Answer:

y =12x -51

Step-by-step explanation:

slope = (y-y') / (x-x')

12 = (y- -3) / (x-4) = (y+3) / (x-4)

12*(x-4) = y+3

The number of chocolate bars that are in the vending machine are; 27 bars

We are told that the total number of chocolate bars and bags of pretzels in the vending machine is 41.

Let the number of bags of pretzels be x.

Now, we are told that number of chocolate bars is one less than twice the number of bags of pretzels. Thus;

Number of chocolate bars = 2x - 1

Thus, we can develop the algebraic expression as;

x + 2x - 1 = 41

3x - 1 = 41

3x = 42

x = 42/3

x = 14

Number of chocolate bars = 2(14) - 1 = 27 bars

The solution for y in sqrt(2x + y - 3z) = 5 is y = -2x + 3z + 25. Option A

To solve for y in the equation: sqrt(2x + y - 3z) = 5,

we need to isolate y on one side of the equation by squaring both side of the equation

=(sqrt(2x + y - 3z))^2 = 5^2

=2x + y - 3z = 25

We can solve for y by subtracting 2x and adding 3z to both sides:

y = 25 - 2x + 3z

y = -2x + 3z + 25

Therefore, the solution for y is y = -2x + 3z + 25

The solution to the system of equations is x = -3 and y = -4.

To solve the system of equations:

Equation 1: 2x - y = -10

Equation 2: 3x + 2y = -1

We can use the method of substitution or elimination to find the values of x and y.

Let's use the method of elimination:

Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(2x - y) = 2(-10)

4x - 2y = -20

Now, we can eliminate y by adding Equation 2 and the modified Equation 1:

(3x + 2y) + (4x - 2y) = -1 + (-20)

7x = -21

x = -3

Substitute the value of x into Equation 1 to solve for y:

2(-3) - y = -10

-6 - y = -10

y = -10 + 6

y = -4

Therefore, the solution to the system of equations is x = -3 and y = -4.

Answer:

x = 2

y = 1

Step-by-step explanation:

-2x-3y=-7, y=6x-11

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-2x - 18x = -40

-20x = -40

x = 2

y = 6(2) - 11

y = 12 - 11

y = 1

Answer:

x = 2, y = 1

Step-by-step explanation:

We have a system of equations:

-2x - 3y = -7

y = 6x - 11

Substitute the given value of y into the equation -2x - 3y = -7

-2x - 3 * (6x - 11) = -7

-20x = -7 - 33

-20x = - 40

x = 2

Substitute the given value of x into the equation y = 6x - 11

y = 6x - 11

y = 6 * 2 - 11

y = 1

Answer:

x = 7.423891441

Step-by-step explanation:

Hey There!

So they want you to solve for x using law of sines

Law of sines states that sin ( an angle) divided by it's opposite side equals sin( a different angle) divided by its opposite side

so basically

\(\frac{sin23}{x} =\frac{sin90}{19}\)

now we can solve for x

step 1 multiply each side by sin 23

the fraction would split and it would be

\(x=\frac{19sin23}{sin90}\\x = 7.423891441\)

So we can conclude that x = 7.423891441

There is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.

In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.

To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.

A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.

Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To earn an average score of 90, the score on the fourth test needs to be 98.

The core value of a set of data is expressed mathematically as the average of a list of data. It is defined mathematically as the ratio between the total number of units in the list and the sum of all the data. The term "mean" in statistics also refers to the average of a particular set of numerical data.

Given the score of the first three tests as:

91, 84, 87.

The average is given by the following formula:

Average = Sum of scores ÷ total number of tests

Let us suppose the score of fourth test as x.

Given that A = 90:

90 = (91 + 84 + 87 + x) ÷ 4

x = 98

Hence, the score on the fourth test must be equal to 98, to get an average score of 90.

To evaluate f(x) + f(2), we first need to find f(x) and f(2) by plugging in x = x and x = 2 into the given function:

f(x) = -8x - 4

f(2) = -8(2) - 4 = -16 - 4 = -20

Now we can substitute these values into f(x) + f(2):

f(x) + f(2) = (-8x - 4) + (-20)

Simplifying the expression, we get:

f(x) + f(2) = -8x - 24

Therefore, f(x) + f(2) = -8x - 24.

The slope of the line passing through points A and B is 1/3.

The formula for the slope of a line to find the slope passing through points A and B. The formula is:

slope = (change in y) / (change in x)

Let's label the coordinates of point A as (x₁, y₁) and the coordinates of point B as (x₂, y₂).

Then, substitute the values and calculate the slope:

slope = (y₂ - y₁) / (x₂ - x₁)

slope = (3 - 2) / (3 - 0)

slope = 1 / 3
