Answer:
(x - 9)² + (y - 7)² = 262
Step-by-step explanation:
x² + y² - 18x - 14y - 132 = 0
Rearranging the equation:
y² - 14y + x² - 18x - 132 = 0
add 132 to both sides:
y² -14y + x² - 18x - 132 + 132 = 0 + 132
y² -14y + x² - 18x = 132
add to both sides the square of half of the coefficient of y (i.e (14/2)² = 49)
y² -14y + 49 + x² - 18x = 132 + 49
add to both sides the square of half of the coefficient of x (i.e (18/2)² = 81)
y² -14y + 49 + x² - 18x + 81 = 132 + 49 + 81
y² -14y + 49 - x² - 18x - 81 = 262
y² - 7y - 7y + 49 + x² - 9x - 9x - 81 = 262
y(y - 7) - 7(y - 7) + x (x - 9) -9(x - 9) = 262
(y - 7)(y - 7) + (x - 9)(x - 9) = 262
(y - 7)²+ (x - 9)² = 262
(x - 9)² + (y - 7)² = 262

Answer:
three hundred fourteen thousandths3 x (1/10) + 14 x (1/1000)Step-by-step explanation:
In written form:
three hundred fourteen thousandths
In standard form:
0.314
In expanded form:
3 x (1/10) + 14 x (1/1000)
3 x (1/10) = .3
14 x (1/1000) = .014
.3 + .014 = .314
Therefore, these are the two correct answer choices.

Suppose that the mean number of chocolate chips in 30 cookies is 19 chocolate chips. Explain what this means.
Answer: It means that there are 570 chocolate chips in all the 30 cookies
Step-by-step explanation:
The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.
Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:
= (30 × 19) = 570 chocolate chips in the cookies.

Answer:
Given below
Step-by-step explanation:
M is Mikey and B is Betty in,
Current ages:
M= x
B= 3x (cuz she is 3 times older)
After 5 years
M= x+5
B= 3x+5 (5 years added to present age)
It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))
So,
3x+5 = 2(x+5)
3x+5 = 2x+10
3x -2x = 10-5
x = 5
Therefore,
The current ages are
Betty : 3x = 3*5 = 15
Mikey: 5 (x)
You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

Jose sells portraits for $300 each. Each portrait costs him $150 in supplies and he spends $2,100 per year on fixed costs. Last year Jose sold 140 portraits. He believes that he made more than $20,000 in profit. Is this true? WILL GIVE BRAINLIEST PLEASE HELP! a) Write an expression to represent José's yearly profit. Use x to represent the number of portraits sold. b) Simplify the expression from Part I. Then, evaluate the expression for the 140 portraits José sold last year to determine if he actually made $20,000 dollars in profit. Write your answer as a complete sentence.
Answer:
a) y=(300-150)x-2100
b) y=150x-2100
c) y=150(140)-2100
y=18900
Jose was wrong. He did not make 20000 dollars last year.
Answer:
A: ((300-150) * 140) - 2100
B: 21000-2100= $18,900 profit.
Jose made 18,900 dollars worth of profit. He did not make $20,000 worth of profit.
Rename 3/4 and 9/10 using the least common denominator.
Answer:
15/20 and 18/20
Step-by-step explanation:
Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10
multiples of 4: 4, 8, 12, 16, 20
multiples of 10: 10, 20
Least common denominator = 20
Rewrite fractions: 15/20 and 18/20
3/4 and 9/10 using the least common denominator is 15/20 and 18/20.
What is LCM?LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.
Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.
∴ (3×5)/(4×5) and (9×2)/(10×2). (we have to multiply same constant to the
fraction to retain it's original value).
So, 3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

Simplify the expression completely. 7b+3(4b−2)+6÷3
Answer:
19b-4
Step-by-step explanation:
7b+3(4b-2)+6÷3
Bracket comes first so we distribute 3 over the terms in the bracket
= 7b + 12b -6 +6 ÷ 3
First we solve division
= 7b + 12b -6 +6 ÷ 3
= 7b + 12b -6 +2
= (7b+12b)+(-6+2)
= 19b -4
This can't be simplified further as it can't be solved anymore
Answer:
19b - 4
Step-by-step explanation:
Distribute the 3 to (4b - 2), like so:
3(4b - 2)
12b - 6
→ 7b + 12b - 6 +6 ÷ 3
Add like terms:
→19b - 6 + 6 ÷ 3
Following PEMDAS, you divide 6 by 3 first:
→19b - 6 + 2
Add like terms:
→19b - 4
Answer only. What is the greatest possible sum of the digits of a six-digit number that is a multiple of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11?
Answer: 36
The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.
A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.
The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.
We now look at the next biggest multiple of 9, 9 × 4
= 36.
The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.

Answer:
x = 18
Step-by-step explanation:
Given
[tex]\frac{3x}{5}[/tex] + 1 = [tex]\frac{4x}{15}[/tex] + 7 ( subtract 1 from both sides )
[tex]\frac{3x}{5}[/tex] = [tex]\frac{4x}{15}[/tex] + 6
Multiply through by 15 to clear the fractions
9x = 4x + 90 ( subtract 4x from both sides )

Mike can plow a field in 12 hours and his brother Phil can plow it in 15 hours. How long will it take them to plow it if they use two plows and work together?
Answer:
6.66 hours, that is, 6 hours and 40 minutes.
Step-by-step explanation:
If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.
If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.
So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:
(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66
So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.
