Answer:
{ (-441/23, 433/23) }
Step-by-step explanation:
The "cross-multiplication method" is usually shown as follows:
1. rewrite the equations in general form: ax +by +c = 0
2. write the coefficients in two row in the order b, c, a, b.
3. form three products, each being the number in the first row times the number to its right in the second row. That is, b1·c2, c1·a2, a1·b2
4. form three more products, each being the number in the second row times the number to its right in the first row. That is, b2·c1, c2·a1, a2·b1
5. form three differences, subtracting the products of step 4 from those of step 3. Call these differences d1, d2, d3. (For example, d1=b1c2-b2c1.)
6. The values of x and y satisfy the equations ...
x/d1 = y/d2 = 1/d3
which is to say, ...
x = d1/d3, and y = d2/d3
_____
For your equations, we can rewrite them as ...
11x +12y -15 = 012x +11y +23 = 0Then our rows of coefficients are ...
[tex]\begin{array}{cccc}12&-15&11&12\\11&23&12&11\end{array}[/tex]
And our differences are ...
d1 = 12(23) -11(-15) = 441
d2 = -15(12) -23(11) = -433
d3 = 11(11) -12(12) = -23
The relations between x and y are ...
x/441 = y/-433 = 1/-23
so, x = -441/23 and y = 433/23
The solution set is one ordered pair: { (-441/23, 433/23) }.

Additional comments
The final solution is identical to the formula arrived at using Cramer's Rule. Calling this the "cross-multiplication method" avoids any discussion of matrices and determinants.
11. What is the difference between a theorem and a postulate?
Answer:
A postulate is a statement that is assumed to be true based on basic geometric principles. A theorem is a mathematical statement that can and must be proven to be true.
Step-by-step explanation:
www.ck12.org
Answer:
A thorem is true and can be proven true vs a postulate is guessed true without any evidence.
Step-by-step explanation:
A theorem is a group of statements that are used to prove something else, whereas a postulate is a statement that is not proved but is true through reasoning.
Write equation of the circle with center c(-1, 5) and radius 3
Answer:
(x+1)^2 + (y-5)^2 = 9
Step-by-step explanation:
center = (h, k)
(x-h)^2 + (y-k)^2 = r^2
(x-(-1))^2 + (y-5)^2 = (3)^2
(x+1)^2 + (y-5)^2 = 9

At the park, a statue stands on a marble base. The statue and marble base have a total height of 59.4 inches. The height of the marble base is 16.09 centimeters. Given that 1 inch is equal to 2.54 centimeters, what is the height of the statue?
Answer:
134.786 centimeters
Step-by-step explanation:
First you need to convert inches to cm by doing 59.4x2.54=150.876 then you subtract 16.09 from that. Your answer would be 134.786 centimeters

Statment: Find the measure of the angle indicated by 19x+5
Options: 130
50
80
100
Answer:
100
Step-by-step explanation:
These two angles are corresponding which means they add up to 180.
so... 19x+5+(16x)=180
If you simplify...
35x+5=180
Then solve for x...
35x=175
x=5
Then take that 5 and fill it into 19x+5...
19(5)+5
95+5=100
b. His sister, Janine, used a light bulb that consumed 6080 joules of energy in 190
seconds. What is the unit rate at which this light bulb used energy?
Answer: 32 joules per second. That is equivalent to 32 Watts
Step-by-step explanation:
Divide units by time . 6080/190 = 32
1 joule per second is one watt.

Solve the system of equations using substitution.
- 4x + 4y= 8
y= -2x – 10
-
O (4, -18)
O (12, -34)
o(-4,-2)
O (-2,-6)
Answer:
(- 4, - 2 )
Step-by-step explanation:
Given the 2 equations
- 4x + 4y = 8 → (1)
y = - 2x - 10 → (2)
Substitute y = - 2x - 10 into (1)
- 4x + 4(- 2x - 10) = 8 ← distribute and simplify left side
- 4x - 8x - 40 = 8
- 12x - 40 = 8 ( add 40 to both sides )
- 12x = 48 ( divide both sides by - 12 )
x = - 4
Substitute x = - 4 into (2) for corresponding value of y
y = - 2(- 4) - 10 = 8 - 10 = - 2
Solution is (- 4, - 2 )

Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of -36.14 degrees Celsius and a boiling point of 324.84 degrees Celsius . What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state?
Answer:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.
Step-by-step explanation:
Matter generally exists in either a solid, liquid or gaseous form. With each phase having a certain range of temperature.
Temperature scale of a given substance can be either in Celsius, Fahrenheit or Kelvin. And conversion from one scale to another can be achieved. Example, Celsius scale can be converted to Fahrenheit by:
F = [tex]\frac{9}{5}[/tex] θ + 32
where: F is the equivalent temperature in Fahrenheit, θ is the value of temperature in degree Celsius.
Given that: melting point of the substance = [tex]-36.14^{o}[/tex]C
⇒ F = [tex]\frac{9}{5}[/tex] x [tex]-36.14^{o}[/tex] + 32
= [tex]-33.052^{o}[/tex]F
The boiling point = [tex]324.84^{o}[/tex]C
F = [tex]\frac{9}{5}[/tex] x [tex]324.84^{o}[/tex] + 32
= [tex]616.712^{o}[/tex]F
The melting point of the substance is [tex]-33.052^{o}[/tex]F, and boiling point is [tex]616.712^{o}[/tex]F.
Therefore, the range of temperatures for which the substance is not in a liquid state are:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.

Answer:
D.
Step-by-step explanation:
solve each of these equations.
2(x+5)=3x+1
Answer:
x = 9
Step-by-step explanation:
2(x + 5) = 3x + 1
open the parenthesis
2x + 10 = 3x + 1
subtract 2x from both sides of the equation
2x - 2x + 10 = 3x - 2x + 1
10 = x + 1
subtract 1 from both sides of the equation
9 = x
Answer:
Step-by-step explanation:
Substitute
2x+10=3x+1
Subtract 3x to other side
-x+10=1
Subtract 10
-x=-9
divide -1 both sides
x= 9

You'll need to learn the formula for the circumference of a circle. If the radius is r, the circumference C is C = 2πr. It appears that your teacher is using pi for the exact circumference and 3.14 for the approximate circumference.
The radius of the first circle is 5 in. Thus, the exact circumference is
C = 2πr = 2π(5 in) = 10π in, and the approximate circumference is
C = 2(3.14)(5 in) = 31.4 in
