What is the vertex form of the function: f(x) = -12x - 6x^2- 13?

Answer:

Answer:

y=4 because 8x4=32

32-2 =30

30+60=90

Answer:

the value of y is 4, so 8(4)-2 are 30 , then 30 degrees are the angle

Step-by-step explanation:

The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).

The expressions that represent the perimeter of the square are  p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given:

The side of the square is 6m-3 unit.

And all the sides of the squares are equal.

And the perimeter p of the square is,

= the sum of all the sides.

p = 4 x one side.

p = 4(6m-3)

The above expression represents the perimeter of the given square.

Simplifying,

p = 24m - 12

This is the simplest form of the expression.

Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.

Answer:

16%

Step-by-step explanation:

406 / 350 = 1.16

406 is 116% of 350

so 350 + 16% is 406

because 350 * 0.16 = 56

56 is 16%

350 + 56 = 406

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

Step-by-step explanation:

since it's square units and this is a right triangle

area = (width * height) / 2

area = 6 * 3 / 2

area = 18 / 2

area = 9 square units²

Answer:

9 [tex]units^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a triangle is [tex]A=\frac{1}{2}b*h[/tex] where b is the base or bottom of the triangle and h is the height of the triangle.

The base of the triangle in the picture is 6 units.

The height of the triangle in the picture is 3 units.

Substituting these values into the area formula:

[tex]A=\frac{1}{2}(6*3)=\frac{1}{2}(18)=9[/tex]

So the area of the triangle is 9 [tex]units^{2}[/tex]

hope you like my answer its 2/7

Answer:

7) No

8) Yes

Step-by-step explanation:

7) 15 + 2y = -12 - 4y when y = -0.5

15 + (2*-0.5) = -12 - (4*-0.5)

15 + -1 = -12 - (-2)

15 - 1 = -12 + 2

14 = -10

The numbers are different on both sides so -0.5 is not a solution

8) 5 - 2( 3x + 5 ) = 3 - 10x when x = 2

5 - 2( (3*2) + 5 ) = 3 - (10*2)

5 - 2( 6 + 5 ) = 3 - 20

5 - 2*11 = 3 - 20

5 - 22 = 3 - 20

-17 = -17

The numbers are similar on both sides so 2 is a solution

Answer:

E    see below

Step-by-step explanation:

When dividing two fractions, you flip the second fraction over then multiply.

So the equation would then be:

3xy (2 + y)           ab

---------------  X   --------------

     2ab                3xy

The 3xy on top and bottom cancel each other out.  The ab on top and bottom cancel each other out.

So you are left with:

2 + y

-------

   2

Answer: Number E is correct.

Step-by-step explanation:

division becomes multiplication and turns upside down. ab cuts ab and 2 remains as denominator. 3xy cuts 3xy and 2+y remains as numerator. Therefore the answer obtained is 2+y/2.

Answer:

18 crayon in both boxes.

Step-by-step explanation:

Asked:  Greatest number of equal crayons in both boxes.

Facts:

Number of crayons in pack 1 = 24

Number of crayons in pack 2 = 12

Total crayons in both packs  = 24 + 12 = 36

Plan:

If both packs need to have equal crayons, then it should be dived by 2.

Solution:

36 ÷ 2 = 18

Answer:

10

Step-by-step explanation:

Use Pythagorean theorem,

8² + altitude² = (2√41)²

64 + altitude² = 2²*(√41)²              {(√41)² = √41*√41 = 41}

64 +altitude² = 4 * 41

64 +altitude² = 164

      altitude² = 164 - 64

      altitude² = 100

      altitude = √100 = 10

I Had A Problem In This Too Lol Here Was Correct For Me

Step-by-step explanation:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Answer:

slope = 1

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}x_{1} }[/tex]

with (x₁, y₁ ) = (- 10, 9 ) and (x₂, y₂ ) = (-12, 7 )

Option B is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.
