8 -2=6
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.

helpppp someone !!! It’s due midnight tonight .
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.

how does the quotient compare to the dividend when the divisor is less than 1
Answer:
Greater provided the divisor is positive.
It would be more accurate and clearer to say that when dividing a number which is greater than zero by a number between 0 and 1, then the quotient is greater than the dividend.
If the divisor is negative and the dividend is positive, then the quotient is negative (and so less than the dividend).
how can you find the domain and range in a discrete graph ?
The way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
what does it mean when the graph is flat ?
Use the given domain to find the range of function:

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.

Cynthia Besch wants to buy a rug for a room that is 20 ft wide and 26 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 432 square feet of carpeting. What dimensions should the rug have?
Answer:
18 ft. wide by 24 ft. long
Step-by-step explanation:
this would leave a uniform strip of 2 ft around the rug and stay in her price range for 432 square feet of carpeting.
and 18 times 24 = 432 square feet

Choose the correct answer below.
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.
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.

Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Answer:
D. y = -³/2x - 1
Step-by-step explanation:
Given that a line has a slope (m) of -³/2, and a y-intercept of -1, an equation of this line in the slope intercept form is given as y = mx + b.
Where,
m = slope of the line = -³/2
b = y-intercept of the line = -1.
Substitute m = -³/2, and b = -1 into y = mx + b to get the equation of the line in slope-intercept form.
Thus, we would have:
y = -³/2x + (-1)
y = -³/2x - 1
To get to the dance competition finals, a dancer must average at least 8.5 points on their 4 preliminary dances. The scores for Jodi’s first 3 dances were: 8.9 points, 7.1 points, and 9.2 points.
What is the lowest score that Jodi can get on the last dance and still make the finals?
Show all your work AND justify your steps.
Answer:
She must score an 8.8 or higher
Step-by-step explanation:
The average is the sum of the number divided by the number of numbers
Let x be the score on the 4th dance
The average is
( 8.9+7.1+ 9.2+x)/4
This must be at least 8.5
( 8.9+7.1+ 9.2+x)/4≥ 8.5
Multiply by 4
( 8.9+7.1+ 9.2+x)/4*4≥ 8.5*4
( 8.9+7.1+ 9.2+x)≥ 34
Combine like terms
( 25.2+x)≥ 34
Subtract 25.2 from each side
( 25.2-25.2+x)≥ 34-25.2
x≥ 8.8
She must score an 8.8 or higher
