Answer:

[tex]94/99[/tex] Or [tex]0.94[/tex] as a repeating decimal

Step-by-step explanation:

Answer:

[tex] - 3(x - 1) = - 1(5 - x) \\ \\ 3 - x + 1 = - 5 + x \\ \\ - x - x = - 5 - 3 - 1 \\ \\ - 2x = - 5 - 3 - 1 \\ \\ - 2x = - 9 \\ \\ x = \frac{ - 9}{ - 2} \\ \\ x = 4.5[/tex]

[tex]3 - (x - 1) = - 1 - (5 - x)[/tex]

[tex]3 - x + 1 = - 1 - 5 + x[/tex]

[tex](3 + 1) - x = ( - 1 - 5) + x[/tex]

[tex]4 - x = - 6 + x[/tex]

[tex]4 + 6 = x + x[/tex]

[tex]10 = 2x[/tex]

[tex] \frac{10}{2} = x[/tex]

[tex]5 = x[/tex]

Answer:

9 and -3

Step-by-step explanation:

9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.

The factors of -27 that sum up to 6 are 9 and -3

From the question, we have the following parameters that can be used in our computation:

Factors = -27

Sum = 6

Let the numbers be x and y

So, we have

xy = -27

x + y = 6

Let x be 9 and y be 3

So, we have

9 * -3 = -27

9 - 3 = 6

Hence, the numbers are 9 and -3

Answer:

D. 8 1/3

Step-by-step explanation:

solve each traingle

the bottom one:

the line that cut the traingle, made each angle is 90°

10/sin90° = 5/sin?

sin? = 5sin90°/10 = 1/2

the angle is sin^-1 (1/2) = 30°   ⇒

10/sin90° = ?/sin60°

? = 10sin60°/sin90° = 5√3   ⇒

12/sin90° = 5√3/sin?

sin? = 5√3 sin90°/12 = 5√3 /12

? ≈46°

180 - (46+90) = 44°   ⇒

x/sin44° = 12/sin90°

x = 12sin44°/sin90° = 8.3

x = 8 1/3

i now the answer and the answer is o

Answer:

129

Step-by-step explanation:

Every angle would be similar to each other with having only TWO different degrees...

Each line ( <----------------------> ) equals 180 (never 360, b/c that would be a circle)

Now with you only having 51 as a degree, you need to do 180-51 which gives you 129, with that given, this tells you number 1 and 3 is both 129, and angle 2 is 51.

Answer:

  C.  (x -1)/(x +7)

Step-by-step explanation:

The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.

_____

Additional comment

Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

Answer:

7x³ + 7x² + 2x - 8

Step-by-step explanation:

Let the unknown polynomial be a

a + -3x³ + 2x - 5 = 4x³ + 7x² - 3

a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)

a = 4x³ + 7x² - 3 + 3x³ + 2x - 5

a = 7x³ + 7x² + 2x - 8

The answers to the segment addition problems are :

The required worksheet is attached below :

A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.

Given that :

LM = 22 ; MN = 15

The segment LN is defined as :

LN = LM + MN

LN = 22 + 15

LN = 37

2.)

LN = 54

LN = 54 LM = 31

The line segment, LN equals :

LN = LM + MN

54 = 31 + MN

MN = 54 - 31

MN = 23

3.)

DF = 9x - 39

DE = 47

EF = 3x + 10

The line segment, DF equals ;

DF = DE + EF

9x - 39 = 47 + (3x + 10)

9x - 39 = 47 + 3x + 10

9x - 3x = 47 + 10 + 39

6x = 96

x = 96 / 6

x = 16

Hence,

EF = 3x + 10

EF = 3(16) + 10

EF = 48 + 10

EF = 58

Answer:

20.

Step-by-step explanation:

1) according to the condition RT=ST+RS;

2) if RT=4x, ST=3x-8; RS=4x-7, then it is possible to re-write the equation as:

4x=(3x-8)+(4x-7);

3) if to solve this equation, then:

4x=7x-15; ⇔ 3x=15; ⇔ x=5.

4) if x=5, then the length of RT is:

RT=4x=20.

Answer:

y^4+10Y^3+16y^2=0

y^2(y^2+10y^1+16y^0)=0

y^2+10y+16=0

on doing. factors of 10y we get 8y+2y

y^2+8y+2y+16=0

y(y+8)+2(y+8)=0

(y+2)(y+8)=0

1.y+8=0

y=-8

2.y+2=0

y=-2

hence y =(-8,-2)

Answer:

Step-by-step explanation:

it's the relation of PV = nRT

as pressure , moles and R are held constant

V1/V2 = T1/T2

where V is volume and T is temperature in "Kelvin"

V2 = V1 * T2 / T1

V2 = 90 * 315 / 300

Point (9, 6) would be on the inverse of this function so option (D) will be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the sets of coordinates of a function.

An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.

For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.

Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.

Hence "Point (9, 6) would be on the inverse of this function".
