The solution of simultaneous equations 5x-3y=8 and 3x+Y=2 is (1,-1)

A linear equation is an equation in which each term has at max one degree. Linear equations in variables x and y can be written in the form y=mx+c

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

The given equations are:

5x-3y=8  ------(1)

3x+y=2   -------(2)

By solving the equations we get the points

Multiply equation(1) by 3 and equation (2) by 5 then we get

15x-9y=24

15x+5y=10

By solving the above equations we get x and y values.

-14y=14

y=-1

substitute y=-1 in equation(1) we get x value.

5x-3(-1)=8

Answer:

D. x=2, -2

Step-by-step explanation:

I think you're asking for the correct answer to the problem because all of the values for x won't work for the equation.

So all we have to do is simplify the equation to isolate x.

[tex]2x^2-8=0[/tex] (original problem)

[tex]2x^2=8[/tex] (add 8 to both sides)

[tex]x^2=4[/tex] (divide both sides by 2)

[tex]x=2, x=-2[/tex] (find the square root of both sides)

Note that x = ±2 and note just 2 because both [tex]2^2[/tex] and [tex](-2)^2[/tex] [tex]=4[/tex].

Out of 82, 58 tickets were sold to students and 24 tickets were sold to the adults for the musical.

How to solve an equation for x?

To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.

According to the given question:

Let the tickets sold to students be x.

Since total number of sold tickets are 82, the number of tickets sold to families will be 82 - x (that is 82 minus number of tickets sold to students)

Cost for one ticket for students is $3

So, the amount after selling tickets to students = 3x ---- 1)

Similarly, cost of one ticket for an adult is $5

Hence the amount after selling tickets to adults = 5(82 - x) ----- 2)

Total sales from selling tickets is $294

From equation 1) and 2)

3x + 5(82 - x) = 294

Solving for the value of x

3x + 410 - 5x = 294

2x = 410 - 294

2x = 116

x = 58

Therefore, out of 82, 58 tickets were sold to students and (82 - 58) = 24 tickets were sold to adults.

After covering a distance of 160-mile rental cost of both company will become same.

Mathematical expressions with the symbols >,<, ≥ and ≤  are known as inequality. Finding a range, or ranges within ranges, of values that an unknown x can have while still satisfying the inequality is referred to as "solving" an inequality. Inequalities are resolved using graphs and algebra. It is imperative that you practice the techniques described here a lot so they become second nature if you want to master them.

An inequality still exists if the same amount is added to both sides. The inequality still holds true if the same amount is subtracted from each side. An inequality still holds true if both sides are multiplied or divided by the same positive value. However, if both sides of an inequality are multiplied or divided by a negative value, the inequality is no longer valid. In actuality, the inequity is turned around.

Solving according to ques,

Let us represent distance covered be X miles.

$100+($0.30) X = $20 + ($0.80) X

subtracting $20 and ($0.30) X from both sides, we get

A quadratic inequality of the form

y>a[tex]x^{2}[/tex]+bx+c

(or substitute <,≥ or ≤ for > ) represents a region of the plane bounded by a parabola .

A quadratic inequality of the form

y>a[tex]x^{2}[/tex]+bx+c

(or substitute <,≥ or ≤ for > ) represents a region of the plane bounded by a parabola .

To graph a quadratic inequality, start by graphing the parabola. Then fill in the region either above or below it, depending on the inequality.

If the inequality symbol is ≤ or ≥ , then the region includes the parabola, so it should be graphed with a solid line.

Otherwise, if the inequality symbol is < or > , the parabola should be drawn with a dotted line to indicate that the region does not include its boundary.

Example:

Graph the quadratic inequality.

y≤[tex]x^{2}[/tex]−x−12

The related equation is:

y=[tex]x^{2}[/tex]−x−12

First we notice that a , the coefficient of the x2 term, is equal to 1 . Since a is positive, the parabola points upward.

The right side can be factored as:

y=(x+3)(x−4)

So the parabola has x -intercepts at −3 and 4 . The vertex must lie midway between these, so the x -coordinate of the vertex is 0.5 .

Plugging in this x -value, we get:

y=(0.5+3)(0.5−4)

y=(3.5)(−3.5)

y=−12.25

So, the vertex is at (0.5,−12.25) .

We now have enough information to graph the parabola. Remember to graph it with a solid line, since the inequality is "less than or equal to".

f(x)= √(x-a) +b

Step-by-step explanation:

parent function is y=√x. This has a domain and range of [0, ∞). The question asks what function transformations will move the domain to [a, ∞) and the range to [b, ∞).

Function transformations

To move the domain from [0, ∞) to [a, ∞) requires the function be translated 'a' units to the right. That transformation is accomplished by replacing x with (x-a) in the function definition.

To move the range from [0, ∞) to [b, ∞) requires the function be translated upward by 'b' units. This is accomplished by adding 'b' to every function value.

The net effect of these transformations is ...

  f(x) = √x   ⇒   f(x) = √(x -a) +b

Answer:

Step-by-step explanation:

You want to know the number of cups needed to contain 7/8 pitcher of water when each cup holds 3/16 pitcher.

The number of cups can be found by dividing the water quantity by the amount each cup holds:

  (7/8 pitcher)/(3/16 pitcher/cup) = 14/3 cups = 4 2/3 cups

Eve needs at least 5 cups to hold the amount of water in the bottle.

__

Additional comment

If every cup is filled to capacity, then the 5th cup will be 2/3 full. The number of cups can be any number greater than or equal to 5.

If you want, you can write an inequality relating the capacity of the cups to the amount of water:

  n(3/16) ≥ 7/8

  n ≥ 4 2/3 . . . . . . . . . where n is a counting number

  n ∈ {5, 6, 7, ...}

This more clearly shows that the number is not restricted to 5.

The required function obtained after solving f(g(x)) will be equal to 15x³ + 16. Hence, option C is correct.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

Now, find the function f(g(x)).

f(g(x)) = f(√5x³),                     [g(x) = √5x³]

f(g(x)) = 3( √5x³)² + 16           [f(x) = 3x² + 16]

Negative infinity is an abstract concept used to describe a value that is lower than any other real number. It is not a direction, but rather an idea of an unlimited amount of negative numbers. Although it does not have a physical direction, it can be thought of as a direction that is always negative and decreasing without bound. This concept is often used in mathematics to compare values and calculate limits. For example, when graphing a function, negative infinity is often used as the lower bound on the x-axis. Negative infinity is also used to describe the behavior of certain equations when a variable approaches a certain value or when a denominator approaches zero. In these cases, the equation would approach negative infinity.
