(x^2+14x)+(y^2+12y)=-60
add negative and positive 1/2 of linear coefs inside parenthaees
14/2=7, 7^2=49
12/2=6, 6^2=36
(x^2+14x+49-49)+(y^2+12x+36-36)=-60
factor perfect square
((x+7)^2-49)+((y+6)^2-36)=-60
get rid of parnthaeses
(x+7)^2-49+(y+6)^2-36=-60
(x+7)^2+(y+6)^2-85=-60
add 85 to both sides
(x+7)^2+(y+6)^2=25

The length of BC is four times the length of AB.
BC = 100 metres.
Work out the length AC.
It should be 125 as
BC=100
and it's four times the length of AB then
100/4=25
then 100+25=125

George, Charlotte and Louis share some money in the ratio 2:5:6 Louis gets £39 How much did they share?
Answer:
£84.5
Step-by-step explanation:
Given ratio = 2:5:6
Amount that Louis got from the total amount = £39
Step 1: Add the ratio together
2+5+6=13
Step 2: covert the given ratio into fraction
George ratio=2/13
Charlotte ratio=5/13
Louis ratio= 6/13
✓LET THE AMOUNT THAT WAS SHARED AMONG THEM= Y
But we know that Louis got £39, then we can compute How much did they shared using "Louiz" shrare as
Louis ratio= 6/13 × Y= £39
= 6Y/13 = 39
Cross multiply
13×39= 6Y
507= 6Y
Y= 84.5
Hence, the amount they shared was £84.5
which quotient shows the decimal placed correctly?
a. 6÷0.5=1.2

Answer:
f(x)= -2|x-3|-1
(Hi Simran! I just wanted to help you with this question though it might be wrong)
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a
-------------------------------------------------------------------------------------
The equation of the absolute value is f(x)= -2|x-3|-1

The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09

Need help finding the value of x
Answer:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
As we know that,
Sum of all angles of triangle = 180°
Given,
Angles are 2x , 3x and 50°
Now,
[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]
When plus sign goes to another side then,it become minus.
[tex] \rightarrow \: 5x = 180 - 50[/tex]
[tex] \rightarrow \: 5x = 130[/tex]
[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]
[tex] \rightarrow \: x = 26[/tex]
Hence,the value of x is 26°.

Answer:
A. 200
B. Growth
C. 118%
Step-by-step explanation:
Answer:
Initial population size=200
The function represents a growth
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 200(1.18)^t
To find initial population size we will take t = 0
P(0) = 200(1.18)^0
= 200(1)
= 200
To find that function represent growth or decay
P(1) = 200(1.18)^1
= 200(1.18)
= 236
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(236 - 200 / 200) * 100%
= 235%
