Hey sorry to bother but i need this done as fast as possible. "Solve the system without graphing. Explain in steps. 3x=8+y, 4x-3y=1

Answers

Answer 1

Isolate y
3x-8= y
Let x = 0
3(0)-8 = y
y= -8

Isolate x
4x-3y=1
4x=1+3y
Let y= 0
4x = 1+ 3(0)
4x= 1
Divide both sides by 4
x= 1/4

eqn of line

5x-y=-9

Step-by-step explanation:

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line

The number of cookies Natalie can bake varies directly with the time she
spends baking. She can make 3 dozen cookies in 0.5 of an hour. How many
dozen cookies can she make in 5 hours?

Please help fast!!

Answers

We already know that 0.5 of an hour, or half of an hour, is 30 minutes. We also know that 3 dozen equals 36. With this information, we can conclude that Natalie can make 72 cookies in one hour. 72 times 5 is 360. 360 divided by 12 is 30, so, Natalie can bake 30 dozen, or 360, cookies in five hours.

the answer would be 10 dozen cookies

8 more than 2 times a number is 29.

Answers

the answer is 10.5 because the equation is 2x+8=29

Answer:

X = 21/2 = 10 1/2 or 10.5

Step-by-step explanation:

2x + 8:= 29

-8. -8

2x. = 21

divde both sides by 2

x = 21/2 = 10 1/2

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.

y = 3x −24y = 3x −24

y = 3x + 24

y = -3x + 24

y = -3x - 24

Answers

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

4(3+2x) + 2 = 46 , solve for x I need help I'm a bit confused

Answers

Answer:

x=4

Step-by-step explanation:

4(3+2x)+2=46

12+8x+2=46

12+8x=44

8x=32

x=4

Answer:

Step-by-step explanation:

You need to start with the 2x inside the parenthesis

If you put 4 in place of x you get 8

8+3=11

then because there isnt any sign between 4 and the parenthesis you multiply

4x11=44

then its easy

44+2=46

Ill give brainliest immediately!!!! ^^^^^^^^ Uendre SEO 8. Read the text, then answer the question that follows: wild animals as viewed from a mountain camp-Camille Grant, October 2011 Through my binoculars, I viewed a group of wild animals in action. A pride of lions was sleeping when a small, yellow bus pulled up beside them. Tourists on a safari were packed into the bus like sardines in a can. Armed with cameras, they invaded the lions' territory, hoping to capture the perfect photograph. The crowd leaned out the windows, hooting and hollering, until the lions awoke. When the lions moved away, the bus rolled after them, relentlessly stalking the pride. One of the lions turned and roared to protect the young. This was greeted with cheers and a celebratory honk of the bus horn. The curious visitors observed the lions' routine for an hour before moving on. Leaving a cloud of dust, the bus headed away, taking the wild animals off to disturb someone else's home.

Many students define paragraphs in terms of length: a paragraph is a group of at least five sentences, a paragraph is half a page long, etc. In reality, though, the unity and coherence of ideas among sentences is what constitutes a paragraph. A paragraph is defined as a group of sentences or a single sentence that forms a unit (Lunsford and Connors 116). Length and appearance do not determine whether a section in a paper is a paragraph. For instance, in some styles of writing, particularly journalistic styles, a paragraph can be just one sentence long. Ultimately, a paragraph is a sentence or group of sentences that support one main idea. In this handout, we will refer to this as the controlling idea, because it controls what happens in the rest of the paragraph. which coordinate is a solution for the system containing the equations y=x+3 and y=4x?
