The number of weeks it will take them to have saved thesame amount is 8 weeks
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time.
if x represents the the number of weeks for saving and y represents the equal saved amount, then
42+16x = y equation 1
-70+ 30x = y equation 2
subtract equation 1 from 2
-70-42+16x- 30x= 0
-112+14x= 0
collect like terms
-112=-14x
divide both sides by 14
x= -112/-14
x= 8weeks
therefore it will take them 8 weeks to have equal savings

Five times a number plus four times a second number is 20. Four times
the first number added by two times the second number is 16. Write the
system of equations for this situation. *
Answer:
first number is 4
second number is 0
Step-by-step explanation:
y = 1st number
x = 2nd number
system of equations:
5y + 4x = 20
4y + 2x = 16
I multiplied the second equation by -2 to eliminate the 'x-values'
-2(4y + 2x = 16) = -8y - 4x = -32
now add to 1st equation: 5y + 4x = 20
-3y = -12
y = 4
solve for 'x':
5(4) + 4x = 20
20 + 4x = 20
4x = 0
x = 0

The function ƒ(x) = x−−√3 is translated 3 units in the negative y-direction and 8 units in the negative x- direction. Select the correct equation for the resulting function.
The final function after transformations, is \(f(x +8) = \sqrt[3]{x+8} - 3\)
The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. The modification of algebraic equations is a typical form of algebraic problems. Sometimes graphs are translated, or moved about the xy-plane; sometimes they are stretched, rotated, inverted, or a combination of these transformations.
Now, there are 2 different transformations applied to the function here.
First Transformation:
\(f(x) = \sqrt[3]{x}\) is translated 3 units in the negative y direction.
After transformation, the function is \(f(x) = \sqrt[3]{x} - 3\).
Second Transformation:
The function \(f(x) = \sqrt[3]{x} - 3\) is translated 8 units in the negative x direction.
After transformation, the function is \(f(x +8) = \sqrt[3]{x+8} - 3\).
Therefore, the final function, after transformations, is \(f(x +8) = \sqrt[3]{x+8} - 3\).

How to find the orthocenter of a triangle - example triangle
O Point M is at (1, 3)
O Point R is at (3, 9)
O Point E is at (10, 2)
A triangle contains three vertices, three sides, and three altitudes. The location where these three sides intersect is known as the orthocenter.
To find orthocenter follow the below steps:Every triangle has a different position for the orthocenter; for example, an equilateral triangle has the same orthocenter, circumcenter, incenter, and centroid, but other triangles will have a different position.
At Point M is at (1, 3) : The orthocenter is located inside an acute-angled triangle in this scenario.
At Point R is at (3, 9) : The orthocenter is located outside the triangle in the case of an obtuse-angled triangle.
At Point E is at (10, 2) : The orthocenter of a right-angled triangle is located at the right angle's apex.
A triangle is a basic three-sided polygon with three vertices. The "orthocenter of a triangle" is the intersection of a triangle's three altitudes, and it is typically depicted by the letter "H." A line segment drawn perpendicularly from each vertex to the opposite side of a triangle's opposing side is the triangle's height.

A car loan worth 800,000 pesos is to be settled by making equal monthly payments at 7% interest compounded monthly for 5 years. How much is the monthly payment? How much is the outstanding balance after 2 years?
The monthly payment for the car loan is approximately 16,216.38 pesos. The outstanding balance after 2 years is approximately 650,577.85 pesos.
To find the monthly payment for the car loan, we can use the formula for the monthly payment on a loan:
P = (r * PV) / (1 - (1 + r)^(-n))
Where:
P is the monthly payment
r is the monthly interest rate
PV is the loan amount (present value)
n is the total number of payments
In this case, the loan amount PV is 800,000 pesos, the monthly interest rate r is 7% / 12 (since the interest is compounded monthly), and the total number of payments n is 5 years * 12 months/year = 60 months.
Substituting these values into the formula, we have:
P = (0.07/12 * 800,000) / (1 - (1 + 0.07/12)^(-60))
Calculating this expression, we find that P ≈ 16,216.38 pesos.
So, the monthly payment for the car loan is approximately 16,216.38 pesos.
To find the outstanding balance after 2 years, we need to calculate the remaining balance after making monthly payments for 2 years. We can use the formula for the remaining balance on a loan:
Remaining Balance = PV * (1 + r)^n - P * ((1 + r)^n - 1) / r
Where:
PV is the loan amount (present value)
r is the monthly interest rate
n is the number of payments made
Substituting the given values into the formula, we have:
Remaining Balance = 800,000 * (1 + 0.07/12)^24 - 16,216.38 * ((1 + 0.07/12)^24 - 1) / (0.07/12)
Calculating this expression, we find that the outstanding balance after 2 years is approximately 650,577.85 pesos.
So, the outstanding balance after 2 years is approximately 650,577.85 pesos.

17. sketch each angle. then find its reference angle. show your calculations. a. 13pi/8
The reference angle for 138 is 58.
Let's first sketch the angle and then find its reference angle using the terms you mentioned.
Step 1: Sketch the angle 13π/8
To sketch the angle, first, we need to determine its position on the coordinate plane. Since 13/8 is greater than (or 8/8), it's located in the third quadrant. As a full circle is 2 (or 16/8), we can determine the angle measured counterclockwise from the positive x-axis as:
Angle = 13π/8
Step 2: Find the reference angle
A reference angle is an acute angle formed between the terminal side of the angle and the x-axis. In the third quadrant, the reference angle is calculated as:
Reference Angle = Angle - π
Now we substitute the values:
Reference Angle = 13π/8 - 8π/8 = 5π/8
So, the reference angle for 138 is 58.

Consider the nonlinear ordinary differential equation dx/dt =x^{2}-x-6. Find all equilibrium points and determine their stability.
The equilibrium points of the given nonlinear ordinary differential equation dx/dt = x^2 - x - 6 are x = -2 and x = 3.
To find the equilibrium points of the given nonlinear ordinary differential equation, we set dx/dt equal to zero and solve for x. In this case, we have:
x^2 - x - 6 = 0
Factoring the quadratic equation, we get:
(x - 3)(x + 2) = 0
Setting each factor equal to zero, we find two equilibrium points:
x - 3 = 0 --> x = 3
x + 2 = 0 --> x = -2
So, the equilibrium points are x = -2 and x = 3.
To determine the stability of these equilibrium points, we can analyze the behavior of the system near each point. Stability is determined by the behavior of solutions to the differential equation when perturbed from the equilibrium points.
For the equilibrium point x = -2, we can substitute this value into the original equation:
dx/dt = (-2)^2 - (-2) - 6 = 4 + 2 - 6 = 0
The derivative is zero, indicating that the system is at rest at x = -2. To analyze stability, we can consider the behavior of nearby solutions. If the solutions tend to move away from x = -2, the equilibrium point is unstable. Conversely, if the solutions tend to move towards x = -2, the equilibrium point is stable.
For the equilibrium point x = 3, we substitute this value into the original equation:
dx/dt = 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Similar to the previous case, the system is at rest at x = 3. To determine stability, we analyze the behavior of nearby solutions. If the solutions move away from x = 3, the equilibrium point is unstable. If the solutions move towards x = 3, the equilibrium point is stable.
In conclusion, the equilibrium points of the given nonlinear ordinary differential equation are x = -2 and x = 3. The stability of x = -2 and x = 3 can be determined by analyzing the behavior of nearby solutions.

Answer:
There are two ways to find the area of this triangle. One way is to do 19.4 * h / 2 and the other way is to do 17 * 9.4 / 2. Since these are equal we can write:
(19.4h) / 2 = (17 * 9.4) / 2
19.4h = 17 * 9.4 (Multiply the equation by 2 to get rid of the denominators)
h = 17 * 9.4 / 19.4 (Divide by 19.4)
