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
A. x = -3 is the answer :)

OMG this question is so weird but please take it seriously. Working together, Tom and Di ck can dig 3 holes in 6 hours. Knowing Tom digs twice as fast as Di ck, how many hours would it take Tom, working alone, to dig 12 holes?
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.

Danielle wants to paint her daughters room pink. She has two different plans: Plan A: Use 5 parts white and 2 parts red. Plan B: Use four parts white and 1 part red.
If "Danielle" needs a total of 3 gallons of paint, how much will need to be red and how much will need to be white to make the least red mix? Use the mix that you selected from part A. (DOK 3)
Answer:
If we are assuming that plan A produces a whole gallon then you would need 15 parts white and 6 parts red

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?
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.
what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Answer:
x+y=5
Step-by-step explanation:
y=-x+5
add x to both sides
x+y=5
Answer:
x + y = 5
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - x + 5 ( add x to both sides )
x + y = 5 ← in standard form

what is the closest to 1/2 + 1/3?
Answer:
C) 0.8
Step-by-step explanation:
First, we have to get both numbers to the same denominator (LCD). So we multiply 1/2 by 3/3 to get 3/6 and 1/3 by 2/2 to get 2/6. When we add them, we get 5/6, which in decimal form is .83333333, which is closest to C. 0.8

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

Please answer: is y = 4x - 9 a function?
Answer:
Yes.
Step-by-step explanation:
Yes.
y = 4x - 9 is the equation of a line with slope 4and y-intercept -9.
All non-vertical lines are functions.
Since a line with slope 4 is not a vertical line, this relation is a function.

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?
Answer:
400 L of orange punchStep-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
