2/5k - 3 1/2. K= 15
EVALUATE

Answers

Answer 1
Exact form
K=-150\31

Answer 2

Answer:

Solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] and find value of k

Solving:

[tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex]

Convert mixed fraction into improper fraction

[tex]\frac{2}{5}K-\frac{7}{2}K =15[/tex]

Taking LCM of 5 and 2 we get 10

[tex]\frac{2*2K-7*5K}{10} =15\\\frac{4K-35K}{10} =15\\\frac{-31K}{10} =15[/tex]

Divide both sides by -31/10

[tex]\frac{-31K}{10}*\frac{-10}{31}=15* \frac{-10}{31}\\K=\frac{-150}{31} \\K=-4\frac{26}{31}[/tex]

So, solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]

Is this a cubic graph?
Is it a reflection of its parent graph?
This graph shifted _ by _ units

Answers

Answer:

we conclude that the given graph is a cubic function and is translated by shifting 2 units to the left.

Thus, the graph is shifted left by 2 units.

The graph of the parent function f(x)=x³ and f(x+2) = f(x+2)² is shown below.

Step-by-step explanation:

If we carefully analyze the given graph, it is clear that the given graph is the transformed image of form f(x+b) of parent cubic graph f(x) = x³.

In this graph, the function f(x) has been moved over 2 units to the left.

In order to shift a function 2 units to the left, we need to add '2' inside the function's input.

In other words,

f(x+2) = f(x+2)² means the function f(x) is shifted 2 units to the left.

Therefore, we conclude that the given graph is a cubic function and is translated by shifting 2 units to the left.

Thus, the graph is shifted left by 2 units.

The graph diagram of the parent function f(x)=x³ and f(x+2) = f(x+2)² is shown

16. IF X= 31, then what is the perimeter of triangle JMN?

Answers

Answer:

180

Step-by-step explanation:

To solve we must first plug 31 into each expression for x.

2(31)+5= 67

3(31)-9= 84

31-2= 29

Then, remember that the perimeter is the sum of all of the sides. So add all of the previous sums, 67+84+29. Therefore, the answer is 180.

How do you graph the equation...
y=6x+600

with a domain of 0 t 650 and a range of 0 d 1500

Answers

The first is in the form y=Mx+b where m is the slope and b is the y-intercept. Start at 600 on the y-axis and graph with a slope of six. The second is in the same form but the y-intercept is 0, so start at the origin and graph with a slope of 8. The last is in the form y=b+mx, so start at 1300 and graph with a slope of 3. Remember, slope is rise/run or (change in y)/(change in x). Since the domain and range start at 0 these graphs will only be in the first quadrant with an x limit of 650 and a y limit of 1500.

-6(8k+9c)-3 use c=2 and k=9

Answers

Answer:

-543

Step-by-step explanation:

For every value of k, you substitute 9 and for every value of c, you substitute 2

-6((8x(9)+ 9(2)) - 3

so order of operations says you should do what's in the parentheses first.

8 x 9= 72     and 9 x 2 = 18

so now you have -6 ( 72 + 18) -3

Finish the calculating inside the parentheses:   -6 (90) -3

and now multiply -6   and 90 before you subtract 3

-6 x 90 = -540

-540 - 3   = -543

Angles in a Circle

Let's review some concepts about angles in a circle.

The central angle is formed between two radii and its vertex lie at the center of the circle.

The inscribed angle is formed between two chords whose vertex lies on the circumference of a circle.

The measure of a central angle x formed by the same lines that define an inscribed angle y is:

x = 2y

Following the definitions and relations above, we find that:

The measure of the central angle 98° is double the inscribed angle 35°+mThe measure of the central angle n is double the inscribed angle m

The first statement leads to:

98 = 2 (35+m)

Dividing by 2:

49 = 35 + m

m = 49 - 35 = 14

m = 14°

The second statement leads to:

n = 2m = 28°

Thus: m=14°, n=28°

24 is 29% of what number? Round to the nearest tenth,

Step-by-step explanation:

24/.29

=82.75862

but you want it rounded so 82.8 is your answer

I hope this helps

Answer:

82.8

Step-by-step explanation:

Step 1: If 29% of a number is 24, then what is 100% of that number? Set up the equation.

24 over 29% = Y over 100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

29Y = 24 x 100

29Y = 2400

Y = 2400 over 100 = 82.76

If you round 82.76 to the nearest tenth you get 82.8.

Jay thinks of a prime number. The sum of its digits is one more than a square number. Write down one number jay could be thinking of.

Answers

Answer:

Jay could be thinking of 11  

Step-by-step explanation:

Prime numbers are the numbers that have two factors only, 1 and itself as

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, .................

All prime numbers can divide by 1 and itself only

∵ A number is a prime number

∵ The sum of its digits is 1 more a square number

The sum of its digits = 1 + x, where x is a square number

→ We will start with the first prime number of 2-digits

11 is a prime number

∵ The sum of its digits = 1 + 1 = 2

→ Substitute it in the equation above to find x

2 = 1 + x

→ Subtract 1 from both sides

∵ 2 - 1 = 1 - 1 + x

1 = x

1 is the square of 1

What is the direct variation equation if Y varies directly with X and Y equals negative 12 when X equal 6

Answers

Step-by-step explanation:

y = kx, where k is a real constant.

When x = 6, y = -12:

(-12) = (6)k

Therefore k = -2.

Hence y = -2x.

The direct variation of Y with X is Y = -2X.

What is an equation?

Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.

As per the given data:

Y varies directly with X.

Y equals -12 when X equal 6.

Let's consider the equation Y = kX:

∴ -12 = k(6)

k = -2

Y = -2X

Hence, the direct variation of Y with X is Y = -2X.

Answers

Given:

Initial pay rate = $8.50 per hour

Increase in pay rate = $0.75 per year

To find:

The equation that represents the relationship between years on the job and pay for hour.

Solution:

Let x be the number of years and y be the pay rate after x years.

According to the question,

Increase in pay rate in 1 year = $0.75

Increase in pay rate in x year = $0.75x

So, variable pay rate = $0.75x

Initial pay rate = $8.50

So, the total pay rate is

Total pay rate = Initial pay rate + Variable pay rate

[tex]y=8.50+0.75x[/tex]

Therefore, the required equation is [tex]y=8.50+0.75x[/tex].

Find the unknown side length of the rectangle is 3 2/3 and if the area is 11m2

Answers

Answer:

The width of the rectangle given is equal to 3m.

Step-by-step explanation:

In order to solve this question we need to know that the areas of the rectangle is equal to [tex]A_{rectangle} = (l)(w)[/tex], where "l" is length and "w" is width. So know in order to solve this question we would have to find out the unknown width by using area and the length of the triangle. Based on the formula I wrote down earlier we can understand the following.....

[tex]A_{rectangle} = (l)(w)[/tex]

[tex]\frac{A_{rectangle} }{l} = \frac{(l)(w)}{l}[/tex]

[tex]w = \frac{A_{rectangle} }{l}[/tex]

Just now we found out the formula that we can use to solve for the width when we know the area and the length of the rectangle. Now in order to get the answer we just have to plug in the values we know, and we get........

[tex]w = \frac{A_{rectangle} }{l}[/tex]

[tex]w = \frac{11m^{2} }{(3\frac{2}{3}m )}[/tex]
