Answer:

[tex]\boxed{\boxed{\sf 6x^3+9x^2+6x-9}}[/tex]

Step-by-step explanation:

[tex]\sf \left(8x^3+3x-2\right)+\left(9x^2-7+3x-2x^3\right)[/tex]

[tex]\sf 8x^3+3x-2+9x^2-7+3x-2x^3[/tex]

Note: If there is a negative sign in front of  parentheses, each term within the expression changes sign.

[tex]\Longrightarrow \sf 8x^3+3x-2+9x^2-7+3x-2x^3[/tex]

Now, we need to organize expression into groups like terms:

[tex]\Longrightarrow \sf (8x^3, -2x^3)\: (3x, 3x)\:(-2,-7)[/tex]

[tex]\longmapsto\sf 8x^3-2x^3=6x^3[/tex]

[tex]\longmapsto\sf 3x+3x=6x[/tex]

[tex]\longmapsto\sf -2-7=-9[/tex]

[tex]\boxed{\sf 6x^3+9x^2+6x-9}[/tex]

Answer:

C

Step-by-step explanation:

Equations of lines that are perpendicular have gradients that are negative reciprocals of each other. This means that the gradient of one of the lines is negative 1 times the fraction flipped.

With the equations presented in the form y = mx + c, the gradient is m. This means you need to look for the values of m where one is the negative reciprocal of the other.

In C, the first gradient is 6/11. The reciprocal (flipped) is 11/6. Make this negative and you get -11/6, which is the gradient of the second equation, so these lines are perpendicular.

19th. = 120 yds

plzz plzzz plzz mark as brainliest.

Answer:

72m

Step-by-step explanation:

since 5cm is 6m, just take 5 and make it 6, so 10cm is 12m and 5cm is 6m

multiply, and you get the answer

Answer:

I think the answer is 4.5,2

I think that is the answer.

Answer:

[tex]x<-6; x\ge2[/tex]

Step-by-step explanation:

We're taking values from -6 and behind, and the dot over -6 is empty, so it's not included. That means [tex]x<-6[/tex]. Moreover, the rest of the line goes from 2, with a solid dot, and ahead. That translates in [tex]x\ge 2[/tex]

Step-by-step explanation:

2b - 3/3 - 5 = 10

2b - 1 - 5 = 10

2b - 6 =10

2b -6 +6 = 10 +6

2b = 16

b = 8

Answer:total is 180. Subtract 100. Then it’s 80

Step-by-step explanation:

180-100=80 degrees. It applies for the ones across.

In basic the answer is x=80

Let x = 0.757575... . Then

100x = 75.757575...

and so

100x - x = 75.757575... - 0.757575...

99x = 75

x = 75/99 = 25/33

Answer:

Sara's mother age : 40 years

Sara's age : 10 years

Step-by-step explanation:

Let Sara's mother age be x

and Sara age be y

Given , Sara's mother is now four time as old as Sara

• x = 4y ...1

also, in five years , she will be three times as old as Sara

In five years , Sara's mother age :- ( x + 5 )

Sara age :- ( y + 5 )

according to the question,

x + 5 = 3 ( y + 5 )

x + 5 = 3y + 15

x - 3y = 10 ... 2

putting value of x from 1 into 2

4y - 3y = 10

y = 10

putting y value in 1

x = 4y = 4 ( 10 ) = 40

So, Sara's mother age is 40years

and Sara's age is 10years .

Answer:

(x+8, y+4).

Step-by-step explanation:

8 units to the right followed by 4 units up.

Step-by-step explanation:

I understand from the corrupted typing of the problem text that we have 2 functions :

h(x) = x² + 11

g(x) = sqrt(x - 2)

we are looking for (g○h)(0).

first of all, (g○h)(0) is the same as g(h(0)).

don't get in panic because of this one iteration sign.

it just means we are running the second function first, and use that result as argument for the first function. that's all.

so,

h(0) = 0² + 11 = 11

11 is now the argument for g(x).

g(11) = sqrt(11 - 2) = sqrt(9) = 3

(g○h)(0) = 3

Step-by-step explanation:

Answer:

m ∠ A = 139° ; m ∠ B = 41°

Step-by-step explanation:

Supplementary angles sum = 180°

m ∠A + m ∠ B = 180°

 (7x - 15) + (2x - 3) = 180°

9x - 18 = 180°

9x = 180 + 18

9x = 198°

x = 22

m ∠A  = 7x - 15 = (7·22) - 15 = 154 - 15 = 139°

m ∠ B = 2x - 3 = (2·22) - 3 = 44 - 3 = 41°

Check:  m ∠ A + m ∠ B = 180°

                 139° + 41° = 180

Rearrange terms

2(4+9m)

2(9m+4)

Distribute

2(9m+4)

18m+8

Solution

Solution18m+8

[tex]2(4+9m)[/tex]

[tex]2(9m+4)[/tex]

[tex]18m+8[/tex]

(Therefore, 18m+8 is the final answer)

Answer:  

y = -3 * x + 5

Step-by-step explanation:  

We start with the equation for slope-intercept y = mx + b -  

Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.  

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -  

(8 - (-1)) / ((-1) - 2)  

9 / (-3)  

Slope = -3  

Now we insert the slope into the equation -  

y = -3 * x + b  

As said before, Y is any y point on the line and X is any x point on the line, so we can choose a random point and insert it in to find the y-intercept -    

-1 = -3 * 2 + b  

-1 = -6 + b  

b = 5

The y-intercept of the line is (0, 5)  

We insert the y-intercept in the equation -  

y = -3 * x + 5  

y = -3 * x + 5 is our answer to the problem.

Answer:

Quadrants I and II

Step-by-step explanation:

y = x²

y = 3x + 10

x² = 3x + 10                     Substitute x² for y

x² - 3x - 10 = 0                 set the equation = 0

(x - 5) (x + 2)                     Factoring

x - 5 = 0 ; x + 2 = 0

x = 5 or x = -2

Now solving the y

y = x²     or     y = x²

y = (5)²   or y = (-2)²  

y = 25   or  y = 4

The points of interception is points (5, 25) or (-2, 4)  

(5, 25)  in Quadrant I ; (-2, 4) in Quadrant II
