Answer:

The coordinates of the midpoint are (-2,-1)

Step-by-step explanation:

The Midpoint of a Segment

Given a segment defined by points (x1,y1) and (x2,y2), the coordinates of the midpoint (xm,ym) are calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

We have the endpoints (0,4) and (-4,-6):

[tex]\displaystyle x_m=\frac{0-4}{2}[/tex]

[tex]\displaystyle x_m=\frac{-4}{2}=-2[/tex]

[tex]\displaystyle y_m=\frac{4-6}{2}[/tex]

[tex]\displaystyle y_m=\frac{-2}{2}=-1[/tex]

The coordinates of the midpoint are (-2,-1)

Answer:

It is incorrect because -3 is less than 0

Step-by-step explanation:

Say we have a number line that is- uhm

-5 to five so he numbers would look somewhat like

-5 -4 -3 -2 -1 0 1 2 3 4 5

(lesser to greater)

if you take -3>1-1 and simplify 1-1

you would now have -3>0

this statement says -3 is greater than 0

if you look on our number line which goes from lesser to greater then you see that -3 is less than 0 therefore -3>1-1 is incorrect.

Answer:

1 - 2n > 5. The solution set is (-∞, -2)

Step-by-step explanation:

e are dealing here with two problems:

First, to determine which mathematical statement represents "One less than twice a number is no less than five".

Second, solve n, that is, the solution set for the numbers that solve the inequality.

First Part: Identifying the inequality

"One less than twice a number" can be written as  , where n is the unknown number.

If it is not less than five, thus it is greater (no less) than five. Then, the symbol here is  " > " (greater).

As a result: "One less than twice a number is no less than five" could be rewritten as "One less than twice a number is greater than five", or:

.

Second Part: Finding the solution set

The solution set for this inequality is as follows:

⇒

Subtract -1 from each member of the inequality:

⇒  ⇒  

Multiply each member of the inequality by  (or divide each member by -2). We have to remember here that when we multiply or divide an inequality by a negative number (-n), this inverts the inequality, that is:

The solution set is then , which is any value less than -2 (not including -2, because is < and not ≤), and we have infinite negative numbers with such a characteristic. We can write it mathematically as an interval notation:

Solution set for  is .

Answer:

f(x) = 7

Step-by-step explanation:

we use the bottom equation (4x+3) because

1 > 0

so

4(1) +3 = 7

Answer and Step-by-step explanation:

Ok, so all we have to do is input the values into the equation.

We are told Adam bought 2 mechanical pencils and 8 spiral notebooks, which cost $13

and that

Kia bought 3 mechanical pencils and 5 spiral notebooks, which cost $12.50.

Adam: 2p + 8n = 13

Kia:     3p + 5n = 12.5

This is the answer.

#teamtrees #WAP (Water And Plant)

Answer: Adam: 2p + 8n = 13

Kia:     3p + 5n = 12.5

Step-by-step explanation:

Answer: Well... this is a long question.

1. All are moving 7 units to the left.

2. A = 0, B = 1 east, C = 1 east and 8 south, D = 8 south.

3. A = 0, B = 26 east, C = 26 east and 8 south, 8 east and 8 south.

Jessie runs 2 lap

Step-by-step explanation:

Given:

1 lap = 1 miles

Jessie runs = 2 miles

Find:

Number of lap Jessie runs

Computation:

Given that; 1 lap = 1 miles

So,

1 miles = 1 lap

And

2 miles = 2 lap

So,

Jessie runs 2 lap

Answer:

The nearest degree of the angle between the 8cm and 9cm sides is:

Step-by-step explanation:

To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.

From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.

Answer:

d < 7

Step-by-step explanation:

d + 12 < 19

1. Subtract 12 from both sides

d + 12 - 12 < 19 - 12

d < 7

Answer:

The regular costs 11 dollars each while the deluxe cost 23 each.

Step-by-step explanation:

You need to setup two equations.I used two variable for the prices of the types of pizzas because they are unknown.I used x for the cost of regular and y for the cost of deluxe.The equation I did are 10x+y=133 and 7x+9y=284.You need to solve one equation only.I solved the first one.

Answer:

9

Step-by-step explanation:

n=3, a=729

For any odd integer, n ; a will have only one real nth root which will be a positive integer.

Similarly, for any integer, n, that is > 1 ; related by the expression ;

p^n = a ; the nth root of a = p

Therefore,

If n = 3 ; a = 729

p^3 = 729

To obtain the value of p ; take the cube of both sides

(p^3)*1/3 = 729^1/3

p = 9

Hence, the real nth root of 729 is +9 when n = 3
