Find the variation constant and an equation of variation for the given situation.
y varies directly as x, and y = 7 when x = 1/2.
Answer:
[tex]\displaystyle y=14\cdot x[/tex]
Step-by-step explanation:
Directly Proportion
It's said that y varies directly proportional as x, if:
[tex]y=k\cdot x[/tex]
Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:
[tex]\displaystyle 7=k\cdot \frac{1}{2}[/tex]
Solving for k:
k=14
Thus, the equation is:
[tex]\boxed{\displaystyle y=14\cdot x}[/tex]
Find the value of x.
55°
79°
110°
x°
Answer:
i think its 158
Step-by-step explanation:
i think what theyre doing here is a pattern because
79-55=24 and 110-79=31 which has no pattern but when u subtract 55 from 110 you get 110-55=55 so i just multiplied 79 by 2 getting the answer 158.
Solve using substitution
y = 4x + 11
2x – 5y = -1
Answer:
x=−3 and y=−1
Step-by-step explanation:
Substitute y=4x+11y=4x+11 into 2x-5y=-12x−5y=−1
-18x-55=-1−18x−55=−1
Solve for x in -18x-55=-1−18x−55=−1.
x=-3
Substitute x=-3x=−3 into y=4x+11y=4x+11.
y=-1
Answer:
28
Step-by-step explanation:
2x-5(4x+11)=-1
2x-20x+55=-1
-22x+55=-1
-22x+55-55=-1-55
-22x/-22=-56/-22
x=28

You bought 100 shares of stock at $15 per share. You sold your 100 shares at $21.75 per share. Calculate your total profit from the sale.
Answer:
$675
Step-by-step explanation:
You multiply 15 and 100 answer for that is 1500 then you multiply 21.75 and 100 answer for that is 2175 finally you subtract 1500 from 2175 witch gives you the final answer of 675
Total profit from the sale of 100 shares is equals to $675.
What is profit?
" Profit is the amount of money or revenue which we earned when selling price of a product is more than its cost price."
Formula used
Profit = Selling price - Cost price
According to the question,
Cost price of 1 share = $15
Therefore,
Cost price of 100 shares = 15 × 100
= $1500
Selling price of 1 share = $21.75
Selling price of 100 shares = 21.75 ×100
= $2175
Selling price > Cost price
Therefore , Profit
Substitute the value in the formula we get,
Profit = 2175 - 1500
= $675
Hence, total profit from the sale of 100 shares is equals to $675.

Answer:
negative
Step-by-step explanation:
okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.
Answer:
-4/3
Step-by-step explanation:
(-1 - 3)/(1 - -2)
use the slope formula (y2 - y1)/(x2 - x1)

what is the slope and y-intercept of y=4x+2
Answer:
slope: 4
y-intercept: 2
Step-by-step explanation:
We are given an equation, y = 4x + 2, and we are asked to find the slope and y-intercept of the line. Looking carefully, we can see that the equation is given to us in slope-intercept form.
Slope-intercept form is:
y = mx + b
where m is the slope and b is the by-intercept.
Knowing this, we can find that 4 is the slope of the line and 2 is the y-intercept.

3x - 4 + 6x = -31
17 = 3x - 10
2x + 6 = 4x - 8
17x - 5(3x - 11) = 41
5x - (3x - 6) = 18
6x - 3(4 - 5x) = 30
x - (-5) = 7
This is a lot of questions-
I did them all on a calculator.
1.)
3x - 4 + 6x = -31
3x + 6x - 4 = -31
9x - 4 = -31
9x = -27
Answer: x= -3
2.)
17 = 3x - 10
3x -10 = 17
-10 = -10
3x = 27
divide both sides by 3
Answer: x= 9
3.)
2x + 6 = 4x - 8
-6 = -6
2x = 4x -14
-4x (both sides)
-2x = -14
divide both sides by -2
Answer: x = 7
4.)
17x - 5(3x - 11) = 41
2x +55 = 41
-55 (both sides)
2x = -14
divide 2 both sides
Answer: x = -7
5.)
5x - (3x - 6) = 18
2x + 6 = 18
-6 both sides
2x = 12
divide both sides by 2
Answer: x = 6
6.)
6x - 3(4 - 5x) = 30
21 - 12 = 30
+12 boh sides
21x = 42
divide both sides by 21
Answer: x = 2
7.)
x - (-5) = 7
x + 5 = 7
-5 both sides
Answer: x = 2

(DOES NOT BELONG) Is Rational
(DOES NOT BELONG) Is not Irrational
(DOES NOT BELONG) Is not an integer
(DOES NOT BELONG) Not a Whole
(DOES NOT BELONG) Not Natural
Step-by-step explanation:
This is a fraction with a square root.
Fractions:
Are Not Whole (square root cancels this)
Are Rational BUT since this has a square root, it is not.
Are not natural
Are not integers (Whole numbers that ARE NOT fractions)
So basically from what I have learned, square root cancels literally everything.
Look at Data Set A

Identify whether this will be normal distribution or skewed left or right? (Hint: find the five number summary and make a box plot)
O skewed left
O skewed right
O normal distribution
The distribution of set A is a normal distribution
The data in set A is given as:
1 3 3 2 4 0 4 3 3 5 2
Represent the dataset as a plot, as follows
0
1
2 2
3 3 3 3
4 4
5
Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5
This implies that it follows a bell curve.
When a distribution follows a bell curve, such data is a normal distribution.
Hence, the distribution is a normal distribution
