What is the value of T(−4) when T(x)=−x−2?

Answer:

Step-by-step explanation:

All the angles within a triangle equals to 180, and that square thing at a corner of the triangle means that the angle is 90 degrees, so:

20+6x+16+90=180

add stuff

6x+126=180

subtract 126 from both sides

6x=54

divide 6 from both sides

x=9

Answer:

9y + 4z + 9x

Step-by-step explanation:

Answer:

6x * 1/2 - 3 (* means multiplying)

Step-by-step explanation:

In this problem, you are using communitive property and so you are just changing the problem to an equal situation.

The equivalent expression of 4x + 1/2 + 2x - 3 is 6x - 8/3.

Given is the expression -

4x + 1/2 + 2x - 3

We have the following expression -

4x + 1/2 + 2x - 3

Solving further -

4x + 2x - 3 + 1/3

6x + 1/3 - 3

6x + (1 - 9)/3

6x - 8/3

Therefore, the equivalent expression of 4x + 1/2 + 2x - 3 is 6x - 8/3.

Answer:

Shopper spend $3 on Apples, $4 on Grapes and $3.5 on Oranges

Step-by-step explanation:

Cost of one pound of Apple = $2x

Cost of one pound of Grapes = $(6x-5)

Cost of one pound of Oranges = $(x+2)

A shopper purchases one pound each of  apples, grapes, and oranges and spends  $10.50.

It can be written as: [tex]2x+6x-5+x+2=10.50[/tex]

We need to find how much the shopper spend on each fruit.

First we need to find value of x by solving equation

[tex]2x+6x-5+x+2=10.50[/tex]

Solving:

[tex]2x+6x+x+2-5=10.50\\9x-3=10.50\\9x=10.50+3\\9x=13.5\\x=\frac{13.5}{9}\\x=1.5[/tex]

The value of x is: x=1.5

Now finding cost of one pound each fruit by putting x=1.5

Cost of one pound of Apple = $2x = 2(1.5) = $3

Cost of one pound of Grapes = $(6x-5) = (6(1.5)-5)= $4

Cost of one pound of Oranges = $(x+2)=(1.5+2)=$3.5

So,

Cost of one pound of Apple  = $3

Cost of one pound of Grapes = $4

Cost of one pound of Oranges = $3.5

So, shopper spend $3 on apples, $4 on Grapes and $3.5 on Oranges

Answer:

The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American Revolution.

Step-by-step explanation:

Answer:

The ship S is at 10.05 km to coastguard P, and 12.70 km to coastguard Q.

Step-by-step explanation:

Let the distance of the ship to coastguard P be represented by x, and its distance to coastguard Q be represented by y.

But,

<P = 048°

<Q = [tex]360^{o}[/tex] - [tex]324^{o}[/tex]

     = 0[tex]36^{o}[/tex]

Sum of angles in a triangle = [tex]180^{o}[/tex]

<P + <Q + <S = [tex]180^{o}[/tex]

048° + 0[tex]36^{o}[/tex] + <S = [tex]180^{o}[/tex]

[tex]84^{o}[/tex] + <S = [tex]180^{o}[/tex]

<S  = [tex]180^{o}[/tex] -  [tex]84^{o}[/tex]

    = [tex]96^{o}[/tex]

<S = [tex]96^{o}[/tex]

Applying the Sine rule,

[tex]\frac{y}{Sin P}[/tex] = [tex]\frac{x}{Sin Q}[/tex] = [tex]\frac{z}{Sin S}[/tex]

[tex]\frac{y}{Sin P}[/tex] = [tex]\frac{z}{Sin S}[/tex]

[tex]\frac{y}{Sin 48^{o} }[/tex] = [tex]\frac{17}{Sin 96^{o} }[/tex]

[tex]\frac{y}{0.74314}[/tex] = [tex]\frac{17}{0.99452}[/tex]

⇒ y = [tex]\frac{12.63338}{0.99452}[/tex]

       = 12.703

y = 12.70 km

[tex]\frac{x}{Sin Q}[/tex] = [tex]\frac{z}{Sin S}[/tex]

[tex]\frac{x}{Sin 36^{o} }[/tex] = [tex]\frac{17}{Sin 96^{o} }[/tex]

[tex]\frac{x}{0.58779}[/tex] = [tex]\frac{17}{0.99452}[/tex]

⇒ x = [tex]\frac{9.992430}{0.99452}[/tex]

      = 10.0475

x = 10.05 km

Thus,

the ship S is at a distance of 10.05 km to coastguard P, and 12.70 km to coastguard Q.

René Descartes

Step-by-step explanation:

René Descartes ( March 31, 1596 – February 11, 1650), also known as Cartesius, was a noted French philosopher, mathematician, and scientist. Dubbed the "Founder of Modern Philosophy" and the " Father of Modern Mathematics," he ranks as one of the most important and influential thinkers of modern times.

Answer:

the one clue you have is "30,12" on the left. try to understand how they relate to each other. maybe how many times 12 goes into 30. or maybe how many times it goes into 32 with no decimal so what number do you have to add (sometimes work doesnt mean it like that so that might be wrong). but if you want the answers, they are:

35/5/15/30

14/2/6/12

the way i did it was if it was on the bottom (y) i did 2.5 times the number. if on the top (x) i did the number divided by 2.5. 2.5 was the rate of change (is that the word i think it is but if it isnt just blame me im sorry).

Answer:

-4.3, -3.4, -0.43, -0.34, -0.043

Answer:

X>0, so the second one

Step-by-step explanation:

Since the point on 0 is OPEN that means the number (0) is NOT part of the solution. Therefore, X is greater than 0.

Answer:

11025

Step-by-step explanation:

100+5÷100=1.05 squared

10000x1.05squared=11025

Answer:

Amount = 11205

CI = 1205

Step-by-step explanation:

[tex]a = p(1 + \frac{r}{n} ) {}^{nt} [/tex]

Here,

p = 10000

r = 5% = 5/100 = 0.05

n = 1

t = 2

[tex]a = 10000(1 + \frac{0.05}{1} ) {}^{1 \times 2} [/tex]

[tex]a = 10000(1.05) {}^{2} [/tex]

[tex]a = 10000(1.1025)[/tex]

[tex]a = 11205[/tex]

C.I = a - p

C.I = 11205 - 10000

C.I = 1205

Answer:

x = 1

Step-by-step explanation:

Δ ABC and Δ DEF are congruent ( SAS postulate )

Thus corresponding sides are congruent that is

BC = EF , substitute values

13x - 12 = 7x - 6 ( subtract 7x from both sides )

6x - 12 = - 6 ( add 12 to both sides )

6x = 6 ( divide both sides by 6 )

x = 1
