Circle the difference.
8 -2=6

Answers

you have it correct u would circle that one bc it wants to know what’s the difference between them

The answers are 8 -2 = 6, and  9 – 5 = 4 because there are a total of 8 apples and 2 apples falls from the tree.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

1)

Total number of apples = 8

Number of apples falls = 2

Remaining apples in the tree = 8 – 2 = 6

Mark a circle on  8 -2 = 6

2) Mark a circle on 9 – 5 = 4

Thus, the answers are 8 -2 = 6, and  9 – 5 = 4 because there are a total of 8 apples and 2 apples falls from the tree.

The equation for the line of best fit is: C. y = 0.894x + 0.535.

How to determine the equation for the line of best fit?

In order to determine the equation for the line of best fit, we would create a table of values based on the given x-values and y-values as follows;

x          y            x²        y²          xy__

5          4          25        16       20

6          6           36       36       36

9          9           81        81        81

10         11          100       121       110

14          12        196       144      168  

Sum                  438       398     415

Next, we would calculate the mean of the x and y variables as follows;

Mean = [∑(x)]/n

Mean = 44/5

Mean, [tex]\bar{x}[/tex] = 8.8

Mean = [∑(y)]/n

Mean = 42/5

Mean, [tex]\bar{y}[/tex] = 8.4

∑(x - [tex]\bar{x}[/tex])(x - [tex]\bar{y}[/tex]) = (5-8.8)(4-8.4) + (6-8.8)(6-8.4)+(9-8.8)(9-8.4)+(10-8.8)(11-8.4)+(14-8.8)(12-8.4)

∑(x - [tex]\bar{x}[/tex])(x - [tex]\bar{y}[/tex]) =45.4

∑(x - [tex]\bar{x}[/tex])² = (5-8.8)²+(6-8.8)²+(9-8.8)²+(10-8.8)²+(14-8.8)²

∑(x - [tex]\bar{x}[/tex])² = 50.8

Now, we can determine the slope coefficient for the line of best fit:

Slope (b) = 45.4/50.8

Slope (b) = 0.894.

Lastly, we would determine the intercept (a) as follows;

[tex]a = \bar{y} - b\bar{x}[/tex]

a = 8.4 - (0.894)8.8

a = 0.535

Therefore, the required equation is y = 0.894x + 0.535.

A. The numerator of the expression simplifies to for all​ x, so the limits are equal.
B. The limits and equal the same number when evaluated using direct substitution.
C. Since whenever x​, it follows that the two expressions evaluate to the same number as x approaches .
D. Since each limit approaches ​, it follows that the limits are equal.

Answers

Answer:

B. The limits Lim x-->7 (x²-9x+14)/x-7  and  lim x--> 7 (x-2) equals the same number when evaluated using direct substitution. The limit of both functions is 5

Step-by-step explanation:

Find the complete question in the attachment.

Given the limit of the functions

Lim x-->7 (x²-9x+14)/x-7

To solve this, we will need to factorize the quadratic function at the numerator first.

x²-9x+14

= x²-2x-7x+14

= x(x-2)-7(x-2)

= (x-7)(x-2)

The expression therefore becomes:

= lim x-->7 (x-7)(x-2)/x-7

= lim x-->7 (x-2)

Now substitute the value of x into the simplified function

lim x-->7 (x-2) = 7-2

lim x-->7 (x-2) = 5

Hence Lim x-->7 (x²-9x+14)/x-7 = 5

From the calculation above, it can be seen that Lim x-->7 (x²-9x+14)/x-7 = lim x--> 7 (x-2) = 5

Hence the correct answer based on the explanation above is B.

The limits Lim x-->7 (x²-9x+14)/x-7  and  lim x--> 7 (x-2) equals the same number when evaluated using direct substitution.

Answer:

Hey there,

Let the angle ABC = x

Let the angle CBE = y

Let the angle EBD = z

We want to find x.

So, we are given the following:

x+y+z=85

z=21

And y=z

therefore, both y and z must equal 21.

21+21=42

85-42=43.
