\frac{1,254}{1,254+1,462} /  \frac{1,462}{1,254+1,462}\\ \frac{1,254}{2,716} / \frac{1,462}{2,716}\\\frac{627}{1,358} /  \frac{731}{1,358}

Chance of boy: 627/1,358

Chance of girl: 731/1,358

What is the solution to the system of equations below? y = -3X+5 and y=4x-2 (1, 2) (1, –18) (–1, 8) (–1, –6)
Maurinko [17]

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

y = - 3x + 5 → (1)

y = 4x - 2 → (2)

Substitute y = 4x - 2 into (1)

4x - 2 = - 3x + 5 ( add 3x to both sides )

7x - 2 = 5 ( add 2 to both sides )

7x = 7 ( divide both sides by 7 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = (4 × 1) - 2 = 4 - 2 = 2

Solution is (1, 2 )

I really am confused on how to write a proof.
kvasek [131]

Since ABCD is a parallelogram, the opposite sides will be parallel and equal,

\begin{gathered} AB=CD \\ BC=AD \end{gathered}

Consider that AC acts as a transversal to the parallel lines AB and CD, so we can write,

\begin{gathered} \angle CAD=\angle ACB\text{ (Alternate Interior Angles)} \\ BC=AD\text{ (Opposite sides of parallelogram)} \\ \angle ADB=\angle CBD\text{ (Alternate Interior Angles)} \end{gathered}

So by the ASA criteria, the triangle AED is congruent to the triangle CEB,

Then the corresponding parts of the triangles will be equal,

\begin{gathered} AE=CE \\ BE=DE \end{gathered}

Hence Proved.

What does the equation inverse of the function found in part b represent in the contract of the problem ? explain your answer .
gavmur [86]

Answer:

f^{-1}(x) =\frac{x}{3} - 5

The inverse function is to calculate the number of rides; given the amount paid

Step-by-step explanation:

Given

Admission = 15

Ride = 3 per ride

Required

Explain the inverse function

First, we calculate the function

Let x represents the number of rides

So:

f(x) = Admission + Ride * x

f(x) = 15 + 3 * x

f(x) = 15 + 3x

For the inverse function, we have:

y = 15 + 3x

Swap x and y

x = 15 + 3y

Make 3y the subject

3y = x - 15

Make y the subject

y =\frac{x}{3} - 5

Replace y with the inverse function

f^{-1}(x) =\frac{x}{3} - 5

The above is to calculate the number of rides; given the amount paid
