What is the value of x

Answer:

y = 2x + 5

Figure 505

Step-by-step explanation:

(3,11) ( 4,13)

Find the slope

Change in y over the change in x

[tex]\frac{13-11}{4-3}[/tex] = [tex]\frac{2}{1}[/tex] = 2

slope (m) is 2.

Part A

Find the y -intercept

m = 2

x = 3     from the point (3,11)

y = 11    from the point (3,11)

y = mx + b  Substitute what I know and solve for b

11 = (2)(3) + b

11 = 6 + b  Subtract 6 from both sides

11 - 6 = 6 -6 + b

5 = b

The y intercept (b) is 5

y = mx + b

y = 2x + 5

Part B

y =  2x + 5

1015 = 2x + 5  Subtract 5 from both sides

1015 - 5 = 2x + 5 - 5                                                    

1010 = 2x  Divide both sides by 2

The population of the Boom town increased by 25% compared to last year, present population is 6000 then last year population is equal to 4800.

As given in the question,

Given population of the present year is equal to 6000

Let us consider 'x' be the last year population.

Increased in population compared to last year = 25%

Required equation is given by :

x + (25/100)x = 6000

⇒ (125 / 100 )x = 6000

⇒ x = ( 6000 × 100 ) / 125

⇒ x = 4800

Therefore, the population of the last year as per given data of the present year is equal to 4800.

The above question is incomplete, the complete question is:

Compared to last year, the population of Boom Town has increased by 25%. The population is now 6,000. What was the population last year?

Answer:

119 cm²

Step-by-step explanation:

Area of white triangle:

             base = 9 cm

           height = 14 cm

       [tex]\sf \boxed{Area \ of \ triangle = \dfrac{1}{2}*base *height}[/tex]

                                    [tex]\sf =\dfrac{1}{2}*9*14\\\\ = 9*7\\\\= 63 \ cm^2\\[/tex]

Area of trapezium:

          [tex]\sf \boxed{Area \ of \ trapezium =\dfrac{(a+b)*h}{2}}[/tex]

Here, a and b are the parallel sides of trapezium & h is the height.

           a = 9 cm ; b = 17 cm and h =14 cm

[tex]\sf Area \ of \ trapezium = \dfrac{(9+17)*14}{2}[/tex]

                           [tex]= \dfrac{26*14}{2}\\\\\\=13*14\\\\= 182 \ cm^2[/tex]

Area of shaded region = area of trapezium - area of white triangle

                                      = 182 - 63

                                      = 119 cm²

Answer:

area of shaded region = 119 cm²

Step-by-step explanation:

the outer figure has one pair of parallel sides and is a trapezium.

the shaded area (A) is calculated as

A = area of trapezium - area of white triangle

the area of a trapezium is calculated as

area = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 14 , b₁ = 9 , b₂ = 17 , then

area = [tex]\frac{1}{2}[/tex] × 14 × (9 + 17) = 7 × 26 = 182 cm²

the area of the triangle is calculated as

area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 9 and h = 14 , then

area = [tex]\frac{1}{2}[/tex] × 9 × 14 = 4.5 × 14 = 63 cm²

then area of shaded region (A) is

A = 182 - 63 = 119 cm²

It is "3 pairs" not "3 pair", because a pair is a set of two things, so if you have 3 of them it would be 3 sets of two things or 3 pairs.

The function's value at x = 1, y = - 1 Or f(1) = -1.

The value of exponential 2 is 2^2, or 4. This means two multiplied by itself two times or squared.

Exponential notation is a way of expressing a number, usually greater than 10, as a base number, the number 2 in this case, raised to a power, which in this case is 2. Therefore, exponential 2 is written as 2^2, which means two multiplied by itself two times or squared.

For example, if we wanted to find the value of exponential 8, we could easily calculate 2^8, or 256, which is much faster than multiplying 2 by itself 8 times. Exponential notation is also helpful when calculating exponents with variables.

For example, if we wanted to find the value of 3^x, we could use exponential notation to find the answer quickly. In summary, exponential notation is a useful tool for quickly finding the value of a number raised to a power.

The equation in slope intercept form is

y = 5/2x + 5

One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.

Any location that is not on the line will not fulfill the coordinates.

This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.

Two points on the line are (-2,0) and (0,5)

The slope intercept form is

y = mx + c

so when y = 0 and x = -2

0 = -2(m) + c

or,  2m -c = 0 ..(i)

again when x= 0 y = 5

5 = 0*m + c

c = 5

so putting c= 5 in equation (i) we get

m = 5/2

so the equation in slope intercept form is

y = 5/2x + 5

For the given line segment, the value of HJ is 32 and hence option a is the correct answer.

Two unique points on a line define the boundaries of a line segment. A line segment is sometimes referred to as a section of a line that links two places.

Given that:

GJ = 56

[tex]\frac{GH}{HJ} =\frac{3}{4}[/tex]

The line segment GHJ = GJ can be written as follows:

GJ= GH +HJ

From the given ratio we know that:

The balance on the credit card after three years would be $20,111.25.

What is continuous compound interest?

Continuous compounding means that there is no limit to how often interest can compound. Compounding continuously can occur an infinite number of times, meaning a balance is earning interest at all times.

The balance on the credit card after three years can be calculated using the formula for continuous compound interest:

A = P * e^(rt)

where A is the final balance, P is the initial principle (the amount of the loan), r is the annual interest rate as a decimal, and t is the number of years.

In this case, P = $12,500, r = 0.1599 (15.99% as a decimal), and t = 3.

Plugging these values into the formula:

A = $12,500 * e^(0.1599 * 3)

A = $12,500 * e^0.4797

A = $12,500 * 1.6089

A = $20,111.25

in the form ax²+bx+c, in which a, b, and c are constants, the value of given quadratic equation a+b+c is 0.

Simplification is the process of making an expression or equation simpler, while still maintaining its meaning or function. This can be done by combining like terms, combining or removing unnecessary elements, or applying mathematical rules or identities.

For example, in algebra, simplifying an expression might involve combining the coefficients of similar terms (such as 2x + 3x = 5x), or factoring out a common factor from multiple terms (such as [tex]2x^2 + 4x = 2x(x+2).[/tex]

The goal of simplification is to make the expression or equation easier to understand, manipulate, or solve.

The expression given is already in the form ax^(2) + bx + c, so we can simply add the coefficients of the x^(2), x and constant terms to find the value of a+b+c:

[tex](2x^{(2)} -3x+1)-(-2x^{(2)}-3x+2) = 2x^{(2)} - (-2x^{(2)}) + (-3x) - (-3x) + 1 - 2[/tex]

a+b+c = 2 - (-2) + (-3) - (-3) + 1 - 2 = 2 + 2 - 3 - 3 + 1 - 2 = 0

Therefore, the value of a+b+c is 0.
