the table, we have the following ordered pairs

(x,y) = (0,62.33) and (1, 61.8)

Start by calculating the slope (m)

[tex]m = \frac{y_2 -y_1}{x_2-x_1}[/tex]

So, we have:

[tex]m = \frac{61.8 -62.33}{1-0}[/tex]

[tex]m = -0.53[/tex]

The linear equation is then calculated as:

[tex]y = m(x -x_1) + y_1[/tex]

So, we have:

[tex]y = -0.53(x -0) + 62.33[/tex]

Expand

[tex]y = -0.53x + 62.33[/tex]

Hence, the linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]

Answers

Answer:

The numbers are 44 and 36

Step-by-step explanation:

n + n - 8 = 80

2n - 8 = 80

2n (- 8 + 8) = 80 + 8

2n = 88

2n/2 = 88/2

n = 44

44 - 8 = 36

Numbers are 44 and 36 they have a difference of 8 and combine to make 80

Subtract the sum of three test scores from the product of 75 and 5 .
I think

Answer:

Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.

Step-by-step explanation:

From the question:

100, 70, 85 on three of her five tests

Total number of test = 5

mean of the five scores is 75

mean = average of the five scores

Average score = Total score / total number of test

Total score = Average score * total number of test

= 75*5 =375

to find remaining two tests' scores

Total score - the 3 scores from question

= 375 - 100 - 70 - 85

=120

If u want to find the score of each of the unknown test

From question:

She could not remember the other two scores, which were the same.

Thus,

The score of one test

= 120/ 2

=60
