What is the solution for the equation? 3x + 15 -7x = 27

A. x = -3
B. x = 1.2
C. x = 3
D. x= -10.5

Answers

Answer 1

Answer:

A. x = -3

Step-by-step explanation:

add the "x"s together

-4x + 15 = 27

subtract 15 from both sides

-4x = 12

divide both sides by -4

x = -3

Answer 2

A. x = -3 is the answer :)

Answers

Answer:

Tom can dig 12 holes in 36 hours.

Step-by-step explanation:

Tom and Di ck dig 3 holes in 6 hours.

Tom works twice as fast as Di ck, so it is as if Tom is the same as 2 people at Di cks's speed and Di ck is as if it is 1 person at Di ck's speed. This means it is as if there are 3 people working at Di ck's speed.

Di ck working alone can dig 1 hole is 6 hours.

Tom can dig 2 holes in 6 hours.

Tom can dig 12 holes in 36 hours.

Shari takes violin lessons. The equation

288x – 4y = –192 relates y, the total cost of the

lessons, and x, the number of lessons. Shari

incorrectly states that the y-intercept is –192. why did shari think that -192 was the y-intercept?

Answers

Answer:

if [tex]-192[/tex] is not divided by [tex]-4[/tex], then y - intercept becomes [tex]-192[/tex].

In such a situation, Shari thought that -192 was the y-intercept.

Step-by-step explanation:

Given: [tex]288x-4y=-192[/tex]

Solution:

Consider the equation:

[tex]288x-4y=-192[/tex]

To find y-intercept, put [tex]x=0[/tex]

[tex]288(0)-4y=-192\\-4y=-192\\y=\frac{-192}{-4}\\y=48[/tex]

In the second step [tex]-4y=-192[/tex],

if [tex]-192[/tex] is not divided by [tex]-4[/tex], then y - intercept becomes [tex]-192[/tex].

In such a situation, Shari thought that -192 was the y-intercept.

How is the graph of y = |x| − 1 different from the parent function f(x) = |x|?

Answers

Answer:

Step-by-step explanation:

the graph moves down one unit

if you add/subtract outside the parent function the graph moves up/down

We can define transformations as operators that act over functions and modify them in some way. One of these transformations is the family of translations, who translate the whole graph of the function in some given direction.

Here we will find that the graph of y = |x| - 1 is a translation of 1 unit downwards of y = |x|.

To see this, we first need to know the vertical translation.

For a given function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N

If N is positive the translation is upwards

if N is negative the translation is downwards,

So if here we have:

f(x) = |x|

then:

g(x) = |x| - 1 = f(x) - 1

So we can see that this is a translation of one unit down. This moves the whole graph of |x| one unit downwards, the graphs can be seen in the image below.

Where the blue graph is the one of y = |x| - 1

An orange punch is 45% juice and a mango punch is 20% juice. By combining the two, a company is making 500 L of a fruit punch that is 40% juice. How many liters of orange punch are needed for the company's concoction?

Answers

Answer:

400 L of orange punch

Step-by-step explanation:

step one:

given data

orange punch is 45% juice and

mango punch is 20% juice.

amount of fruit punch to be made is

500 L of a fruit punch that is 40% juice.

Let x = the number of liters of orange punch in the fruit punch.

Then the number of liters of mango is 500 - x

The number of liters of orange + mango juice is

0.45x + 0.2(500 - x), and this must equal the number of liters

in the fruit punch, which is 0.4*500

0.45x + 100 - 0.2x = 200

solve for x

0.45x-0.2x+100-200=0

0.25x-100=0

0.25x = 100

x=100/0.25

x = 400 L

400 L of orange punch
