According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically. The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two high-way bridges along the route the rail line serves. Although the proposed improvements are indeed needed, the authority’s plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.Which of the following, if true, would cast the most doubt on the effectiveness of the authority’s plan to finance the proposed improvements by increasing bridge tolls?(A) Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.(C) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.(D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.(E) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.

If y=5x-3 and 3x-y=-1, what is the value of y

Answers

Well if you make them both equal to y I got...
Y=-3x+1
Y=5x-3
But I don't think you can find it without the y since they are different variables. Like I know -3x and 5x are the slopes and 1 and -3 are the y intercepts but I'm stuck after that. Sorry if that wasn't any help.
Hope I helped.
1 is the answer! Hope this helps

The function f(x) = −x^2 + 48x − 432 models the profit, in dollars, a game developer makes for selling a new game, where x is the number of games sold and f(x) is the amount of profit.Part A: Determine the vertex. What does this calculation mean in the context of the problem? (5 points)

Part B: Determine the x-intercepts. What do these values mean in the context of the problem?

Answers

f(x) = −x^2 + 48x − 432

Part A

Find the zeros:

 −x^2 + 48x − 432 = 0

x^2 - 48x + 432 = 0

Factor

(x - 36 ) (x - 12 )=0

Two solutions: x = 36 and x = 12

The vertex is in x = (36 +12 )/ 2 = 24

f(24) = -(24)^2 + 48(24) − 432 = 144

The vertex is (24, 144).

Given that the coefficient of x^2 is negative, the parabole opens downward, that mean that the vertex is a maximum value.

In the context of the problem that means that the maximum profit is 144 and is obtainded when the number of games sold is 24.

Part B.

The x-intercepts are the values of x when y=0. Which we calculated above.

They are x = 24 and x = 36.

Those values are the number of games for which the profit is zero.

a square with an area of 25 in.^2 is plotted on a grid so that the bottom-left corner is at the origin. The side of the square are horizontal and vertical. A reflection over what line maps the square onto itself?

Answers

Answer:

Reflection about the vertical line x = 2.5 inches will map the square unto itself

Step-by-step explanation:

The given parameters are;

The area of the square = 25 in²

The orientation of the sides of the square are horizontal and vertical

Therefore, we have;

The area, A, of the square given by the following relation;

A = Side²

A = 25 in²

Therefore;

The area of the square = 25 = side²

The length of the sides of the square = √A = √25 = 5

The length of the sides of the square = 5 inches

The reflection of a figure that maps the figure unto itself is a reflection along the line of symmetry

One of the line of symmetry that divides the square into two similar halves is the vertical straight that passes half way through the horizontal side, which is the point 2.5 inches to the right on the x-axis with the coordinates (2.5, 0)

Therefore, reflection about the line x = 2.5 inches will map the square unto itself.

What is the circumference of 59 inches

Answers

By circumference we can safely assume that the figure is a circle. Assumingthat the given is radius, you are given the radius of a circle of 59 inches. Youare asked to find the circumference of the figure. The equation for thecircumference of a circle is C=2*pi*r. 

C=2*pi*r
C  = 2*3.723*59 inches
C  = 370.71 inches 
The circumference of a circle is 370.71 inches.

Solve the system 2x+3y=18 X-y=-1

Answers

Step-by-step explanation:

2x + 3y = 18

x - y = -1

therefore

x = y - 1

we use this identity in the first equation :

2(y - 1) + 3y = 18

2y - 2 + 3y = 18

5y - 2 = 18

5y = 20

y = 20/5 = 4

x = y - 1 = 4 - 1 = 3
