Graph the following features:
• Slope = 2
Y-intercept = -5

The area of polygon is 10 units.

To find the area of the polygon with the given vertices, we can use the shoelace formula, which is a method for finding the area of a polygon when given its vertices in a certain order.

The shoelace formula is:

Area = (1/2) * |(x1y2 + x2y3 + x3y4 + ... + xn-1yn + xny1) - (y1x2 + y2x3 + y3x4 + ... + yn-1xn + ynx1)|

where (x1, y1), (x2, y2), (x3, y3), ..., (xn, yn) are the vertices of the polygon in a certain order.

For the given vertices, we have:

N(-2,1), P(3,1), Q(3,-1), R(-2,-1)

So the area of the polygon is:

Area = (1/2) * |(-21 + 3-1 + 3*-1 + -21) - (13 + 13 + -1-2 + -1*-2)|

Area = (1/2) * |(-2 - 3 - 3 + 2) - (3 + 3 + 2 + 2)|

Area = (1/2) * |-8 - 12|

Area = (1/2) * 20

Area = 10 square units

So the area of the polygon is 10 square units.

On solving the provided question, we can say that the inequality equation is -2y - 5 > 5/2 => -4y - 10 > 5 => -4y > 15 +. y > -15/4

An inequality in mathematics is a relationship between two expressions and or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

here,

the inequality equation is

-2y - 5 > 5/2

-4y - 10 > 5

-4y > 15

Answer:

your annual income from the investment would be $312.

Step-by-step explanation:

If you invest in 200 shares of Lerner Windows stock and receive a semiannual dividend of $0.78 a share, your annual income from the investment would be:

$0.78 x 200 shares = $156 in semiannual dividends

To find the annual income, you would multiply the semiannual dividends by 2:

$156 x 2 = $312

So, your annual income from the investment would be $312.

To find out how much time the campers took to get downstream, we can use the formula:

time = distance / speed

where distance is the distance they paddled downstream (in this case, 2 km) and speed is their average speed (in this case, 12 km/h). So we can substitute in the values we know to get:

time = 2 km / 12 km/h

To solve for the time, we can divide the distance by the speed:

time = 2/12 hours = 0.17 hours or approximately 10.2 minutes

So it takes 10.2 minutes for Nick and Chloe to get downstream.

Answer:

90 degrees

Step-by-step explanation:

For the linear equations, cx – y = 2 and 6x – 2y = 4 will have infinitely many solutions; the value of c will be 3.

cx – y = 2     eqn(1)

6x – 2y = 4    eqn(2)

The condition for infinitely many solutions is

a₁/a₂ = b₁/b₂ = c₁/c₂    eqn(3)

Here, a₁ = c, b₁ = −1, c₁ = −2 and a₂ = 6, b₂ = −2, c₂ = −4

From eqn(3), we get

c/6 = −1/−2 = −2/−4

⇒c/6 = 1/2 and c/6 = 2/4

⇒c = 3 and c = 3

Hence, for the pair of equations that will have infinitely many solutions, the value of c will be 3.

The sides 7 cm, 24 cm and 25 cm can form a right-angled triangle. The Pythagorean theorem can be used to verify this.

From Pythagorean theorem, it can be said that, the square of hypotenuse side is equal to the sum of other two sides of a right angles triangle.

Let AB, CA and BC be the sides of a right triangle. CA is the hypotenuse side, AB and BC are the base and height sides of the right triangle. The equation can then be expressed as,

CA² = AB² + BC²

Now, let us check this rule for the above given sides of the triangle.

Longest side² = Sum of squares of other two sides

25² = 24² + 7²

625 = 625

The equation y = 2x + 2 is a function. This can be determined by observing that for each x-value, there is exactly one corresponding y-value. In other words, the graph of the equation passes the vertical line test, which states that a graph represents a function if no vertical line intersects the graph more than once.

Additionally, as the given points (1,0), (0,2), (1,4), (2,6) all fall on the same line, all with a slope of 2 and y-intercept of 2, so this confirms that the equation is indeed a function.

Answer: a. To write a system of equations to find the family's costs for each kind of game according to the FCI, we can use the information provided in the problem. According to the FCI, a family of four would spend a total of $592.30 to attend two MLB games and one NBA game, and the family would spend $691.31 to attend one MLB and two NBA games. Let x be the cost of MLB games and y be the cost of NBA games. Then we can write the following system of equations:

x + y = 592.30 equation 1 represents the cost of attending two MLB games and one NBA game

2y + x = 691.31 equation 2 represents the cost of attending one MLB and two NBA games

b. We can solve the system of equations to find the cost for a family of four to attend each kind of game according to the FCI.

We can substitute equation 1 into equation 2

2y + (592.30 - y) = 691.31

2y + 592.30 - y = 691.31

2y = 691.31 - 592.30 = 99.01

y = 49.51

we know y represents cost of NBA games so 49.51 is cost of one NBA game for a family of four

x = 592.30 - y = 592.30 - 49.51 = 542.79

x represents cost of MLB games so 542.79 is the cost of one MLB game for a family of four

So, according to the FCI, a family of four would spend $542.79 to attend one MLB game, and $49.51 to attend one NBA game.

Step-by-step explanation:

The y-intercept of the line given by the equation y = -10x + 14 is (0, 14)

We know that the y-intercept of the line is nothing but the point at which the line intersects the y-axis.

To find the y-intercept, we substitute x = 0 in given equation of line and solve it for y.

In this question we have been given an equation of line y = -10x + 14

to find y-intercept substitute x = 0 in given equation.

y = -10x + 14

y = -10(0) + 14

y = 0 + 14

y = 14

This means, a line y = -10x + 14 intersects the y-axis at point (0, 14)

A geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying by a constant called the common ratio, r.

From the general formula of the nth term of the geometric sequence:

Aₙ = A rⁿ⁻¹

Given, every stop Xena makes is diminished by half of the distance she covers from the preceding. And she takes 2/3 of the time she used from the previous stop.

The problem above is a WORDED PROBLEM that involves INFINITE GEOMETRIC PROGRESSION.

As we all know, a worded problem just basically needs a thorough understanding of what is happening on the problem to translate words and phrases into algebraic phrases and equations.

Meanwhile, a geometric progression is a type of progression in which the proceeding value is greater or smaller than the previous by a ratio. Typical geometric progression problems involve ratios of greater than 1.

The above problem is an “infinite geometric progression” in which the ratio is less than 1.

Refer to the illustration below.

We first take elimination of the given.

Since both the distance and the time have infinite number of stops to complete the run, the SUM OF INFINITE GEOMETRIC PROGRESSION is

S = (A₁)/(1-r)

a1 = first term

r = ratio

Substituting the values, we have

S = (1min) / (1- (2/3))

S = 1 / (1/3)

S = 3 minutes

Generally, it is the collection of vertices with the lowest eccentricity that constitutes the centre of a connected graph, where the eccentricity of a vertex is defined as the most significant distance between that vertex and any other vertex in the graph.

Step-by-step explanation:16/12 = 1.33333333

Therefore, 2 with an exponent of 0 is equal to 1.

When a number is raised to an exponent of 0, the result is 1. This applies to any non-zero number, including 2. Therefore, 2 with an exponent of 0 is equal to 1.

The reason is that any number raised to the power of 0 is 1. This is because any number multiplied by 1 is itself, and any number raised to the power of 1 is itself. Therefore, raising a number to the power of 0 is the same as multiplying it by 1, so the result is 1.

It is also important to note that a number raised to the power of 1 is the number itself, so 2^1=2, 2^2=4, 2^3=8 and so on.

The answer to thus question is 140 degrees.

To solve this problem we must know about vertical angles,

Vertical angles are always congruent (congruent means having the same measure or size). Therefore, if one angle measures x degrees, the other angle also measures x degrees. If we know that one of the angles measures 40 degrees, we can use that information to find the measure of the other angle, which is x.

Since the angles are vertical angles, the sum of both angles will be equal to 180 degrees, therefore

x + 40 = 180

        x = 140

Therefore, the value of x is 140 degrees.
