Answer:

1.)13x = +9

2.)9x = -5

so first you take 1^2 power and it would be 1 so then u add the 1x on to the 12x or 8x from whatever equation ur working on and u would get 13 x or 9x from there u need to get the x isolated from the number without an x so if ur doing number 1 you would do +9 on both sides which would clear the -9 on the left side and add 9 on the right making it 13x = 9

the length of a rectangle is 5 more than twice the width. if the perimeter of the rectangle is 76 meters, find the dimensions of the rectangle and choose the equation that represents the perimeter:

1. 76=2w+5
2. 76=2w+2(2w+5)
3. 76=w+2w+5
4. 76=2w+(2w+5)

Answers

Answer:

Dimensions: 11 meters by 27 meters

2. [tex]76=2w+2(2w+5)[/tex]

Step-by-step explanation:

Finding Dimensions:

The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.

With this information we can write:

Length = [tex]2w+5[/tex]

[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)

[tex]4w+10+2w=76[/tex]

[tex]6w=66[/tex]

[tex]w=11[/tex]

Length = [tex]2(11)+5[/tex]

Length = [tex]27[/tex]

∴ The dimensions of the rectangle is 11 meters by 27 meters.

Perimeter

Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]

(if there is no explanation, there will be no credit given) PLEASE I NEED FAST ILL GIVE BRAINLIEST

Answers

Answer:

1) C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) Continuous

Step-by-step explanation:

1) The given parameters are;

The base fee charged = $25

The amount charged for labor = $40/hour

The total cost for h number of hours is C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) The situation is continuous because the different input values of h can be infinite (from o to infinity)

Can u help me pls
I don”t know what to do

Answers

Answer:

Step-by-step explanation:

Do you know SOHCAHTOA

Sin = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

#1

We have to find cos(x) = adjacent/hypotenuse

[tex]cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}[/tex]

#2:

We are given an angle of 30 degrees and an opposite side of 15

We need to find the adjacent side, so we can use Tangent

[tex]tan(30) = \frac{15}{adj}[/tex]

[tex]adj = \frac{15}{tan(30)} = 25.98 = 26[/tex]

#3

We are given an angle and an opposite side and we have to solve for hypotenuse.

We can use sin

[tex]sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5[/tex]

#4:

We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent ([tex]tan^-1(x)[/tex], but not 1/tan(x))

[tex]tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759[/tex]

#5

We are given an opposite side and the hypotenuse, we can use sin

[tex]sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43[/tex]

If two sides and the angle that is not between them of one triangle are congruent to the corresponding two sides and the angle that is not between them of another triangle, then the congruency of those triangles cannot be determined.

Answers

Answer:

True

Step-by-step explanation:

The given parameters are;

Two triangles each with known measures of two sides of the triangle and a non included angle

Therefore, with the given information, each of the the triangles are undefined because the sides can be opened wider or narrowed to have two possible solutions, in the same manner a compass, having one leg at a fixed inclination to the drawing paper can have the second leg either come closer or go further than 90 degrees while the inclination of the one (first) leg remains the same.

Step-by-step explanation:

The x-intercept of a line is when it's y coordinate is 0, so input 0 into the equation for y and solve for x.

4x + 9(0) = 27

4x = 27  

 x= 6.75

Convert the following:(a) 300 cm into metre Civil DisobediencePart 1Most people remember Gandhi and Dr. Martin Luther King, Jr. as reformers who practiced non-violent forms of protest and advocacy. Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond.Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden.Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf.It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.Read this line from the third paragraph:For these and other reasons, Thoreau refused to pay his poll tax for a number of years.How does this sentence prepare readers for the final line of the paragraph? It lets readers know his refusal to pay wasn't just a passing idea. It lets readers know Thoreau was a thoughtful man. It tells readers his reasons for refusal were not important. It tells readers why Thoreau was not arrested for so long. The pedigree below traces the inheritance of alkaptonuria, a biochemical disorder.
