Answer: The coordinates of the midpoint (1.5, -0.5)

Step-by-step explanation:

For the x-coordinate, find the difference between -1 and 4. That's 5. Take half of 5 and add to -1. So -1+2.5= 1.5

For the y-coordinate, the difference between -6 and 5 is 11. Half of 11 is 5.5. Add -6 + 5.5= 0.5

Answer: Subtraction property of equality.

Step-by-step explanation:

n + 9 = -3

You are trying to move 9 from one side to the other. To do that, you have to do the inverse operation and subtract nine from both sides. Your result would be n = -12.

Answer:

-35

Step-by-step explanation:

I don't know what you are talking about but this is my method ;

[tex]-20 + - 15[/tex]

It is best written as;

[tex]-20+(-15)\\\mathrm{Remove\:parentheses}:+\times - = -\\-20-15[/tex]

Note ; the bracet means multiply so + multiplied by -15

[tex]\mathrm{Subtract\:the\:numbers:}\:-20-15\\=-35[/tex]

according to the table which were there is a local minima of the function f (x)?(0 9)

Answer: 15 square yards of carpeting.

Hope this helps!

Pretty sure i'm wrong on this one but I can't figure it out either.

Sorry if I wasted your time.

Angela must purchase 29.7 square yards of carpeting.

Multiply the area by the conversion ratio to convert a square foot measurement to a square yard measurement. Because one square foot equals 0.11 square yards, you may use the following easy formula to convert:

square inches = square feet × 0.11

The area in square inches is equal to the square feet multiplied by 0.11.

The dimensions of her living room are 15 feet by 18 feet.

The area in square feet is :

15 × 18 = 270 sq ft

Now, the area in square yards is :

270 × 0.11 = 29.7 sq yds

Thus, she must purchase 29.7 square yards of carpeting.

Answer: -1

Step-by-step explanation:

3( x +7 ) =18

8Use distributive property

3x + 21 = 18

Substract 21 from both sides

3x = -3

Divide 3 by both sides

x = -1

Another way to solve:

3( x +7 ) =18

Divide 3 by both sides

x + 7 = 6

Substract 7 by both sides

x = -1

Answer:

x = -1

Step-by-step explanation:

In order to answer this question, all we have to do is simplify the equation:

3(x + 7) = 18

3x + 21 = 18

-21 -21

3x = -3

/3 /3

x = -1

You can even put this answer in the equation to check.

Step-by-step explanation:

4 2/3= 12/3+2/3=14/3

3 2/1=7/2 but you have to flip it

so you end up with 14/3*2/7

4 2/3 = 14 / 3

3 1/2 = 7/2

An easy way to divide fractions is to find the reciprocal of the second fraction.

The reciprocal of 7/2 = 2/7

Then we multiply straight across.

14/3 × 2/7

I believe the independent would be the BIC pen and dependant would be the Papermate blue

The controlled variable would be the two pens because there is no way to change which one lasts longer except maybe adding more ink.

Answer:

-7/24 = r

Step-by-step explanation:

3/8 = r + 2/3

Subtract 2/3 from each side

3/8-2/3 = r + 2/3-2/3

3/8 - 2/3 = r

Get a common denominator or 24

3/8 *3/3    - 2/3 *8/8    =r

9/24   - 16/24   =r

Answer:

15(b+2) + 15 + 2b-9 +b = 90

Step-by-step explanation:

Essentially you add up all of the values and make it equal to 90, then solve for b

15(b+2) + 15 + 2b-9 +b = 90

15b + 30 + 15 + 2b - 9 + b = 90  

18b + 30 + 15 - 9 = 90

18b + 36 = 90

18b = 54

ANSWER

M=(−72,12).

Step-by-step explanation:

The midpoint for two points P=(x1,y1) and Q=(x2,y2) is

M=(x1+x22,y1+y22).

We have that x1=−3, y1=−1, x2=−4, y2=2.

So, M=(−3+(−4)2,−1+(2)2)=(−72,12)

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(−3,−1) and (−4,2)

The midpoint is

[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]
