How do I solve it and what would be the answer

Given from the number line:

D = -2 and F = 13

So, the distance DF = 13 - (-2) = 13 + 2 = 15

1) find E such that, DE : EF = 2 : 1

so,

so, x : (15 - x) = 2 : 1

x = 30 - 2x

3x = 30

x = 10

So, E = -2 + 10 = 8

=========================================================================

2) E is 4/5 of the distance from F to D

So, the distance from F = 4/5 * 15 = 12

So, E = 13 - 12 = 1

=====================================================================

3) the ratio of DE : EF = 2 : 3

So,

3x = 2 ( 15 - x)

3x = 30 - 2x

5x = 30

x = 30/5 = 6

E = -2 + 6 = 4

=================================================

4) E is 1/3 of the distance from D to F

So, the distance DE = 1/3 * 15 = 5

So, E = -2 + 5 = 3

=====================================================

As a summery:

1) E = 8

2) E = 1

3) E = 4

4) E = 3

To find the solution of the system by graphing we need to plot each line in the plane and look for the intersection.

First we need to write both equations in terms of y:

now we need to find two points for each of this lines. To do this we give values to the variable x and find y.

For the equation 2x-y=-1, if x=0 then:

so we have the point (0,1).

If x=1, then:

so we have the point (1,3).

Now we plot this points on the plane and join them with a straight line.

Now we look for two points of the second equation.

If x=0, then:

so we have the point (0,-3)

If x=1, then:

so we have the point (1,-1).

We plot the points and join them wiith a line, then we have:

once we have both lines in the plane we look for the intersection. In this case we notice that the lines are parallel; this means that they wont intersect.

Therefore the system of equations has no solutions.

Solution

- The first integral is bounded by the x-values of [6, 22]

- The second integral is bounded by the x-values of [6, 14]

- When we are asked to find the difference between the two integrals, since, they both begin at 6, it implies that, when the second integral is taken away from the first integral, there must be some extra x-values.

- The extra values are from 14 to 22.

- Thus, we have:

Final Answer

The initial price is $38.21, and it got an increase of 7%, so the new price is the old one multiplied by 1.07:

Then, the new price decreased by 7%, so let's multiply it by 0.93 (that is, 1 minus 0.07):

So the price in August is $38.02.

What is area of rectangle?

Rectangle is a four sided figure whose parallel sides are equal and whose every angle is 90°

The total space taken by the rectangle is called area of the rectangle.

If the length of the rectangle be l and the breadth of the rectangle be b, then area of the rectangle is given by

Area = [tex]l \times b[/tex]

Here,

Length of classroom = [tex]6\frac{4}{5}[/tex] m = [tex]\frac{34}{5}[/tex] m

Width of classroom = [tex]1\frac{3}{8}[/tex] m = [tex]\frac{11}{8}[/tex] m

Area of classroom = [tex]\frac{34}{5} \times \frac{11}{8}[/tex]

                               = [tex]\frac{187}{40}[/tex]

                               = [tex]4\frac{27}{40}[/tex] [tex]m^2[/tex]

Step 2: Apply the subtraction rule of logarithm given as

Thus, we have:

Therefore, the correct answer is:

The x intercept is the value of x when y = 0

Given that x intercept = - 1, the coordinate is (- 1, - 0)

The y intercept is the value of y when x = 0

Given that y intercept = - 2, the coordinate is (0, - 2)

Slope = (y2 - y1)/(x2 - x1)

x1 = - 1, y1 = 0

x2 = 0, y2 = - 2

Slope = (- 2 - 0)/(0 - - 1)

slope = - 2/1

slope = - 2

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:

y = kx

for some constant k , called the constant of proportionality . This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

The unitary method is a technique used to determine the value of a single unit from the value of many units and the value of multiple units from the value of a single unit. We typically utilize it for math calculations. This approach will come in handy for topics involving ratio and proportion, algebra, geometry, etc. In the unitary technique, we always count the value of a unit or one quantity first before figuring out the values of more or fewer quantities. This method is referred to as the "unitary method" for this purpose.

There are two types of unitary methods because they result in two types of variations and those are given below:

Here, m is the slope of the line and c is the y intercept.

Comparing the above equation with the given equation of a line y=-5x+2, we get

Problem

Determine the functions value when x= -1?

a. g(-1) = -3

b. g(-1) = 0

c. g(-1) = 1

d. g(-1) = 27​

Solution

For this case we just need to find the value of g when x= -1 and if we look at the table we got:

g(-1)= (-1)^3 + 6(-1)^2 +12(-1) +8

g(-1)= -1 +6 -12+8 = 5-12+8= 1

And then the solution for this case would be:

c. g(-1) = 1

Step 1 : Let's review the information given to us to answer the problem correctly:

• Annual salary of the governor of New York = $ 1,790,000

• Annual salary of the governor of Tennessee = $ 940,000

Step 2: Let x to represent the annual salary of the governor of New York

and let's find the ratio of the salary of the governor of Tennessee, as follows:

940,000/1,790,000 = 0.525

Step 3: Now, let's write the equation for calculating the salary of the governor of Tennessee for any given year, this way:

• 0.525x = Annual salary of the governor of Tennessee

•

Step 4: If the salary of the governor of New York for the next year is 2,000,000, then we can calculate the salary of the governor of Tennessee, this way:

0.525x = 0.525 * 2,000,000 = 1,050,000

The annual salary of the governor of Tennessee woudl be 1,050,000

This is the term that is used to refer to the angle that lies between the horizontal line and the object that would be observed from the horizontal line.

In the question we have the following data

b = 250 feet

angles = 31 degrees, 29 degrees

for the top α = 31 degrees, β = 59

For the bottom α = 29 degrees, β = 61 degrees

We have the formula as

a /sin α = b / sin β = c

tan ∅ = opp / adj

for ΔOCA

h1 = 250 x tan 39 degrees

= 250 x 0.8098

= 202.45

h2 = OCB

= 250 x tan 23

= 250 x 0.4245
