According to Maths, in order to solve a system of linear equations by graphing, we must first graph both equations in the same coordinate plane and then locate the intersection of the two lines.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."

According to the discussion above, a system of equations is a collection of equations that aim to find a common solution for all of the variables. An illustration of a system of equations is the set of equations below.

2x - y = 12

x - 2y = 48

Finding the values of the variables employed in a system of equations entails solving the set of equations. While keeping the equations balanced on both sides, we compute the values of the unknown variables. Finding the value of the variable that makes the condition of all the given equations true is the primary goal when solving an equation system. A given system of equations may have a variety of solutions,

There are numerous ways to solve any set of equations. We require at least two equations in order to solve a system of two-variable equations. Similar to this, we will need at least 3 equations to solve a system of 3 equations. Let's examine three approaches to solving a set of equations, presuming that they are linear equations in two variables.

Answer:

a=7300, b=1.0108.

L(t) = 7300(1.0108)^t

Step-by-step explanation:

First, we can see that L(t) = 7300(1.012)^(4t) can be rewritten as L(t) = 7300e^(4tln(1.012))

Using the properties of logarithms, we can simplify this to L(t) = 7300e^(4t(ln(1.012))

Now, we can see that the function L(t) is in the form L(t) = ab^t, where a = 7300 and b = e^(ln(1.012))

Therefore, we can write the equivalent function as L(t) = 7300e^(0.048t)

The final values rounded to 4 decimal places are a=7300, b=1.0108.

Answer:8534.46

Step-by-step explanation:

The depreciated value of the bike after 12 years is $8534.46

Depreciated value is the minimum amount that an asset is worth after depreciation.

Given that, the value of a motorcycle is depreciating by 2.8% each year, the bike was purchased for $12,000,

We know that, the depreciation value is given by,

A = P(1-r)ⁿ

A = final amount

P = initial amount

r = rate

n = years or time

Therefore,

A = 12000(1-0.028)¹²

A = 12000(0.972)¹²

A = 8534.46

Hence, the depreciated value of the bike after 12 years is $8534.46

Step-by-step explanation:

Answer:

The function g(x) = √(x - 3) is defined for all real numbers x such that x - 3 ≥ 0, since the square root of a non-negative number is a real number.

Solving for x, we have:

x - 3 ≥ 0

x ≥ 3

Therefore, the domain of the function is D: [3, ∞).

Since the square root of a non-negative number is always non-negative, the range of the function is R: [0, ∞).

Therefore, the correct answer is: A. D: [3, ∞) and R: [0, ∞).

The final graph is given below in the image.

The equation is [tex]y = -\frac{3}{4}x - 2[/tex]

The graph of a linear equation in two variables is a line (that's why they call it linear).

If you know an equation is linear, you can graph it by finding any two solutions

(x1,y1) and (x2,y2)

plotting these two points, and drawing the line connecting them.

You can find two solutions, corresponding to the x-intercepts and y-intercepts of the graph, by setting first x=0 and then y=0.

To graph the line [tex]y = -\frac{3}{4}x - 2[/tex] we are going to take advantage of the fact that its y-intercept is -2 when x = 0, so our first point is (0,-2). To find our second point, we are going to find the x-intercept; to do it, we are going to set y = 0 and solve for x:

[tex]y = -\frac{3}{4}x - 2\\0 = -\frac{3}{4}x - 2\\2 = -\frac{3}{4}x \\x = -\frac{8}{3}[/tex]

Now, we have our second point (0, -8/3), we just need to join the 2 points with a straight line.

The graph of the function f(x) = −15|x−40|+8 will be a piecewise linear function.

Graph explain: What is it?

A graph is defined as a mathematical structure that connects a collection of points to express a specific function. A pairwise relationship between the objects is established using it. The edges that connect the graph's vertices (also known as nodes) are its vertices (lines).

It will be a V-shape, with the vertex at x = 40 and y = 8.

On the left side of the vertex, the function will be decreasing, representing Tyra moving away from home.

On the right side of the vertex, the function will be increasing, representing Tyra moving towards home.

The vertex at x = 40 and y = 8 represents the point in time where Tyra reaches her furthest distance from home (8 miles) and then begins to head back towards home.

Key features of the graph in the context of the situation:

The vertex at x = 40 and y = 8 represents the point in time where Tyra reaches her furthest distance from home (8 miles) and then begins to head back towards home.

The left side of the vertex represents the time period when Tyra is moving away from home, and the right side represents the time period when Tyra is moving towards home.

The slope of the graph on the left side of the vertex is negative, indicating that Tyra is moving away from home at a decreasing rate, while the slope of the graph on the right side of the vertex is positive, indicating that Tyra is moving towards home at an increasing rate.

The y-intercept is at 8, which means Tyra starts 8 miles away from home.

The graph is symmetric about the y-axis because for every time x on the left side of the vertex, there is a corresponding time on the right side of the vertex.

The graph is not a function because for every x value, there are two y values, one for when Tyra is moving away from home and one for when Tyra is moving towards home.

If the two lines crossed are parallel, the alternate angles are equal. It is proven that the sum of the three angles of a triangle is equal to 180 degrees.

We have to prove that ∠A + ∠B + ∠C is equal to 180 degrees.

The measure of A = ∠1

B = ∠2

C = ∠3

Given, l || BC

We know that the alternate angles are equal in parallel lines.

∠2 = ∠4 -------------- (1)

∠3 = ∠5 -------------- (2)

Adding (1) and (2),

∠2 + ∠3 = ∠4 + ∠5

By adding ∠1 on both sides,

∠1 + ∠2 + ∠3 = ∠4 + ∠5 + ∠1

From the figure,

The sum of the angles at a point on a line is equal to 180 degrees.

∠4 + ∠1 + ∠5 = 180°

So, ∠1 + ∠2 + ∠3 = 180°

Therefore, ∠A + ∠B + ∠C = 180°

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{5\sqrt{3} }{y}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

y × [tex]\sqrt{3}[/tex] = 10[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

y = 10

-----------------------------------

using Pythagoras' identity in the right triangle

x² + (5[tex]\sqrt{3}[/tex] )² = y² = 10²

x² + 75 = 100 ( subtract 75 from both sides )

x² = 25 ( take square root of both sides )
