a line passes through the point(-4,-6) and has a slope of 1/2 What is the
equation of the line?

Answers

Answer:

x-2y-8=0

Step-by-step explanation:

The equation of line is given by the relation

y-y1=m(x-x1)

where m is the slope

now, given x1=-4 and y1=-6 and the slope is 1/2.

substitute into the equation to get

y+6=1/2(x+4)

multiplying through with the L.C.M

which is 2

2(y+6)=1/2×2(x+4)

2y+12=x+4

making x the subject

x= 2y+8 hence the equation of the line is x-2y-8 =0

Final answer:

The equation of the line that passes through the point (-4, -6) with a slope of 1/2 is y = 1/2x - 4.

Explanation:

To find the equation of a line that passes through the point (-4, -6) with a slope of 1/2, we use the point-slope form of a line's equation which is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. In this case, the point is (-4, -6) and the slope m is 1/2.

Plugging in the values, we get:

y - (-6) = (1/2)(x - (-4))

Simplify the equation:

y + 6 = 1/2x + 2

To get the equation in slope-intercept form y = mx + b, we do:

y = 1/2x + 2 - 6

y = 1/2x - 4

So the equation of the line is y = 1/2x - 4.

Question 8 -
Cindy worked for 15 consecutive days, earning an average wage of $91 per day. During the first 7
days her average was $87/day, and her average wage during the last 7 days was $93/day. What was
her wage on the Sth day?
a
b.
$83
$92
c.
d
$97
$105

Answers

Answer:

Her wage on the 8th day is $105 ⇒ answer d

Step-by-step explanation:

* Lets explain how to solve the problem

- The average of set of data = The sum of data/the number of data

- The sum of data = the average of set of data × the number of data

∵ Cindy worked for 15 consecutive days

∵ She is earning an average wage of $91 per day

∴ Her total earning = 91 × 15 = $1365

∵ Her average earning during the first 7 days is $87 per day

∴ Her total earning in the first 7 days = 87 × 7 = $609

∵ Her average earning during the last 7 days is $93 per day

∴ Her total earning in the last 7 days = 93 × 7 = $651

- Her total earning in the 14 days is the sum of the earning in the

 first 7 days and the earning during the last 7 days

∵ Her total earning in the 14 days = 609 + 651 = $1260

∵ Her total earning in the 15 days is $1365

- To find her wage on the 8th day subtract her wage of the 14 days

  from her wage of the 15 days

∴ Her wage on the 8th day = 1365 - 1260 = $105

* Her wage on the 8th day is $105

Change .06 to a percent

Answers

Answer:

6 percent

Step-by-step explanation:

if the 6 was in the tenths place (1 to the left) it would be 60%, however it is in the hundreds place therefore its value is 6%

Final answer:

To convert 0.06 to a percent, multiply it by 100 to get 6%.

Explanation:

To change 0.06 to a percent, you multiply it by 100. Doing this moves the decimal point two places to the right.

Here's the step-by-step calculation:

Start with the decimal: 0.06

Multiply by 100: 0.06 × 100 = 6

The result is: 6%

So, 0.06 as a percent is 6%.

Answers

2x + 2 = 22
2x = 20
X = 10

Answer:

x = 10

Step-by-step explanation:

First you need to add like terms (x + x), which would give you 2x.

2x + 2 = 22

Then subtract 2 from both sides, causing it to cancel out one side, and 22 - 2, on the other side:

2x + 2 = 22

      -2     -2

22 - 2 is 20, giving you:

2x = 20

Then divide both sides by 2:

2x/2 = 20/2

And you should get x = 10 as your answer.

The volume of a box of earrings is 216 cubic centimeters. What is the length of one edge of the box

Answers

Answer:

its 6

Step-by-step explanation:

because

6.6.6= 216

Answer:

6 centimeter is the length of one edge of the boxStep-by-step explanation:

Given  : The volume of a box of earrings is 216 cubic centimeters.

To find : What is the length of one edge of the box.

Solution : We have given

Volume of a cubic box = 216 cubic centimeter .

Volume of cube = (side)³ .

(side)³  = 216 cubic centimeter .

On taking cube root both sides.

side = [tex]\sqrt[3]{216}[/tex].

Side =  [tex]\sqrt[3]{6*6*6}[/tex].

Side=  6 centimeter .

Therefore, 6 centimeter is the length of one edge of the box.

Solve for n: -6(n -8) = 4(12 -5n) + 14n.​

Answers

Answer:

infinite solutions

Step-by-step explanation:

Given

- 6(n - 8) = 4(12 - 5n) + 14n ← distribute parenthesis on both sides

- 6n + 48 = 48 - 20n + 14n, that is

- 6n + 48 = 48 - 6n ( add 6n to both sides )

48 = 48 ← True

This indicates that the equation is true for any value of n

Answer:

This is a very classical type of equation in which, the solution is basically any number and it is known as an "Identity". So it has infinite solutions

Step-by-step explanation:

Apply the distributive law to both sides of the equation:

-6(n-8) = 4(12-5n)+14n

-6n-6*(-8) = 4*12+4*(-5n) + 14n

Reduce similar terms

-6n+48=48-20n+14n

-6n+48=48-6n

From here it is clear them to see that by adding -48 and 6n to both sides one obtains the identity 0 = 0

-6n+48=48-6n

-6n +6n + 48 -48 = 48 -48 - 6n + 6n

0 = 0

So every time you find this kind of problem and after reducen the equation you end up with a true statement, then the equation has infinite solutions

Elizabeth wants to join a health club for 8 months to get in shape for her wedding. Which club should she join? Either show work or explain why you chose that club.






Answers

A) Because the 80 is by itself that would be the start up fee.

B) We are told x is the number of months. Since the X is being multiplied by 30, we know that would be the total monthly cost. This is being added to the 80, which does not have an exponent, so we know this is a single cost, which would be the start up fee.

C) Copying the same format as the given equation above, change the numbers:

f(x) = 20 + 35x

D) I used the same format as the first equation, which meant replacing the start up cost from the original one ( 80) with the start up of the new one (20). Then I changed the monthly cost from the original one (30) with the monthly cost of the new one (35).

E) Replace x in each equation with 8 and calculate the cost of each:

80 + 30(8) = 80 + 240 = $320

20 + 35(8) = 20 + 280 = $300

The second club (club B) is the cheaper option for her.

Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum.

1/5+2/3

Answers

Answer: Find the lowest common denominator of the 2 denominators

Step-by-step explanation:

The common in both denominator is 15.

3: 3,6,9,12,15,18,21,24,27,30

5: 5,10,15,20,25.30,35,40,43,50

Since 5x3 is 15, 1/5 x 3/3= 3/15

Since 3x5 is 15, 2/3 x 5/5= 10/15

3/15 is equivalent to 1/5 and 10/15 is equivalent to 2/3.

3/15 + 10/15 is equal to 13/15

13/15 can't be simplified because they are both odd numbers and they have less than 2 factors.

Hope this helped! Have a nice day! :D  

Final answer:

To add 1/5 and 2/3, you must find the LCD, which is 15, convert the fractions to have the same denominators, then add them to get the sum of 13/15.

Explanation:

To add the unlike fractions 1/5 and 2/3, we first need to convert them to equivalent like fractions using their Least Common Denominator (LCD).

Prime factorize the denominators: 5 is already a prime number, and 3 is also a prime number.

To find the LCD, we take the product of the different prime factors, which is 5 × 3 = 15.

Convert each fraction by multiplying by an appropriate form of '1' to get the same denominator: 1/5 = (1×3)/(5×3) = 3/15 and 2/3 = (2×5)/(3×5) = 10/15.

With like denominators, we can now add the fractions: 3/15 + 10/15 = 13/15.

The final answer, 13/15, is already in its simplest form and cannot be reduced further.

Final answer:

The greatest common factor (GCF) of 150, 275, and 420 is 25. It is the highest number that can divide all three numbers without a remainder and is found by identifying the common prime factors among them.

Explanation:

The question is asking for the greatest common factor (GCF) of the numbers 150, 275, and 420. The GCF is the highest number that can divide all three numbers without leaving a remainder. To find the GCF, we can break down each number into its prime factors:

150 = 2 × 3 × 5 × 5275 = 5 × 5 × 11420 = 2 × 2 × 3 × 5 × 7

the common factors for 150, 275, and 420 are 5 × 5, since these are the only prime factors that appear in all three prime factorizations. Consequently, the GCF of 150, 275, and 420 is 5 × 5, which equals 25.

0.90(2.25d + 1.40t + 6).

What is the total cost for Lindy and her friends to order 4 drinks and a medium pizza with 3 toppings?

A.
$17.28
B.
$16.52
C.
$28.40
D.
$15.69

Answers

Answer:

A

Step-by-step explanation:

In the expression

[tex]0.90(2.25d+1.40t+6),[/tex]

d is the number of drinks Lindy orders;

t is the number of toppings Lindy orders.

If Lindy and her friends order 4 drinks and a medium pizza with 3 toppings, then d = 4 and t = 3. Find the value of the expression above when d = 4 and t = 3:

[tex]0.90(2.25\cdot 4+1.40\cdot 3+6)=0.90(9+4.20+6)=0.90\cdot 19.20=17.28[/tex]

So, Lindy and her friends will pay $17.28

Final answer:

Lindy's total cost for ordering 4 drinks and a pizza with 3 toppings amounts to $17.28, so the correct answer is Option A.

Explanation:

First, we substitute the given number of drinks and toppings into the expression, resulting in 0.90(2.25*4 + 1.40*3 + 6). That simplifies to 0.90(9 + 4.2 + 6), which further simplifies to 0.90(19.2). Finally, we multiply 0.90 by 19.2 to get the total cost, that is $17.28, which implies the correct answer is Option A.

Enter an inequality that represents the graph in the box.

Answers

Answer:

[tex]y>-3x+6[/tex]

Step-by-step explanation:

First find the equation of the "boundary line" that separates the two sections of the plane. It is very simple to find its slope_y-intercept form from the graph.

We can find the slope of the boundary line by examining the two points where it intersects the axes: It crosses the y-axis at (0,6) (0 for x, 6 units for y)

and also crosses the x axis at (2,0) (2 unites for x and 0 for y)

That means that from the y intersect crossing, in order to arrive at the x intersect crossing, one has to go:

2 units to the right (this is called "run")

and 6 units down (this is called "rise", but should be considered as a negative value because instead of "rising" is going down)

Therefore, the slope of the boundary line is: [tex]slope = \frac{rise}{run} = \frac{-6}{2} = -3[/tex]

We also see that the y-intercept is = 6 (the point at which the line crosses the y-axis.

Then, we can write the equation of the boundary line as:

[tex]y = -3 x + 6[/tex]

Now, the set of (x,y) points that are highlighted in the picture are those "ABOVE" the boundary line, that is those points where the y-value is greater than those defined by the boundary line. Since the boundary line is drawn with a dotted line, that indicates that those values corresponding to (x,y) values in the line itself should NOT be included.

We therefore arrive at an inequality that does not contain an equal sign (to preclude the actual (x,y) values in the line to be included). and which indicates that we want all the (x,y) points on the plane which have y-values greater than those define by the boundary line. That is:

[tex]y>-3x+6[/tex]

Final answer:

The expression 4 3/4 * 5/6 * -2 1/3 evaluates to -665/72 after converting mixed numbers to improper fractions and then multiplying the numerators and denominators. The result is in its simplest form.

Explanation:

The question involves evaluating a mathematical expression with mixed numbers and fractions and writing the answer in its simplest form. To solve this, we first convert mixed numbers to improper fractions. The expression given is 4 3/4 * 5/6 * -2 1/3. First, convert the mixed numbers:

4 3/4 = 4 + 3/4 = (4*4+3)/4 = 19/4-2 1/3 = -2 - 1/3 = (-2*3-1)/3 = -7/3

Now multiply the improper fractions:

(19/4) * (5/6) * (-7/3)

Multiply the numerators: 19 * 5 * (-7) = -665
Multiply the denominators: 4 * 6 * 3 = 72
Therefore, the result is -665/72. This is already in its simplest form as the numerator and denominator have no common factors.
