The coordinate of point B will be (3, -8) for the given line segment.

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given the line segment, AB

If the M(2, -1) is the midpoint of A(1,6) and B(x,y)

Then,

(1 + x)/2 = 2 ⇒ x = 3

(6 + y)/2 = -1 ⇒ y = -8

So B(3, -8).

Hence "The coordinate of point B will be (3, -8) for the given line segment".

Answer:

B

Step-by-step explanation:

Here, we are to find the odds against drawing a purple or yellow marble.

Mathematically, the odds against drawing a particular marble color = 1 - the probability of drawing that particular marble color

probability of drawing a purple colored marble = number of purple colored marbles/total number of marbles

= 84/(84 + 42 + 21 + 14 + 7) = 84/168 = 1/2

So the odds against drawing a purple colored marble = 1 - 1/2 = 1/2

The odds against drawing a yellow marble color = 1 - probability of drawing a yellow colored marble

Probability of drawing a yellow colored marble = number of yellow marbles/total number of marbles = 14/168 = 1/12

So the probability of drawing a yellow colored marble or purple colored marble = 1/12 + 1/2 = 7/12

Now, the odds against drawing either of the two = 1 - the probability of drawing either of the 2 = 1 -7/12 = 5/12

or simply put 5 to 12

This can be written as -8 + (-10). Subtracting a positive is the same as adding a negative.

One way to think of negatives is to think of debt in money. Writing -8 means you are 8 dollars in debt. Add on 10 more dollars of debt and you'll be 8+10 = 18 dollars in debt total. So this is one way to see how -8-10 = -8+(-10) = -18.

Or you can think of it as if you are in a submarine. The number -8 could represent the idea you are 8 miles below sea level. Then if we subtract 10 from this, or add on -10, it means we're going down another 10 miles to get a total depth of 18 miles below sea level. At this point, we would write -18.

Answer:

D. [tex]\pi<x<2\pi[/tex]

Step-by-step explanation:

Given the function

[tex]y=cosx[/tex]

Kindly refer to the graph attached in the answer area.

Referring to the intervals [0, [tex]2\pi[/tex]].

It decreases from the interval [0, [tex]\pi[/tex]] and then starts increasing in the interval

[tex][\pi,2\pi][/tex].

Proving by taking derivative:

Taking derivative of the function, [tex]y=cosx[/tex]

[tex]\dfrac{dy}{dx}=-sinx[/tex]

In the interval [tex][\pi,2\pi][/tex], [tex]sinx[/tex] is negative i.e. [tex]sinx<0[/tex].

Therefore [tex]-sinx>0[/tex]

When, the derivative of a function is positive, then the function is strictly increasing.

So, the answer is:

D. [tex]\pi<x<2\pi[/tex]

Answer:

[tex]z = \frac{8}{5}[/tex]

Step-by-step explanation:

Calculate for the value of [tex]z[/tex] :

[tex]2(4z - 1) = 3(z + 2)[/tex]

-Use Distributive Property on both left and right:

[tex]2(4z - 1) = 3(z + 2)[/tex]

[tex]8z - 2 = 3z + 6[/tex]

-Take [tex]3z[/tex] and subtract [tex]8z[/tex] :

[tex]8z - 3z - 2 = 3z - 3z + 6[/tex]

[tex]5z - 2 = 6[/tex]

-Add [tex]2[/tex] to both sides:

[tex]5z - 2 + 2 = 6 + 2[/tex]

[tex]5z = 8[/tex]

-Take [tex]5z[/tex] and divide on both sides:

[tex]\frac{5z}{5} = \frac{8}{5}[/tex]

[tex]z = \frac{8}{5}[/tex]

Therefore, the value of [tex]z[/tex] is [tex]\frac{8}{5}[/tex].

The solution to the given equation is [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

The given equation is 2( 4z - 1) = 3(z+2).

To solve the given equation means we should determine the value of the variable z.

To solve this, we will first clear the brackets

[tex]2(4z - 1) = 3(z+2)[/tex]

Clearing the brackets

[tex]8z - 2 = 3z + 6[/tex]

Now, collect like terms

[tex]8z - 3z = 6 + 2[/tex]

Then,

[tex]5z = 8[/tex]

Now divide both sides by 5

[tex]\frac{5z}{5} = \frac{8}{5}[/tex]

∴ [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

Hence, the solution to the given equation is [tex]z = \frac{8}{5} \ or \ 1\frac{3}{5}[/tex]

Answer:

The maximum number of text messages you can send per month would be 41.

Step-by-step explanation:

1. First, you want to create an inequality from the word problem.  You know that $24.99 is a constant, so we won't put any variables next to it.  You also know that each text message is $0.12, so that would need a variable since it can change each month.  You also know that you can spend $30 maximum each month, so that goes on the other side of the inequality.  Your inequality will look like this:  0.12x+24.99≤30 (x is the number of text messages).

2. Second, you want to solve for x.  To do this, subtract 24.99 from each side.  After this, the equation is 0.12x≤5.01

3. Now, divide each side by 0.12.  Now your inequality is x≤41.75.  This represents how many text messages you can send per month without going over 30.

4. Finally, you have to realize that is impossible to send exactly 41.75 text messages.  So, you have to round down to 41 to get an even number of text messages, and that's your answer!

Hope this helps!  Feel free to ask any questions :)

I hope this helps

$7.20 will be Jennys total allowance.

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

Jenny has $2.40 deducted from her monthly allowance every time she forgets to do a chore.

If she forgets three times in a month.

Thus, Jennys total allowance will be

=2.40 x 3

=$7.20

Hence, $7.20 will be Jennys total allowance.
