Answer:

  T = (-12, 19)

Step-by-step explanation:

We know that the definition of the midpoint is ...

  M = (S + T)/2

Solving for T gives ...

  T = 2M -S

  T = 2(-10, 14) -(-8, 9) = (-20+8, 28-9)

  T = (-12, 19)

Answer:

y = 1/5x + 3

Step-by-step explanation:

parallel lines have the same slope

y = 1/5x + b

4 = 1/5(5) + b

4 = 1 + b

b = 3

y = 1/5x + 3

[tex]7.25 \leqslant x[/tex]

Step-by-step explanation:

you do 1.5×8 to see how much shipping cost

you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25

so he needs to spend $7.25 or more on each friend. (im pretty sure)

The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.

Let the cost of each gift = c

urgio is buying gifts for 8 friends = 8 gifts

Hence, the Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

Answer:

[tex] x = \frac{300}{b} [/tex]

Step-by-step explanation:

We are given that, "b" number of buildings has 300 windows.

Let b represent the number of buildings.

Let x represent the number of windows per building.

Thus, the following equation can be used to expressed the number of windows for b buildings:

Number of buildings*number of windows per building = 300 windows

[tex] x*b = 300 [/tex]

The number of windows each building has would be:

[tex] \frac{x*b}{b} = \frac{300}{b} [/tex]

[tex] x = \frac{300}{b} [/tex] windows per building

Answer:

4th=8 dots

5th=10 dots

100th=200 dots

Step-by-step explanation:

Since you’re adding two dots each time, it will always bed double the figure number.

4th=8 dots

5th=10 dots

100th=200 dots

Answer:

The fourth figure is 8 Dots

The fifth figure is 10 Dots

The hundredth figure will be 200 Dots

Step-by-step explanation:

The figure dots increase by two so we multiply the dot number by the amount of increase

which means

The Fourth figure have 4 dots so 4 × 2=8

The Fifth figure have 5 dots so 5 × 2 =10

The hundredth figure have 100 dots so 100 × 2 =200

Answer:

Step-by-step explanation:

w  = -3 and 21/25

The value of w in 7/60=5/24w+11/12 is 6/5.

Given,

7/60 = 5/24 w + 11/12

We need to solve for w.

It depends on the type of equation given.

We need to keep the variable that we are solving for in one side and simplify the other terms.

Find the value of w.

We have,

7/60 = 5/24 w + 11/12

Subtract 11/12 on both sides.

7/60 - 11/12 = 5/24 w + 11/12 - 11/12

7/6 - 11/12 = 5/24 w

Simplify the left-hand side into a fraction.

(14 - 11 ) / 12 = 5 / 24 w

3 / 12 = 5 / 24 w

Multiply 24 / 5 on both sides.

24/5 x 3/12 = 24/5 x 5/24 w

6 / 5 = w

w = 6 / 5

Thus the value of w in 7/60=5/24w+11/12  is 6/5.

Answer:

El contador que señala 840 registra de 3 en 3.

Step-by-step explanation:

Existe un truco para determinar si un número es múltiplo de 3, si la suma de sus dígitos es 3 o uno de sus múltiplos, entonces el número es un múltiplo de 3. En consecuencia, corresponde al contador eléctrico que registra de 3 en 3 y el otro contador eléctrico sería el que registra de 5 en 5.

Primer contador: 840

[tex]x = 8+4+0[/tex]

[tex]x = 12[/tex]

12 es un múltiplo de 3, por tanto, este contador es el que registra de 3 en 3.

Segundo contador: 560

[tex]x = 5+6+0[/tex]

[tex]x = 11[/tex]

11 no es un múltiplo de 3. Asimismo, todo número que sea múltiplo de 5 termina en 5 o 0, entonces este contador es el que registra de 5 en 5.

So we have the function:

And we want to find:

[tex]g(s+1)[/tex]

So, substitute y for (s+1):

[tex]g(y)=7-6y\\g(s+1)=7-6(s+1)\\[/tex]

Distribute:

[tex]g(s+1)=7-6s-6[/tex]

Subtract:

So we have the function:

And we want to find:

[tex]h(x-3)[/tex]

So, substitute t for (x-3):

[tex]h(t)=t^2-2t\\h(x-3)=(x-3)^2-2(x-3)[/tex]

Answer:

13½ kilometers

Step-by-step explanation:

If Nina runs 4½ km in ⅓ of an hour, at this pace, the number of km she'd run in an hour can be calculated as follows.

Let x be the number of km to run in an hour.

4½km => ⅓ hr

x km => 1 hr

Cross multiply

[tex] 1*4\frac{1}{2} = \frac{1}{3}*x [/tex]

[tex] 4\frac{1}{2} = \frac{x}{3} [/tex]

Multiply both sides by 3

[tex] 4\frac{1}{2}*3 = \frac{x}{3}*3  [/tex]

[tex] \frac{9}{2}*3 = x  [/tex]

[tex] \frac{27}{2} = x [/tex]

[tex] 13\frac{1}{2} = x [/tex]

x = number of km Nina runs in 1 hour = 13½ kilometers

Answer:

22

Step-by-step explanation:

Given that T is the midpoint of line PQ, segments PT = 5x + 2, and TQ = 7x - 6 that are formed would be equidistant or congruent. PT = TQ.

Therefore:

[tex] 5x + 2 = 7x - 6 [/tex]

Let's find the value of x

Rearrange the equation, so that the terms having x would be on your left, while those without x would be on your right.

[tex] 5x - 7x = - 2 - 6 [/tex]

[tex] -2x = -8 [/tex]

Divide both sides by -2

[tex] x = 4 [/tex]

Plug in the value of x into the expression, 5x + 2, to find PT.

PT = 5(4) + 2 = 22.

Answer: 8

Step-by-step explanation:

Let mammals be represented by y

There are three more reptiles than mammals in the habitat. Therefore, Reptiles = y + 3

There are seven fewer amphibians than mammals in the habitat. Therefore, amphibian = y - 7

y + y + 3 + y - 7 = 41

3y - 4 = 41

3y = 41 + 4

3y = 45

y = 45/3

y = 15

Since amphibian = y - 7

= 15 - 7

= 8

There are 8 amphibians
