Solve the system by graphing.

igor_vitrenko [27]

Answer:

Hi There the correct answer is {x,y} = {-1,-10}

System of Linear Equations entered :

[1] 3x - y = 7

[2] 4x - 2y = 16

Graphic Representation of the Equations :

y + 3x = 7 -2y + 4x = 16

Solve by Substitution :

// Solve equation [1] for the variable y

[1] y = 3x - 7

// Plug this in for variable y in equation [2]

[2] 4x - 2•(3x-7) = 16

[2] -2x = 2

// Solve equation [2] for the variable x

[2] 2x = - 2

[2] x = - 1

// By now we know this much :

x = -1

y = 3x-7

// Use the x value to solve for y

y = 3(-1)-7 = -10

Solution :

{x,y} = {-1,-10}

Hope it helps!

A medical researcher needs 37 people to test the effectiveness of an experimental drug. If 101 people have volunteered for the t

Rashid [163]

Answer:

The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!\cdot (n-k)!}$

Compute the number of ways to select 37 people from 101 as follows:

${101\choose 37}=\frac{101!}{37!\cdot (101-37)!}$

$=\frac{101!}{37!\times 64!}\\\\=\frac{101\times 100\times 99\times....64!}{37!\times 64!}\\\\=5397234129638871133346507775$

Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.
