For what value of c for which pair of linear equations cx y 2 and 6x 2y 4 will have infinitely many solutions?
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.

$0.78 a share. At that rate, what will be your annual income from the investment?
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

Find the area of the polygon with the given vertice. N(-2,1), P(3,1), Q(3,-1), R(-2,-1)
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.

one National Basketball Association (NBA) game. The family would spend $691.31 to attend one MLB and two NBA games.
a. Write a system of equations to find the family's costs for each kind of game according to the FCI. Let x be the cost of MLB games and y be
the cost of NBA games.
MLB: $
x+
NBA: $
y=592.30
b. Solve the system of equations to find the cost for a family of four to attend each kind of game according to the FCI.
y=
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:
Nick and Chloe left their campsite by canoe and paddled
downstream at an average speed of 12 km/h. They
paddled downstream for 2 km. How much time did the
campers take to get downstream? (include formula)
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.

What is the geometric sequence?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
Therefore, it would take 3 minutes for Xena to finish the run.

4.(2, –3); y = –3
5. none of the above
Answer:
1. (2, –3); x = 2---------------------------------
According to the graph, the vertex is at (2, - 3).
The axis of symmetry passes through the vertex, so its x-coordinate determines the vertical line:
x = 2The matching answer choice is 1.
Answer:
1. (2, –3); x = 2
Step-by-step explanation:
The vertex of a parabola is its turning point. This is:
the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.From inspection of the given graph, the vertex of the parabola is (2, -3).
The axis of symmetry is the vertical line that passes through the vertex and divides the parabola into two equal (symmetrical) halves.
The axis of symmetry is the x-value of the vertex.
Therefore, the axis of symmetry of the graphed parabola is x = 2.
Find the value of x in the figure. Two intersecting lines with vertical angles x degrees and 40 degrees. (1 point)
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.

What is the center theorem?
The central law expresses that even if a group is not normally distributed, the means of sufficiently large samples drawn from that group will be normally distributed.
A key conclusion of graph theory is known as the Center Theorem, which asserts that in a connected graph, the minimal degree of a vertex's degree is equal to the most significant number of vertices that can be removed from the graph while maintaining connectivity.
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. The radius of a graph is the number of vertices that make up its centre.
