The Answer is A

The equation for a parallel street that passes through the given point is y = 4x + 12

From the question, we are to determine the equation of the street that is parallel to the first street

NOTE: Two lines are parallel if they have equal slopes.

Thus,

We will determine the slope of the first street.

From the given information,

The street passes through the points (4, 7) and (3, 3)

Using the formula,

Slope = (y₂ - y₁)/(x₂ - x₁)

x₁ = 4

y₁ = 7

x₂ = 3

y₂ = 3

∴ Slope = (3 -7)/(3 -4)

Slope = -4/-1

Slope = 4

Now,

For the equation of the parallel street

The street passes through the point (-2, 4)

Since, the street is parallel to the first street,

Slope = 4

Using the point-slope form

y - y₁ = m(x - x₁)

y - 4 = 4(x - -2)

y - 4 = 4(x + 2)

y - 4 = 4x + 8

y = 4x + 8 + 4

y = 4x + 12

Hence, the equation for a parallel street that passes through the given point is y = 4x + 12

The coordinates of its center will be (2,10)

(x - h)²+ (y - k)² = r² is the formula for the equation of a circle, where (h, k) stands for the circle's center's coordinates and r for the radius.

A circle with a radius of r and a center is represented as

(x - a)² + (y - b)² = r² where (a, b) is the center of the circle.

Circle passes points (-4, 2) and (2, 0):

Both (-4 - a)² + (2 - b)² and (2 - a)² + (-b)² are equal to r²

Currently, the center's x coordinate (a) is 2 due to the tangent at (2, 0)

The equations then read:

6² + (2 - b)² = r²

b² = r²

⇒ 36 + (2 -b)² -b² = 0

⇒ 36 + 4 + b² - 4b - b² = 0

⇒ 4b = 40

⇒ b = 10.

So, the center is (2,10)

The possibility of an event or outcome occurring conditional on the occurrence of a prior event or outcome is known as conditional probability. The conditional probability is calculated by multiplying the probability of the previous event by the present probability of the upcoming, or conditional, occurrence.

Contrast Unconditional probability with conditional probability. The possibility that an event will occur regardless of whether any previous occurrences have occurred or any other circumstances are present is known as Unconditional probability.

Answer: 10x + 19 = 519              x = 50

Step-by-step explanation:

We are looking for the number of students that rode in each bus, so first lets subtract out those that drove in cars.

519-19=500

So 500 students rode on 10 buses. So now we divide the students onto the buses.

500/10 = 50

Each bus drove 50 students.

An equation to represent the total number of students as a function of those on the buses would be

10x + 19 = 519

x = 50 (the number of students on each bus)

Final answer:

The best term that describes the number of solutions that will maximize the function is one optimal solution (a)

A practicable solution is one that complies with all limitations and specifications. When all of the requirements and constraints cannot be satisfied by any combination of decision variable values, a solution is deemed to be infeasible. The parabola's highest or lowest point represents the ideal value. If only the parabola expands down words, the optimal value, also known as the vertex of the parabola, would be maximal. The minimal value is one opening upwards. The vertex's "Y" coordinate is it.

The length of line AB with coordinates A (-5, -2) and B (7, 4) is;  6√5 units

The formula for distance of a line between two coordinates is;

D = √[(x2 - x1)² + (y2 - y1)²]

From the coordinates given as A (-5, -2) and B (7, 4), we can say that;

x1 = -5

x2 = 7

y1 = -2

y2 = 4

Thus;

D = √[(7 - (-5))² + (4 - (-2))²]

D = √(12² + 6²)

The slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.

Given the following data:

Points on x-axis = (-12, 6).

Points on y-axis = (14, -1).

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given points into the formula, we have;

Slope = (6 + 12)/-1 - 14)

Slope = -18/15

Slope = -6/5

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

At point (-12, 14), we have:

14 = -6/5(-12) + c

8 = 72/5 + c

40 = 72 + 5c

5c = 72 - 40
