Subtract x from both sides
you get 6x = 12
divide the 12 by 6
you get 2.
Answer:
x = 2
Step-by-step explanation:
4 - 7x = x - 12
+7x +7x
4 = 8x - 12
+12 +12
16 = 8x
16/8 = x
2 = x

================================================
Work Shown:
We'll use the tangent rule since it connects the opposite and adjacent side.
tan(angle) = opposite/adjacent
tan(42) = x/20
20*tan(42) = x
x = 20*tan(42)
x = 18.00808
x = 18
The value is approximate.
Rounding 18.00808 to the nearest tenth leads to 18.0 which is the same as 18

Determine whether the set is well defined.
1) The set of manufacturers of televisions that enjoyed sizeable profits in 1996
A) not well defined
B) well defined
Answers
Answer:
A) not well defined
Step-by-step explanation:
A set is said to be a well-defined set when we can clearly state whether something belongs to that set or not without any trace of ambiguity.
This implies that based on the information provided, we can easily decide on the members of a well defined set. A set that is not well defined carries some level of ambiguity regarding what and what should be part of the set.
In this case, 'sizeable profits' was not clearly defined. There ought to have been a threshold of profit defined as sizeable (e.g profit of $ 1,200,000 and above).
Since there is no such definition of 'sizeable profits', the set is not well defined.

Step-by-step explanation:
you use the rise over run formula. as you can see, the line hits certain points. You count how many points it is above and over, and that is 2 over 1. Remember, lines always go from left to right, so if it goes diagonal downward, it's a negative slope.
Karmen wants to purchase a pair of jeans with an
original price of $35.00. The jeans are on sale for 30%
off and she had a coupon for $2.00 off any purchase.
Her mom wants her to determine the actual price
before they go to the store.
How much money would she save?
Answers
Answer:
Ok, this is complicated. First you multiply 35 by .30. This gets you $10.50 OFF of the original price. Ok? So then you add the 2 dollar coupon. This gets you $12.50 OFF. So she would save $12.50.

Plz help me !!!! 50 points to whoever answers it correctly. Let the graph of g be a vertical stretch by a factor of 4 and a reflection in the x-axis of the graph of f(x)=x^2-3. Write the equation for g.
Answers
Answer:
So there are two answers.
Step-by-step explanation:
One answer is vertical strech which streches it vertically and that equation would be f(x)= -4x^2+3 (this is also reflected across the x-axis)
The other answer is if you want a vertical compression and that equation would be f(x)= -1/4x^2+3 (also reflected across the x-axis)

Write the equation of a line that is parallel to y=-7x+5 and which passes through the point (-1, -6).
Answers
Answer:
y = -7x - 13
Step-by-step explanation:
When graphing a great website to use is desmos graphing calculator. In it I put in the equation you gave me and the point (-1,-6). When making a parallel equation it should have the same slope as the original problem, so -7. I then set up the equation for y = -7x, since that is what the know and put in numbers to the y-intercept till it matched up with the dot. Making the equation y = -7x - 13

What is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the
point (15,-5)?
O y=x-20
O y=-3x+20
0 v= 2 X-20
O y=-3x+20
Answers
Answer: y=-5/3x+20 or y=-1 2/3x+20, so 20.
Step-by-step explanation: Actually, neither one of those options are correct. You may recall that the slope of the perpendicular line would be the exact opposite, the reciprocal, of the given line. The exact opposite of 3/5x is -5/3x, which could be reduced to -1.5x. From there, you could substitute x and y, which are 15 and -5 in this case, into the y=mx+b equation:
-5=-5/3(15)+b *b is y-intercept*
-5=-25+b Multiplied -5/3 by 15 first
-20=b Subtracted -25 from both sides (it'd be --25, so
basically just +25)
20=b Reciprocate b because you need the opposite
Hope this helps,

It is assumed that the test results for a class follow a normal distribution with a mean of 78 and a standard deviation of 36. If you know that a student's grade is greater than 72, what is the probability that it is greater than 84
Answers
Answer: 0.4337
Step-by-step explanation:
Let X represents the test results for a class that follow a normal distribution .
Given: Mean [tex]\mu=78[/tex], Standard deviation [tex]\sigma=36[/tex]
Then, the probability that it is greater than 84 will be
[tex]P(X>84)=P(\dfrac{X-\mu}{\sigma}>\dfrac{84-78}{36})\\\\=P(Z>0.167)\ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<0.167)\\\\=1-0.5663=0.4337\ [\text{By p-value table}][/tex]
Hence, the required probability = 0.4337

You’d divide the candy by 7 to get the seven parts, then multiply by two to calculate how much candy his friend got
9821/7= 1403 pieces of candy per part

Jane lose 4.7 miles from the local ice cream parlor wow Sarah lives only 3.4 miles from the same ice cream parlor how many more feet away from the parlor does Jane live? Explain how you got the answer.
Answers
9514 1404 393
Answer:
6864 ft
Step-by-step explanation:
In miles, the difference of distances is ...
4.7 mi - 3.4 mi = 1.3 mi
We know there are 5280 feet per mile. In feet, that distance is ...
(1.3 mi)×(5280 ft)/(1 mi) = (1.3×5280) ft = 6864 ft
Jane lives 6864 feet farther from the parlor than Sarah.
