Considering the given matrix, it is found that the number of solutions of the system of equations is given by:

B. 1.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The matrix form of the system can also be written as:

[tex]\left[\begin{array}{cc}1&0\\0&1\end{array}\right]\left[\begin{array}{c}x\\y\end{array}\right] =  \left[\begin{array}{c}5\\6\end{array}\right][/tex]

Applying the multiplication of the matrices, we have that:

Hence the system has one solution, given by (5,6), and option B is correct.

The answer is "2.2 h"

Step-by-step explanation:

Speed of Train B:

[tex]= \frac{3}{2} \times 70 \ mph \\\\= 105 \ mph[/tex]

Train B is then moving on:

[tex]= \frac{200 \ miles}{ 105 \ mph} \\\\= 1.905 \ h\\[/tex]

Then it takes Train A to the left:

[tex]\to 1.905\ h + 20 \ min \\\\= 1.905 \ h +0.333 \ h \\\\= 2.238 \ h[/tex]

To get train B to the reference point of train A = 2.2 h

Answer:

x = 6 + 4.796i  and  x = 6 - 4.796i

Step-by-step explanation:

For this problem, we will simply apply the quadratic formula to find the values of x.  The quadratic formula is as follows:

x = [-b +/- sqrt(b^2 - 4ac)] / 2a

Using the formula let's find the values of x.

x^2 - 12x - 6 = -65

x^2 - 12x - 6 + 65 = -65 + 65

x^2 - 12x + 59 = 0

The coefficient of x^2 is a, the coefficient of x is b, and the constant 59 is c.

Hence, for our formula we have the following values:

a = 1

b = -12

c = 59

x = [-b +/- sqrt(b^2 - 4ac)] / 2a

x = [-(-12) +/- sqrt( (-12)^2 - 4(1)(59) ) ] / 2(1)

x = [ 12 +/- sqrt ( 144 - 236 ) ] / 2

x = [ 12 +/- sqrt ( -92 ) ] / 2

x = [ 12 +/- sqrt ( -4 * 23 ) ] / 2

x = [ 12 +/- 2i sqrt(23) ] / 2

x = 6 +/- i sqrt(23)

Hence from the formula, we have two possible values for x, both complex solutions.  Note, i is an imaginary number.

x = 6 + i sqrt(23)  and  x = 6 - i sqrt(23)

x = 6 + 4.796i  and  x = 6 - 4.796i

Cheers.

W = 1.8 kg

Step-by-step explanation:

Zoé bought 3 cheeses, 3/5 each. How many Kilograms of cheese does he have in total?

Weight of each cheese is 3/5 kg. Zoe bought 3 cheeses. We need to find the weight of cheese in total.

To find weight of 3 cheeses, we will multiply 3 by 3/5 such that:

[tex]W=3\times \dfrac{3}{5}\\\\W=1.8\ kg[/tex]

So, the weight of cheese in total is 1.8 kg.

Answer:

[tex]x=-52[/tex]

Step-by-step explanation:

multiple everything by 3 to get rid of the fractions

[tex]3(1/3x-2/3=-18)\\1x-2=-54\\[/tex]

rewrite

[tex]x-2=-54[/tex]

add 2 to both sides

[tex]x-2+2=-54+2\\x=-52[/tex]

Answer:

[tex]x=-52[/tex]

Step-by-step explanation:

[tex]\frac{1}{3} x-\frac{2}{3} =-18[/tex]

Add [tex]\frac{2}{3}[/tex] to both sides of the equation:

[tex]\frac{1}{3} x=-18 +\frac{2}{3}[/tex]

Simplify [tex]-18+\frac{2}{3}[/tex] by multiplying [tex]-18[/tex] in fraction form [tex]-\frac{18}{1}[/tex] to get a common denominator so you can add the two fractions:

[tex]-\frac{18}{1}[/tex] × [tex]\frac{3}{3}=-\frac{54}{3}[/tex]

Now add the two fractions:

[tex]-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}[/tex]

Now write the simplified equation:

[tex]\frac{1}{3} x=-\frac{52}{3}[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]\frac{1}{3}[/tex]:

[tex]x=-\frac{52}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]

Use the reciprocal of the dividend ([tex]\frac{1}{3}[/tex]), and multiply by your divisor:

[tex]x=-\frac{52}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]x=-\frac{156}{3}[/tex]

Simplify the fraction by dividing [tex]-156[/tex] into [tex]3[/tex]:

[tex]x=-52[/tex]

Answer:

There is no number for the hundreds, tens, and ones place, so put 000 with no comma after, like this.

The number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters is 6,760,000, option a is correct.

To determine the number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters, we need to consider the possibilities for each element.

For the numbers, we have 10 options (0-9) for each of the four positions, resulting in a total of [tex]10^4 = 10,000[/tex] combinations.

For the letters, we have 26 options (A-Z) for each of the two positions, resulting in a total of [tex]26^2 = 676[/tex] combinations.

To find the total number of different plates, we multiply the number of possibilities for each element:

[tex]10,000 \times 676 = 6,760,000[/tex].

Hence, option a is correct.

Step-by-step explanation:

Given the following information:

First three hours of typhoon: rate of Rainfall. = 25mm per hour

Typhoon slows down for an hour : then Rainfall began again at a constant rate of 20 mm per hour for the next 2 hours

Piecewise function which models Rainfall ad a function of time

Amount of Rainfall as a function of time = f(t)

f(t) = 25t ; if t≤ 3

When typhoon slowed down for an hour :

f(t) = 0;

f(t) = 25*3 ; for t ∈ (3, 4)

Then Rainfall at a constant rate of 20mm for another 2 hours

Loretta Adman needs to find the center of the triangle  formed by the three roads.

What is Center, Incenter and Circumcenter of the triangle?

Incenter I, whose point is equidistant from the triangle's sides, and circumcenter O, whose point is equidistant from each of the triangle's vertices. A triangle center is a point in the plane that resembles the centers of squares and circles in some ways, meaning that it is roughly in the centers of the figure.

Given:  Three towns are linked by three straight roads.

Loretta Adman has created a three-sided billboard that she wants to position as close as possible to all three roads.
