Answer:

  (x, y) = (4 7/9, 1 2/3)

Step-by-step explanation:

You want to solve this system of equations using the elimination method.

First of all, take a look at the coefficients of the variables:

  x: 3 and 3. Subtracting one from the other will eliminate x

  y: 4 and -2. Adding twice the second to the first will eliminate y.

The easiest elimination is accomplished by subtracting the second equation from the first:

  (3x +4y) -(3x -2y) = (21) -(11)

  6y = 10 . . . . . . . . . . simplify

  y = 10/6 = 5/3 = 1 2/3 . . . . divide by the coefficient of y

Substitute for y to find x.

  3x +4(5/3) = 21

  x +20/9 = 7 . . . . . . divide by 3

  x = 7 -(2 2/9) = 4 7/9

The solution is (x, y) = (4 7/9, 1 2/3).

Answer:

$84.50

Step-by-step explanation:

Add the amounts:

$63.48 + $52.02 = $115.50

Two $100 bills add to $200.

To find the change, subtract the total cost from the amount of money handed over.

$200 - $115.50 = $84.50

Molly should give him $84.50. Thus option B is the correct answer.

The change given must be equal to the balance left after deducting the price of the goods from the total money received.

In this case,  

Price of goods = Price of DVD player + Price of five DVDs

                         = $63.48 + $52.02

                         =$115.50

Total Money Received = 2 x $100 = $200

Therefore, Change = Total Money Received - Price of goods

                                = $200 - $115.50

                                = $84.50

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

The original painting is 120 cm wide and 85 cm tall.

and, the print is 50 cm wide.

let the print is x cm tall

So, x/ 50 = 85 / 120

120x = 4250

x= 35.41 cm

Hence, the print is 35.41 cm tall.

12: This one if fairy simple: all you need is a line that is not parallel to the line provided, and combined with it, it will provide a solution that's on that line. For example:

y = 2x

x - y = 10

13: Just find two lines that cross (6, -4).

You can use point-slope form:

y - y1 = m(x-x1)

y + 4 = m(x - 6)

then choose two equations with different m's

y = 2(x-6) - 4

y = 3(x-6) - 4

14:

Line one has a slope of two and an intercept at y=0 so it is y = 2x

Line two has a slope of one and an intercept at y=-1 so it is y = x - 1

To find the solution of the system, substitute y:

2x = x - 1

x = -1

Then plug back in:

y = 2 * -1 = -2

So the solution is: (-1, -2)

Using the table we find the constant of proportionality  is 15/8

The ratio that establishes a proportionate link between any two given values is referred to as the constant of proportionality. There are also other names for the constant of proportionality, such as constant ratio, constant rate, unit rate, constant of variation, and even rate of change.

Here,

Since from the table we have to find the constant of proportionality

So, the values of ounces of milk(x) are

30,45

and the values of amount of truffle(y) are

16,24

So for finding the constant of proportionality We take 2 cases,

a)Taking first values of x & y

x/y=30/16

x/y=15/8

b)Taking secondary values of x & y

x/y=45/24

x/y=15/8

Therefore the constant of proportionality  is 15/8

Answer:

Step-by-step explanation:

The slope of a line is defined as the change in y-coordinate divided by the change in x-coordinate between two points on the line. In this case, the change in y-coordinate between the two points is -11 - (-1) = -10, and the change in x-coordinate is 0 since both points have the same x-coordinate. Therefore, the slope of the line that passes through the points (-8, -1) and (-8, -11) is -10/0, which is undefined.

255 biology and 192 sociology textbooks were sold in a week.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

While the graph of a linear equation with two variables, x and y, creates a straight line, the graph of a linear equation with just one variable, x, forms a vertical line that is parallel to the y-axis.

Step 1:

Let x be the number of biology textbooks and y be number of sociology textbooks.

x + y = 447 ------(1)

x - y = 63 ------(2)

Step 2:

Adding (1) and (2), we get

At 55 seconds , both the plane A and plane B will have same altitude.

According to the question,

The altitude of plane A = 1500m

The altitude of plane B = 1115m

Altitude plane A gained = 19m/s

Altitude plane B gained = 26m/s

Let "x" be the number of second

Let the equation of plan A and plane B is

a(x) = m₁ x + 1500

b(x) = m₂ x + 1115

We know how fast they are gaining altitude. The are the m values

m₁ = 19

m₂ = 26

So, now we have

a(x) = 19 x + 1500

b(x) = 26 x + 1115

So , to have same altitude ,

a(x) = b(x)

=> 19 x + 1500 = 26 x + 1115

The domain of the function shown in the graph is: B. [-2, 1].

In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).

In order to determine the inverse of the given function, we would interchange input value (x) and the output value (y) as follows:

g(x) = ∛(2x + 4)

x = ∛(2y + 4)

Next, we would take the cube root of both sides of the function;

2y = x³ - 4

y = (x³ - 4)/2

y = x³/2 - 2

g(x)⁻¹ = 1/2(x³) - 2

The point-slope form with a slope of 5/2 and a point of (4,-7) is 5x-2y=34.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10. Linear equations are classified into three types: point-slope, standard, and slope-intercept.

Here,

The slope of line perpendicular to the line y +6=-2/5(x-1)
