Solve the following simultaneous equations 2x+5y=0 and 3x-4y=23
Answers
Answer:
x = 5, y = -2
Step-by-step explanation:
2x + 5y = 0 --- Equation 1
Equation 1×3: 6x + 15y = 0 --- Equation 2
3x - 4y = 23 --- Equation 3
Equation 3×2: 6x - 8y = 46 --- Equation 3
We will be eliminating 6x from Equation 2.
Equation 3-2: 6x - 8y - 6x - 15y = 46-0
-23y = 46
y = 46 ÷ -23
y = -2
Substitute y = -2 into Equation 1:
2x + 5y = 0
2x + 5(-2) = 0
2x + (-10) = 0
2x - 10 = 0
2x = 10
x = 10 ÷ 2
x = 5

The sum of a three digit number and a one digit number is 731 the product of the number is 2908 what are the numbers
Answers
The one digit number is 4 and three digit number is 727.
Let us consider the one digit number be a and three digit number be b. Given that their sum is equal to 731.
a + b = 731 : equation 1
Also, their product is equal to 2908.
a × b = 2908 : equation 2
Now, from equation 1, the value of b is
b = 731 - a : equation 3
Putting the value of b in equation 2, we get
a (731 - a) = 2908
731a - a² = 2908
a² - 731a + 2908 = a
Using middle term splitting, the equation can be written as
a² - 727a - 4a + 2908 = 0
a(a - 727) - 4(a - 727) = 0
a - 4 = 0 and a - 727 = 0
a = 4, 727
Now, putting the value of a in equation 3, we get
b = 731 - 4 and 731 - 727
b = 727, 4
Thus, the one digit number is 4 and three digit number is 727.

Step-by-step explanation:
Edge 2020
The experimental design used by Betty is completely randomized experimental design. Hence, option A is correct.
What is an experiment?A process used to confirm or deny a theory, as well as assess the effectiveness or possibility of something that has never been performed before, is called an investigation.
By showing what happens when a particular element is modified, experiments shed light on causation relationships. Experiments have a wide range of objectives and sizes, but always depend on a repeatable process and a logical examination of the outcomes. Additionally, there are experiments conducted in nature.
As Betty is wants to bake a perfect cookie, and she has enough batter. She is testing to bake the batter at different temperatures to see that what is the ideal temperature to make perfect cookies. So, this is completely randomized experimental design.

There are 6 stamps on the last page.
The number of stamp books is 8.The number of pages in each stamp book is 42.The number of stamps on each page is 6.The total number of stamps is 8*42*6.The total number of stamps is 2016.After the reorganization of the stamps,The number of completely filled stamp books is 4.The number of completely filled pages is 42*4 + 33.The updated number of stamps on each page is 10.The number of stamps on the last page is equal to the total number of stamps minus the number of stamps on completely filled pages.The number of stamps on the last page is 2016 - [(4*42 + 33)*10].The number of stamps on the last page is 2016 - [(168 + 33)*10].The number of stamps on the last page is 2016 - (201*10).The number of stamps on the last page is 2016 - 2010.The number of stamps on the last page is 6.To learn more about stamps, visit :

(x, y) = (0, -7) and ((28/5 , 21/5)) , as found by solving the system of linear equations.
What is a system of linear equations?
A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Given: 2x - y = 7x² + y² = 49
to find: Values of x and y.
Finding:
Solving the system of two linear equations, by deriving the value of one variable from an equation and substituting it in the other equation and solving for the two variables.
eqn1 2x - y = 7
y = 2x - 7
eqn2 x² + y² = 49O
substituting the value of y from eqn1,
we get: x² + (2x - 7)² = 49
x² + 4x² + 49 - 28x = 49
5x² -28x = 0
x ( 5x - 28) = 0
x = 0, x = 28/5
For x = 0, y = -7 (in eqn1)=>
(x, y) = (0, 7)
For x = 28/5
y = 2(28/5) - 7
= (56 - 35) / 5
= 21 / 5
(x,y) = (28/5 , 21/5)
Hence, (x, y) = (0, -7) and (28/5 , 21/5), as found by solving the system of linear equations.
