After solving the system of equations we get the values as:

Given the equations are as follows, we need to solve them using multiplication method:

take c+3t=7

rearrange the terms.

c = 7-3t

substitute c value in other equation.

3(7-3t)-2t=-12

21-9t-2t=-12

21-11t=-12

-11t = -12-21

-11t=-33

t=33/11

t=3

now substitute t value in c = 7-3t

c = 7-3(3)

c=7-9

c=-2

hence t and c values are 3 and -2.

take 5x – 4z = 15

5x = 15+4z

x=15+4z/5

substitute x value in other equation.

-3(15+4z/5)+2z=21

-45-12z+10z=105

-45-2z=105

-2z=105+45

z=-75

substitute z value in x=15+4z/5

x=15+4(-75)/5

x=-57

hence x and z values are -57 and -75.

consider, -4m+3n=50

3n = 50+4m

n=50+4m/3

substitute n value in other equation.

2m+n=10

2m+50+4m/3 = 10

6m+50+4m=30

10m=30-50

10m=-20

m=-2

substitute m value in n=50+4m/3

n = 50+4(-2)/3

n = 50-8/3

n = 42/3

n = 14

hence m and n values are -2 and 14.

consider 2p - 4q = 18

2p = 18+4q

p = 9+2q

substitute p value in other equation.

-3p+5q=22

-3(9+2q)+5q=22

-27-6q+5q=22

-27-q=22

-q = 22+27

q = -49

now p = 9+2q

p = 9+2(-49)

p = 9-98

p=-89

hence p and q values are -89 and -49.

consider 3a + 4b = 51

3a = 51-4b

a=51-4b/3

substitute a value in other equation.

2(51-4b/3)+3b=37

102-8b+9b=111

102+b=111

b=111-102

b=9

now, a=51-4(9)/3

a = 51-36/3

a = 15/3

a = 5

hence a and b value are 5 and 9.

Therefore, we solved the required system of equations.

The number of words of the book Jimmy reads os 21,356, and the number of words of the book Bob reads is one-and-a-half times (that is, 1.5x) as many words, so to find the number of words Bob reads, we just need to multiply the number of words of Jimmy's book by the factor of 1.5:

Given function,

f(x) = 6x - 6

or

y = 6x -6

The inverse of a function is calculated by replacing the values of x and y

therefore

Inverse (y = 6x - 6)

x = 6y - 6

x + 6 = 6y

6y = x + 6

y = x/6 + 6/6

y = 1/6*x + 1

or

g(x) = 1/6*x + 1

Hence, both are inverse of each other.

Saving account that pays 5% interest compounded daily is much better than the account that pays 5% interest compounded semiannually.

As given in the question,

Interest rate = 5%

Types of account = Saving account

Pays the interest in two forms :

Compounded semiannually and Compounded daily

Saving account that pays 5% interest compounded daily is much better than the account that pays 5% interest compounded semiannually.

Reason :

Frequency of interest given on compounded daily is much higher and increase the amount much faster as compare to compounded semiannually.

When interest compounded daily generate 365 compounding periods a year, where as compounded semiannually generates two times in a year.

Therefore, saving account that pays 5% interest compounded daily is much better than the account that pays 5% interest compounded semiannually.

This is written in Interval notation.

In "Interval Notation" we just write the beginning and ending numbers of the interval, and use:

a) [ ] a square bracket when we want to include the end value, or

b) ( ) a round bracket when we don't.

Because the interval given uses round brackets, the inequality will contain all real numbers between negative infinity and -5, but not including negative infinity and -5.

Therefore, the inequality will be:

If the value of B increases, the period of the function decreases, and the frequency of the function increases. When the value of B is negative, the graph of the function reflects over the y-axis.

Let the tangent function be f(z) = tan (Bz)

The period exists [tex]$P=\frac{\pi}{|B|}$[/tex]

The frequency exists [tex]$F=\frac{1}{P}=\frac{|B|}{\pi}$[/tex].

The period exists inversely proportional to B, therefore, as B increases, the period decreases.

Frequency exists inversely proportional to the period, therefore, as the period decreases, the frequency increases.

When B is negative, we get f(z) = tan -Bz = f(-z), therefore, the function exists reflected over the y-axis, as the graph at the end of the answer shows, with f(z) exists red(B positive) and f(-z) exists blue(B negative).

As the value of B increases, the period of the function decreases, and the frequency of the function increases. When the value of B exists negative, the graph of the function reflects over the y-axis.

Step 1. We are given the graph of a line and we need to find the equation of the line parallel to it that has an x-intercept of -3.

Since the new line will be a parallel line it means that it will have the same slope. Therefore, our first step is to find the slope of the current line.

Given any line, we find the slope as shown in the following example diagram:

Step 2. Using the previous method, the slope of our line is:

The new line will have the same slope of 2/3.

Step 3. We are also told that the x-intercept of the new line is -3, which means that the new line will cross the y-axis at x=-3, that point is:

(-3,0)

We will label that point of our new line as (x1,y1):

Step 4. So far, we know that the new line will have a slope of 2/3:

And that it includes the point (-3,0) where x1=-3 and y1=0.

To find the equation, we use the point-slope equation:

We have a trapeze and, we need to find the probability that a randomly chosen point is the figure lies in the shaded region

STEP BY STEP EXPLANATION:

To find the probability, we must divide the area of the shaded region by the total area of the trapeze

- Total area:

To calculate the total area, we must use the formula for the area of a trapeze

Where, b1 and b2 are the bases and h is the height

Then, analyzing the trapeze we can see that b1 = 20, b2 = 14 and h = 12

So, the total area is 204 square units

- Shaded area:

To find the shaded area, we must subtract the no shaded area from the total area.

We can see that the no shaded area is a rectangle with width = 14 and height = 12

Now, using the formula for the area of a rectangle

Then, subtracting the area of the rectangle from the total area

So, the no shaded are is 36 square units.
