Graph the following systems of equations and determine the solution of the system .
Answer:
We can find the solution to a system of equations by graphing the equations. Let's do this with the following systems of equations:
Convert the circle to standard form.
[tex] {9x}^{2} + {9y}^{2} + 18x + 9y - 36 = 0[/tex]
Answer:
(x + 1)² + (y + 1)² = (√6)²
Step-by-step explanation:
Group the x- and y- terms together:
9x^2 + 18x + 9y^2 + 9y = 36
Factor out the coefficient 9:
x^2 + 2x + y^2 + y = 4
Complete the square of x^2 + 2x and then do the same for y^2 + 2y:
x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4
Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:
(x + 1)^2 + (y + 1)^2 - 2 = 4
Collect the constant terms on the right side:
(x + 1)^2 + (y + 1)^2 = 6
Rewrite 6 as (√6)^2:
(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²
Completing the square is done as follows: x^2 + 2x
Start with x^2 + 2x
1. Take half of the coefficient of x, which results in 2/2, or 1
2. Square this result and add it to, and subtract it from x^2 + 2x
x^2 + 2x + 1 - 1
3. Rewrite the first three terms as the square of a binomial:
x^2 + 2x + 1 - 1 = (x + 1)² - 1.
Do the same for y² + 2y.
Find the equation of the line containing the points (-2,0), (4, 18) and (5,21).

Pilar made 6 quarts of orange marmalade to store in jars. If she puts 1/4 quart of marmalade into each jar how many jars will she need
Answer: 24
Step-by-step explanation:
Given
Pilar made 6 quarts of orange marmalade
If each jar stores [tex]\frac{1}{4}\ \text{or}\ 0.25[/tex] quart of marmalade then
No of jars required to store marmalade is
[tex]\Rightarrow n=\dfrac{6}{\frac{1}{4}}=\dfrac{6\times 4}{1}=24\ \text{jars}[/tex]
Answer:
24
Step-by-step explanation:
Okay she got 6 quarts of orange marmalade and she pouring 1/4 quarts into a jar.
I will draw out the problem for you
1/4 + 1/4 +1/4 + 1/4 = 1 quart
1/4 + 1/4 +1/4 + 1/4 = 2 quart
1/4 + 1/4 +1/4 + 1/4 = 3 quart
1/4 + 1/4 +1/4 + 1/4 = 4 quart
1/4 + 1/4 +1/4 + 1/4 = 5 quart
1/4 + 1/4 +1/4 + 1/4 = 6 quart
and if u count all the 1/4 in the thing I just type, it will be 24
which of the following statements describe the system ?
Answer:
one solution
Step-by-step explanation:
here, we want to select the correct option
From the system, we have two values of y
Equating the y-values
3x + 2 = -2x - 1
What this mean is that there is only a particular point where this solution will work and as such, the system has one solution
Leo estimates that a package weighs 27 pounds. The postal clerk weighs it and finds it weighs 20 pounds. What is the percent error in Leo's estimate?
Answer: 35%
Step-by-step explanation:
Given
Weight measured by Leo [tex]W_1=27\ pounds[/tex]
Weight measured by the clerk [tex]W_2=20\ pounds[/tex]
Percentage error is
[tex]\Rightarrow \%\ \text{error}=\dfrac{\text{False value}-\text{Correct value}}{\text{Correct value}}\times 100[/tex]
Putting values
[tex]\Rightarrow \%\ \text{error}=\dfrac{27-20}{20}\times 100=35\%[/tex]

Kylie invested $290 in an account paying an interest rate of 2.5% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $390?
Answer:
t= 11.9
Step-by-step explanation:
Compounded Continuously:
A=Pe^{rt}
A=Pe
rt
A=390\hspace{35px}P=290\hspace{35px}r=0.025
A=390P=290r=0.025
Given values
390=
390=
\,\,290e^{0.025t}
290e
0.025t
Plug in
\frac{390}{290}=

\ln\left(1.3448276\right)=
ln(1.3448276)=

)
Take the natural log of both sides

0.025t
ln cancels the e
