Substitution y=2x - 6
y= 5x+8

The proportional equation that is on the graph can be written as:

y = 0.83*x

Remember that a general proportional equation is written as:

y = k*x

Where k is the constant of proportionality.

To find the value of the constant of proportionality, we need to identify one point that lies on its graph. For example, we could use the point (0.6, 0.5)

Where x = 0.6

y = 0.5

Replacing that in the general proportional equation we will get:

0.5 = k*0.6

0.5/0.6 = k

0.83 = k

Then the proportional equation is:

y = 0.83*x

A table can be read from top to bottom or left to right. When reading a table across a row, you should read the data from left to right.

In mathematics, a sequence is a list of items that is in a particular order (or events). It has members and is comparable to a set (also called elements, or terms). The amount of ordered elements determines how long the sequence is (potentially infinite). The four basic types of sequences that you should be knowledgeable about are arithmetic sequences, geometric sequences, quadratic sequences, and special sequences. A number sequence is a collection of integers connected by a pattern. If you understand the rule, you can determine the subsequent numbers in the sequence. In this case, there is a 6 difference between each number. As a result, the rule for this sequence is to add 6 each time.

The value of x is that will ensure that quadrilateral VWXY is parallelogram is 0.25.

•A polygon called a quadrilateral has four sides, four angles, and four vertices. Parallelograms, Squares, Rectangles, and Rhombuses are the different types of quadrilaterals. Parallelograms also include squares, rectangles, and rhombi.

• All quadrilaterals have a few characteristics. Parallelograms characteristics are each of them has four vertices, each side has four sides, 360 degrees is the sum of all interior angles and two diagonals are present.

•There are regular and irregular quadrilaterals. An ordinary quadrilateral must have four equal sides, four equal angles, and diagonals that cross one another. Only the square can fulfill each of these requirements of a quadrilateral.

As we know that the opposite angles of a parallelogram are equal

hence 10x + 27 = 2x + 29

8x = 2

x = 0.25

Hence, the angles are 29.5

Let the value of angle v and x be a

Now using angle sum property of a parallelogram

29.5 +29.5 + a + a = 360

2a = 301

a = 150.5

hence angle V is 150.5

Answer:

y = 13

Step-by-step explanation:

given (7, 33 ) is a solution of the top equation, then

x = 7, y = 33 satisfies the equation , that is

33 = 7a + 5 ( subtract 5 from both sides )

28 = 7a ( divide both sides by 4 )

4 = a

then

y = 4x + 5 ← top equation

substitute y = 4x + 5 into the other equation

9x + 2(4x + 5) = 44

9x + 8x + 10 = 44

17x + 10 = 44 ( subtract 10 from both sides )

17x = 34 ( divide both sides by 17 )

x = 2

substitute x = 2 into the top equation for value of y

y = 4x + 5 = 4(2) + 5 = 8 + 5 = 13

The exponential function is y = 1200(1.04)^t and the investment amount after 16 years is $2247.58.

What is exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

Jayden invests $1,200 in a savings account. Each year, the value increases by 4%.

Let t = time in years

Let y = amount of money invested in savings account

Start with $1200 and each year add 4% interest to the amount in the bank.

1st year: Interest = 1200 × (0.04) = $48

This is added to the previous amount -

= $1200 + $1200 × (0.04)

= $1200 (1+0.04)

= $1200 (1.04)

= $1248

2nd year: Previous amount + interest on the previous amount

= $1248 (1+0.06)

= $1248 (1.06)

= $1297.92

So, the exponential formula becomes -

y = 1200(1.04)^t

Now, to find the value of investment after 16 years, substitute t = 16.

y = 1200(1.04)^t

y = 1200(1.04)^16

y = 1200(1.87298125)

y =$2247.58

Therefore, the value of investment after 16 years is $2247.58.

Question 49
[tex]\mathrm{Choice \; (D)\;\;-1}[/tex]

Step-by-step explanation:

The imaginary variable i is [tex]\sqrt{-1}[/tex] and [tex]i^2 = -1[/tex]

For the unnumbered first question we have

the equation
[tex]\dfrac{1}{1-i}[/tex]

Multiply numerator and denominator by [tex]i + 1[/tex]

[tex]\rightarrow \dfrac{1\cdot \left(1+i\right)}{\left(1-i\right)\left(1+i\right)}\\\\\\= \dfrac{1 + i}{1 - i^2} \;\;\;\;\;\;\;since \;(a +b)(a-b) = a^2 - b^2\\\\\textrm{Since $i^2 = -1$, the denominator becomes:}\\\\1-i^2 = 1 -(-1) = 2\\\\\\[/tex]

Therefore ,

[tex]\dfrac{1}{1-i} = \dfrac{1 + i}{2}\\\\= \dfrac{1}{2} + \dfrac{i}{2}\\\\[/tex]

Solve [tex](x, y)[/tex]  for [tex]2y\:+\:xi\:=\:4+x-i[/tex] for  [tex]$x,y\in\mathbb{R}$[/tex]

For the equation

[tex]2y\:+\:xi\:=\:4+x-i[/tex]

Move the the x and i terms from the right to left side:

[tex]2y + xi - x + i = 4\\\\2y - x +xi + i =4\\\\[/tex]

Since this works out to a real number, the imaginary part is 0

So

[tex]xi + i = 0\\\\xi = -i\\\\x = \dfrac{-i}{i}\\\\x = -1[/tex]

and the real part

[tex]2y - x = 4[/tex]

Substitute for x = -1 in the above to get
[tex]2y -(-1) = 4\\\\2y + 1 = 4\\\\2y = 4-1\\\\2y = 3\\\\y = \dfrac{3}{2}\\\\[/tex]

[tex](x, y) = \left(-1, \dfrac{3}{2}\right)[/tex]

Since i² = -1 this works out to:

The GCF of 10 and 4x is 2.

The greatest common factor (GCF) of two or more numbers is the largest number that divides evenly into each of them. Factoring a number means breaking it down into its prime factors. That is;

10 = 2 * 5 , we can see that 2 and 5 are the prime factors of 10.

4x = 4 * x, we can see that 4 and x are the prime factors of 4x.

Since 2 is the only common factor between 10 and 4x, we can conclude that 2 is the GCF of 10 and 4x.

It means that 2 is the greatest number that divides into both 10 and 4x with a remainder.

To solve complex fractions there are two methods -

1 - Divide the numerator by the denominator by multiplying the numerator by the reciprocal of the denominator and then simplify further if necessary.

2 - Multiply the numerator and denominator of the overall complex fractions and then simplify further if necessary.

A rational expression with a fraction in the numerator, denominator, or both is referred to as a complex fraction.

There are two ways to solve a complex fraction -

method 1 : Take an example - (1/3-1/4)/(1/8+1/2)

step1; If necessary, combine the denominator and numerator into a single fraction.

Add the numerator -

=1/3-1/4

=(4-3)/12

=1/12

Add the denominator -

=1/8+1/2

=(1+4)/8

=5/8

Combine back to form a complex fraction -

=(1/12)/(5/8)

Step 2: Multiply the numerator by the denominator's reciprocal, then divide the result by the denominator.

Step 3: Simplify the rational expression if necessary.

=(1/12)×(8/5)

=8/60

=2/15

Method 2: Take an example - [(2x+1)/(x^2-25)]/[(4x^2-1)/(x-5)]

Step 1 - Divide the LCD of the smaller fractions by the numerator and denominator of the total complex fractions.

(x^2-25)=(x+5)(x-5)

The denominator of the denominator’s fraction  has the following factor -

(x-5)

Using the highest exponent and combining all the other factors, we arrive at the LCD shown below for all the little fractions -

(x+5)(x-5)

By multiplying the LCD by the numerator and denominator -

=[{(2x+1)/(x+5)(x-5)}×(x+5)(x-5)]/[{(2x+1)(2x-1)/(x-5)}×(x+5)(x-5)]

=(2x+1)/(2x+1)(2x-1)(x+5)

Step 2 - Simplify the rational expression if necessary.

=(2x+1)/(2x+1)(2x-1)(x+5)

=1/(2x-1)(x+5)
