Answer:

associative property of addition !!

Step-by-step explanation:

this is because you are ASSOCIATING the two numbers together

think of it like this

in a trio friendship there could be two friends that are closer

the 8 and the 10 in the second half of the equation are closer

BUT in the first half the 3 and the 8 are closer too

hope that made sense lol

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

Answer:

4

Step-by-step explanation:

you can start with the division -24 ÷ -8 = 3

(-) ÷ (-) = (+)

then multiply 3 × 4 = 12

then divide it by 3

12÷ 3 which equals 12 × (1/3) = 4

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:

A.

Step-by-step explanation:

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".

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)

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:

477.09 mi/da

Step-by-step explanation:

If student must use conversion given, 3.28ft = 1m, then the following works:

32km/hr = ______mi/da       1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft

32km/hr  x  24hr/day  x  1000m/1km  x  3.28ft/1m  x  1mi/5280ft  = 477.09mi/da

If student can use 1km = 0.62mi, some steps can be skipped.

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

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.

Option A. 3.2 x 10²

Step-by-step explanation:

320 written in scientific notation is 3.2 × 102.

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
