Well, Mathematics can enhance your analytical and problem-solving skills, expands the mind to handle difficult or unfamiliar tasks, and also promotes cautious and careful thinking. Once you know what the words mean you'll be able to write different variable expressions. Like I said it enhances our minds and helps think and solve probelms.

Answer:

r: Slope = 5/4

y-intercept = 2

Step-by-step explanation:

We have the table:

Months, m            Plant height in inches, n

0                           2

2                           4.5

4                            7

6                            9.5

We want a linear relationship to represent this table.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case we can select any pair of points, for example, i will choose the first two:

(0, 2) and (2, 4.5)

Then the slope is:

a = (4.5 - 2)/(2 - 0) = (2.5/2) = 1.25 = 5/4

Then our line can be written as:

y = (5/4)*x + b

To find the value of b, we can replace the values of any of the points in the equation, for example, i will use the point (0, 2) or x = 0, y = 2.

2 = (5/4)*0 + b

2 = b

Then our equation is:

y = (5/4)*x + 2.

Slope = 5/4

y-intercept = 2

[tex] = 1 \frac{1}{5} + \frac{3}{4} - ( - 3 \frac{3}{5} ) - ( - 2 \frac{1}{4} )[/tex]

[tex] = 1 \frac{1}{5} + \frac{3}{4} + 3 \frac{3}{5} + 2 \frac{1}{4} [/tex]

[tex] = (1 + 3 + 2) + ( \frac{1}{5} + \frac{3}{4} + \frac{3}{5} + \frac{1}{4} )[/tex]

[tex] = 6 + ( \frac{4 + 15 + 12 + 5}{20} )[/tex]

[tex] = 6 + \frac{36}{20} [/tex]

[tex] = 1 + 6 + \frac{16}{20} [/tex]

Answer:

The answer is 61/10

Step-by-step explanation:

1 1/5 + 3/4 - (- 3 3/5) - (- 2 1/4)

1 × 5 + 1/5 + 3/4 - (- 3 × 5 + 3/5) - (- 2 × 4 + 1/4)

6/5 + 3/4 + 12/5 + 7/4

6/5 + 12/5 + 3/4 + 7/4

(6 + 12/5) + (3 + 7/4)

18/5 + 10/4

18/5 + 5/2

Now, Cross Multiply

18 × 2/5 × 2 + 5 × 5/2 × 5

36/10 + 25/10 = 61/10

Thus, The answer is 61/10

Step-by-step explanation:

Answer:

20.15

Step-by-step explanation:

Answer:

$776.59

Step-by-step explanation:

For this question, you must use the formula for being compounded continuously. A=Pe^r*t. A stands for your total balance, the part you are trying to find. P stands for the initial amount. E is a constant. R is the rate of interest. And t is the number of years taken. So, to fill in the formula: P is 550, t is 15, and R would be 0.023. For R, remember not to just take the percentage, you must divide the percent of interest by 100, so 2.3 by 100 to get to 0.023. The formula should know be A= (550) e^ (0.023)(15). plug that into your calculator, and you should get $776.59.

Answer:

18

Step-by-step explanation:

3x6 = 18

Step-by-step explanation:

3x + 5y = 15

x + y = 7

This can be written as ,

3x + 3y = 21

Subtracting i and iii ,

5y - 3y = 15 -21

2y = -6

y =-6/2

y = -3

So that ,

x = 21 - 3*-3 /3

x = 21 +9/3

x = 30/3

x = 10

Answer:

$0.13 per lb

Step-by-step explanation:

The slope of a line between these two points is 0.13.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that A hamster weighs half a pound and costs $2 per week to feed.

Labrador Retriever weighs 62.5 pounds and costs $10 per week to feed.

Let x be the weigh and y be the feed cost.

The two points of lines are (0.5, 2) and (62.5, 10)

m=10-2/62.5-0.5

m=0.13

Hence, the slope of a line between these two points is 0.13.

Answer: 0,06?

Step-by-step explanation:

The probability of having both lab work and a referral is 0.94

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

It is given that the probability of having neither lab work nor referral to a specialist is 0.21.

The probability of having lab work is 0.41 and the probability of having a referral is 0.53.

The probability of having both lab work and a referral;

0.41 + 0.53

= 0.94

Therefore, The probability of having both lab work and a referral is 0.94
